How an Alabama Town Is Fighting Against Cancerous & Toxic Coal Ash Dumping—No Thanks to Trump’s EPA
https://democracynow.org - Residents of Uniontown, Alabama, have lived with the Arrowhead landfill, which is twice the size of New York’s Central Park, have protested shipments of toxic coal ash—the residual byproduct of burning coal—from a massive spill in Kingston, Tennessee, believed to be the largest coal ash disaster in U.S. history. For two years, nearly 4 million tons of coal ash was also shipped by rail from a mostly white Tennessee county to Uniontown. Coal ash contains toxins, including arsenic, mercury and boron, that can affect the nervous and reproductive systems and cause other health problems. According to the EPA, people living within a mile of unlined coal ash storage ponds have a one-in-50 risk of developing cancer. In 2013, some Uniontown residents filed a complaint under Title VI of the Civil Rights Act. This week, the EPA dismissed the claim, saying there was “insufficient evidence.” We speak with Ben Eaton, vice president of Black Belt Citizens Fighting for Health and Justice and a resident of Uniontown, Alabama; and with Mustafa Santiago Ali, former head of the EPA’s environmental justice program.

Beryllium Health Effects on Workers
Dr. John Balmes, Director of the Center for Occupational and Environmental Health, will review recommendations for practitioners regarding the diagnosis and management of beryllium sensitivity and chronic beryllium disease published in an official American Thoracic Society (ATS) statement in 2014. The ATS statement was prepared with the support and input of both NIOSH and the U.S. Department of Labor (DOL). The DOL runs the Energy Employees Occupational Illness Compensation Act that provides medical monitoring and compensation for eligible employees of U.S. Department of Energy (DOE) facilities who develop beryllium sensitization and chronic beryllium disease as a consequence of their employment at a DOE facility. Dr. Balmes will also discuss federal OSHA’s new Final Rule to Protect Workers from Beryllium Exposure.

14| Use of Lake Sediments to Establish Baseline and Evaluate for Pollution (Peace-Athabasca Delta)
Roland Hall Use of Lake Sediments to Establish Baseline and Evaluate for Pollution at the Peace-Athabasca Delta The extent to which Alberta oil sands development enhances delivery of contaminants via the Athabasca River and atmosphere to the Peace-Athabasca Delta is a pivotal question that generates national and international concern. Deciphering relative contributions of natural versus industrial processes on supply of polycyclic aromatic compounds (PACs) and metals has been identified as a critical knowledge gap, but remains a formidable scientific challenge because loading from natural processes remains unknown and industrial activity occurs in the same locations as the natural bitumen deposits. Here, we present results from analyses of sediment cores from strategically-selected lakes within the Peace-Athabasca Delta, 200 km north of Fort McMurray, to determine pre-industrial baseline contaminant levels and evaluate for evidence of pollution. The results demonstrate that air pollution of heavy metals has declined in the Delta despite oilsands development, organic contaminants carried by the Athabasca River to the Athabasca Delta have not increased above pre-development levels in sediments of a flood-prone lake, and heavy metal concentrations in downstream Athabasca River surface sediment have not increased above levels that existed 14 Program • DAY 1 before oilsands development. Our findings suggest natural erosion of exposed bitumen in banks of the Athabasca River and its tributaries is a major process delivering contaminants to the Delta, and the spring freshet is a key period for contaminant mobilization and transport. This baseline environmental information is essential for informed management of natural resources by provincial and federal regulatory agencies and industry, and for designing effective long-term monitoring programs for the lower Athabasca River watershed.
Aldridge Minerals: five mineral plays in one
Aldridge Minerals Inc’s (CVE:AGM) chief executive officer Han Ilhan outlines the benefits of having a polymetallic deposit, which lessens the impact of price fluctuations in any particular commodity. The company’s deposits are split roughly equally between precious metals and base metals. “We have a significant precious metals content but on the base side, the zinc is about 900mln pounds, so that gets a lot attention in the marketplace," he said. The company has done an impressive 70,000 metres of drilling over the last ten years at its flagship project, Yenipazar, in central Turkey. Ilhan said the company has received good support from the Turkish authorities, with the Environmental Impact Assessment completed in just seven months, while an important permitting application was whizzed through by the region’s governor in two months. The local inhabitants, many of whom are subsistence farmers, have also been supportive of the project and see the mine, when it has been built, as an alternative source of income for the region. The company expects to complete all the land acquisition for the project in the first half of next year. “In parallel, we’re going through a project financing. We expect the project financing to be complete by the end of next year,” Ilhan revealed. Once the financing is in place, construction will start, and that, on a conservative estimate, should take 33 months, though Ilhan personally thinks it will take as long as that. “Target production is somewhere between end of 2019 and the early part of 2020,” the Alridge CEO told Proactive Investors. Ilhan places great store in the company’s executives being close to the asset. “To manage and monitor the activities remotely is dangerous,” he believes. The Aldridge boss uprooted himself from the US to live in Turkey, and said it was not a a particularly difficult decision to make. “What’s important for me is to use this project to build a company, and that’s what I am excited about.”

Malakoff Diggins State Historic Park - Movie (HD)
California's history is defined by the era known as "The Gold Rush", a peiod that began in 1849 when gold was discovered near Sacramento. From that moment on, California was known as "The Golden State". But most people aren't aware that the gold rush ended when some of America's first environmental protection laws went into effect to stop hydraulic strip mining - the process of washing away hillsides to extract gold - and put the state on it's path to recovery.

The Office of Environment, Health and Safety, UC Berkeley, rates silver iodide as a Class C, non soluble, inorganic, hazardous chemical that pollutes water and soil. It has been found to be highly toxic to fish, livestock and humans. Numerous medical articles demonstrate that humans absorb silver iodide through the lungs, nose, skin, and GI tract. Mild toxicity can cause GI irritation, renal and pulmonary lesions, and mild argyria (blue or black discoloration of the skin). Severe toxicity can result in hemorrhagic gastroenteritis, shock, enlarged heart, severe argyria, and death by respiratory depression. Moreover, a key manufacturer of silver iodide for weather modification, Deepwater Chemicals, warns of potential health effects of silver iodide in their Material Safety Data Sheet as follows: Chronic Exposure/Target Organs: Chronic ingestion of iodides may produce "iodism", which may be manifested by skin rash, running nose, headache and irritation of the mucous membranes. Weakness, anemia, loss of weight and general depression may also occur. Chronic inhalation or ingestion may cause a rgyria characterized by blue-gray discoloration of the eyes, skin and mucous membranes. Chronic skin contact may cause permanent discoloration of the skin. Under the guidelines of the Clean Water Act by the EPA, silver iodide is considered a hazardous substance, a priority pollutant, and as a toxic pollutant. Some industries have learned this all too well....According to the PGCD, "Every year, two viable samples of rainwater must be sent to a laboratory for analysis and in return forwarded to TNRCC to ensure that the water is not contaminating the area." This is faulty sampling and testing over a seven county area. If PGCD can not control where the seeded clouds dumps water, how can they take only two rain samples per year to test for silver concentrates of the clouds they seeded? At least it is an admission that silver toxicity is an issue. Such misleading statements based on faulty data are not uncommon to the PGCD. In 2001, rainfall amounts were grossly over inflated in multiple rain gauges. Such overstatements are to prop up the benefits of their program while denying the adverse effects. To effectively monitor the levels of silver toxicity, at the very minimum, water samples should be taken on a monthly basis from every dam, creek, stock tank, and other water capture places in the respective district while cloud seeding is being conducted. Also, soil samples should taken. According to the Colorado National Park Service and the Federal Remediation Technologies Roundtable, the result of cloud seeding with silver iodide and run off have adverse effects on the water, soil, and flora and fauna. "Elevated silver concentrations in biota occur in the vicinities of sewage outfalls, electroplating plants, mine waste sites, and silver iodide-seeded areas." In fact, in the 1980s the CDC had hoped that silver toxicity would be reduced nationally based on a reduction of cloud seeding activity. "Fallout from cloud seeding with silver iodide is not always confined to local precipitation; silver residuals have been detected several hundred kilometers down wind of seeding events." "Anthropogenic sources associated with the elevated concentrations of silver in nonliving materials include smelting, hazardous waste sites, cloud seeding with silver iodide, metals mining, sewage outfalls, and especially the photo processing industry." Silver leaches into groundwater, streams, soil, and the root systems of plants. "Silver was measured in particular samples from rural and urban area both adjacent to and removed from activities such as metal smelting, refining, and silver iodide cloud seeding" and found "concentrations in precipitation resulting from seeding clouds with silver iodide were 10-450 ng/L compared with concentrations of 0-20ng/L without cloud seeding (Cooper and Jolly 1970)." That translates in 10 to 225 times greater silver concentration in those areas.

Beryllium - New Rule to Protect Workers from Occupational Exposures
The Occupational Safety and Health Administration (OSHA) has issued a final rule to prevent chronic beryllium disease (CBD) and lung cancer in American workers by limiting their exposure to beryllium and beryllium compounds. The new standards contained in the final rule took effect in March of 2017. Beryllium is a lightweight and strong metal used in the aerospace, electronics, energy, telecommunications, medical and defense industries. Beryllium and beryllium compounds are important materials, but beryllium is also a highly toxic metal and workers who inhale it are at an increased risk of developing chronic beryllium disease or lung cancer. OSHA reports that chronic beryllium disease is a serious pulmonary disease that can cause debilitation or death. Signs and symptoms of CBD can include shortness of breath, an unexplained cough, fatigue, weight loss, fever and night sweats. Lung cancer is associated with occupational exposure to beryllium by inhaling beryllium containing dust, fumes or mist. The International Agency for Research on Cancer (IARC) lists beryllium as a Group 1 carcinogen (causes cancer in humans), and the National Toxicology Program (NTP) lists beryllium as a known human carcinogen. Key provisions of the new rule: • Reduce the permissible exposure limit (PEL) for beryllium to 0.2 micrograms per cubic meter of air, averaged over 8-hours. • Establishes a new short term exposure limit for beryllium of 2.0 micrograms per cubic meter of air, over a 15-minute sampling period. • Requires employers to: use engineering and work practice controls (such as ventilation or enclosure) to limit worker exposure to beryllium; provide respirators when controls cannot adequately limit exposure; limit worker access to high-exposure areas; develop a written exposure control plan; and train workers on beryllium hazards. • Requires employers to make available medical exams to monitor exposed workers and provides medical removal protection benefits to workers identified with a beryllium-related disease. These are just a few things to know about potential occupational exposures to beryllium and OSHA’s new final rule.

What is BERYLLIOSIS? What does BERYLLIOSIS mean? BERYLLIOSIS meaning, definition & explanation
What is BERYLLIOSIS? What does BERYLLIOSIS mean? BERYLLIOSIS meaning - BERYLLIOSIS pronunciation - BERYLLIOSIS definition - BERYLLIOSIS explanation - How to pronounce BERYLLIOSIS? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Berylliosis, or chronic beryllium disease (CBD), is a chronic allergic-type lung response and chronic lung disease caused by exposure to beryllium and its compounds, a form of beryllium poisoning. It is distinct from acute beryllium poisoning, which became rare following occupational exposure limits established around 1950. Berylliosis is an occupational lung disease. The condition is incurable, but symptoms can be treated. Berylliosis is an occupational disease. Relevant occupations are those where beryllium is mined, processed or converted into metal alloys, or where machining of metals containing beryllium and recycling of scrap alloys occurs. It is associated with aerospace manufacturing, microwave semiconductor electronics, beryllium mining or manufacturing of fluorescent light bulbs (which once contained beryllium compounds in their internal phosphor coating). Beryllia was used in lamp manufacture because of ceramic's obvious virtues for insulation and heat resistance, and also because beryllia could be made transparent. Certain welding anodes along with other electrical contacts and even non-sparking tools are made of beryllium copper alloy and the subsequent machining of such materials would cause the disease as well. With single or prolonged exposure by inhalation the lungs may become sensitized to beryllium. Berylliosis has an insidious onset and runs an indolent course. Some people who are sensitized to beryllium may not have symptoms. Continued exposure causes the development of small inflammatory nodules, called granulomas. Of note, the authors of a 2006 study suggested that beryllium inhalation was not the only form of exposure and perhaps skin exposure was also a cause, as they found that a reduction in beryllium inhalation did not result in a reduction in CBD or beryllium sensitization. Granulomas are seen in other chronic diseases, such as tuberculosis and sarcoidosis, and it can occasionally be hard to distinguish berylliosis from these disorders. Note, however, that the granulomas of CBD will typically be non-caseating, i.e. not characterized by necrosis and therefore not exhibiting a cheese-like appearance grossly. Ultimately, this process leads to restrictive lung disease (a decrease in diffusion capacity). The earliest symptoms are typically cough and shortness of breath. Other symptoms include chest pain, joint aches, weight loss, and fever. Rarely, one can get granulomas in other organs including the liver. The onset of symptoms can range from weeks up to tens of years from the initial exposure. In some individuals a single exposure can cause berylliosis. In susceptible persons, beryllium exposure can lead to a cell-mediated immune response. The T-cells become sensitized to beryllium. Each subsequent exposure leads to an immune response involving CD4+ helper T-lymphocytes and macrophages accumulating in the lungs. As this response continues macrophages, CD+4 T-lymphocytes and plasma cells aggregate together to form the noncaseating granulomas. Eventually, the final outcome is fibrosis of the lung. Several studies have shown that there is a genetic component to beryllium sensitivity. Specifically, those beryllium exposed workers with a mutation at the HLA-DPB1 Glu69 position have increased prevalence of beryllium sensitization and CBD. The HLA-DPB1 gene is important for MHC class II molecule function on antigen presenting cells. According to the International Agency for Research on Cancer (IARC), beryllium and beryllium compounds are Category 1 carcinogens; they are carcinogenic to both animals and humans. There is no cure for berylliosis; the goals of treatment are to reduce symptoms and slow the progression of disease. Although the evidence that stopping exposure to beryllium decreases progression of the disease, it is still considered to be an accepted approach to treatment in any stage of disease. People with early stages of disease, without lung function abnormalities or clinical symptoms, are periodically monitoring with physical exams, pulmonary function testing and radiography. Once clinical symptoms or significant abnormalities in pulmonary function testing appear, treatments include oxygen and oral corticosteriods and whatever supportive therapy is required.

Examples of Heavy Metals
http://balancedhealthtoday.com/buy/medicardium-edta-heavy-metal-cleanse/ Call Now 1(888)277-4980 Email [email protected] Examples of heavy metals include lead, mercury and cadmium. Less commonly, any metal with a potential negative health effect or environmental impact may be termed a heavy metal, such as cobalt, chromium, lithium and even iron. Dispute over "Heavy Metal" Term According to the International Union of Pure and Applied Chemistry or IUPAC, the term "heavy metal" may be a "meaningless term" because there is no standardized definition for a heavy metal. Some light metals or metalloids are toxic, while some high-density metals are not. For example, cadmium generally is considered a heavy metal, with an atomic number of 48 and specific gravity of 8.65, while gold typically is not toxic, even though it has an atomic number of 79 and specific gravity of 18.88. For a given metal, the toxicity varies widely depending on the allotrope or oxidation state of the metal. Hexavalent chromium is deadly; trivalent chromium is nutritionally significant in many organisms, including humans. Certain metals, such as copper, cobalt, chromium, iron, zinc, manganese, magnesium, selenium, and molybenum, may be dense and/or toxic, yet are required micronutrients for humans or other organisms. The essential heavy metals may be needed to support key enzymes, act as cofactors, or act in oxidation-reduction reactions. While necessary for health and nutrition, excess exposure to the elements can cause cellular damage and disease. Specifically, excess metal ions can interact with DNA, proteins, and cellular components, altering the cell cycle, leading to carcinogenesis, or causing cell death. https://balancedhealthtoday.com/buy/medicardium-ingredients/ https://balancedhealthtoday.com/medicardium.html

visit maths4ssc.com to download pdf Tainted- दूषित या प्रदूषित/दागी/ ख़राब by uranium: On groundwater contamination- दूषितकरण The groundwater contamination across India must be probed- जाँच-पड़ताल करना, and safe sources identified Reports of widespread- बड़े पैमाने पर uranium contamination- दूषितकरण in groundwater across India demand an urgent response. A study, published in Environmental Science and Technology Letters, has found over 30 micrograms per litre (mcg/l) of the heavy metal in parts of northwestern, southern and southeastern India. Drinking such water can damage one’s kidneys, and the World Health Organization prescribes 30 mcg/l as an upper limit. Unfortunately- दुर्भाग्य से, the residents- निवासी of the regions surveyed were using the contaminated wells- कुओं as their main source of drinking water. These findings highlight a major gap in India’s water-quality monitoring. As the Bureau of Indian Standards does not specify a norm for uranium level, water is not tested regularly for it. This is despite- के बावजूद the fact that evidence- सबूत of uranium contamination has accumulated- संचित from across India over the last decade- दशक. A 2015 Bangalore study, for example, found uranium levels of over 2000 mcg/l in the southern part of the city. Other studies found levels of over 500 mcg/l in Andhra Pradesh and Telangana. The Environmental Science paper adds new data to this body of evidence by sampling- नमूना wells in Rajasthan and Gujarat. The health effects- प्रभाव of drinking uranium-tainted water merit special attention. A few small animal and human studies have found that the heavy metal damages the kidneys. The studies indicate that this is a chemical effect, rather than a radiological one, even though- भले ही uranium is radioactive. But the chronic effects of uranium consumption- सेवन are still- अब तक unknown. Could there be, for example, a link between the high rates of chronic kidney disease (CKD) in India and uranium exposure? In a survey conducted between 2005 and 2010, an Indian registry found 8,385 CKD cases with no known cause. One cluster of mystery- रहस्य disease- रोग, located in Srikakulam district in Andhra Pradesh, has stumped- (of a question or problem) be too hard for; baffle- चकरा देना epidemiologists- a person who studies or is an expert in the branch of medicine which deals with the incidence, distribution, and possible control of diseases. for years. It is impossible to say if these clusters have anything to do with groundwater contamination, unless researchers- शोधकर्ताओं look at it systematically. Another critical area of research is the mechanism by which uranium enters groundwater. The Environmental Science paper identified two types of terrains- क्षेत्रों with heavy contamination. In Rajasthan and other northwestern regions, uranium occurs mostly in alluvial aquifers; while in southern regions such as Telangana, crystalline rocks such as granite seem to be the source. When groundwater is over-extracted from such soils, the researchers suggest, the uranium is exposed to air, triggering its release. These hypotheses- परिकल्पना must be explored- छान-बीन करना, because they will help determine- निर्धारित where to find safer water. This is what happened in West Bengal, where a decade of research revealed- प्रकट why the contaminant arsenic- प्रदूषक आर्सेनिक mainly occurred in shallow- सतही aquifers- a body of permeable rock which can contain or transmit groundwater. Researchers found that a combination of geological and chemical triggers brought arsenic to the Ganga delta in the Holocene era- around 11,000 years ago, and then released it into the sediments- तलछट/ गाद /अवसादों from that period. Similar research across India’s uranium hotspots can uncover who is at risk, and how to protect them.

Mining Equipment Boosts the Technology Innovation of Grinding Machine
More Details : http://www.pakistancrushers.com/contact.php Crushing machine and grinding machine are the important parts in mining machine. The primary crushing is jaw crusher; secondary crushing is impact crusher and cone crusher; the third crushing is sand maker and impact crusher; the last is the grinding machine. The grinding machine is made up of Raymond mill, high pressure hanging roller mill, high pressure micro powder grinding machine, ultrafine powder grinding machine and so on. Large scale grinding machine plays huge roles in the mining, coal, electric power, chemical, building material, metallurgy, water conservancy, construction and highway. They also supply high efficiency and reliable technology for the railway, highway, electric power and municipal works.Therefore, as a basis for countries to establish an independent industry system, mining machine manufacturing industry is also the important symbol for measuring the national industrial strength.As the pillar industry in the national economy, mining machine industry occupies an important place in the economical construction and social development.Through deep research about the current state of the international and national mining machine industry, the rising development tendency of the industry technology especially the frontier technology of grinding machine will be a rare opportunity for the further development and improvement of mining machine manufacturing level. There are two transformations during the development process of the domestic mining machine industry: one is the product development type changes from generic type to independent innovation type.

What is TERBIUM?
What is TERBIUM? Terbium is a chemical element with symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Terbium is never found in nature as a free element, but it is contained in many minerals, including cerite, gadolinite, monazite, xenotime, and euxenite. Swedish chemist Carl Gustaf Mosander discovered terbium as a chemical element in 1843. He detected it as an impurity in yttrium oxide. Yttrium and terbium are named after the village of Ytterby in Sweden. Terbium was not isolated in pure form until the advent of ion exchange techniques. Terbium is used to dope calcium fluoride, calcium tungstate and strontium molybdate, materials that are used in solid-state devices, and as a crystal stabilizer of fuel cells which operate at elevated temperatures. As a component of Terfenol-D (an alloy that expands and contracts when exposed to magnetic fields more than any other alloy), terbium is of use in actuators, in naval sonar systems and in sensors. Most of the world's terbium supply is used in green phosphors. Terbium oxide is in fluorescent lamps and television and monitor cathode ray tubes. Terbium green phosphors are combined with divalent europium blue phosphors and trivalent europium red phosphors to provide trichromatic lighting technology, a high-efficiency white light used for standard illumination in indoor lighting.

Electronics Industry Hazards 1979 Working For Your Life LOHP
At its beginning, more than 40 years ago, the industry seemed "clean," But in 1982, groundwater contamination was discovered throughout Silicon Valley near high-tech manufacturing facilities - toxic chemicals were being leaked out of underground storage tanks. More than 100,000 homes in San Jose were exposed to toxic solvents from a Fairchild computer chip factory. Workers in these facilities were also being exposed to hazardous chemicals on the job., the semiconductors industry has expanded greatly. Due to rapid changes in this industry, manufacturing processes and their associated hazards may change completely every few years. These changes make hazard assessments more difficult to complete and require that they be conducted more often. Common hazards may include exposure to solvents, acid and caustic solutions, toxic metals, and radiation. For more in the hazards in this industry today and in the past, go to the website of the Silicon Valley Toxics Coalition (SVTC) at http://svtc.org/our-work/. The SVTC is a diverse non-profit organization engaged in research, advocacy and grassroots organizing to promote human health and environmental justice in response to the rapid growth of the high-tech industry. The Silicon Valley Toxics Coalition was created in 1982 and composed of high-tech workers, community members, law enforcement, emergency workers and environmentalists. The Coalition pushed for legislation that informed the community of the dangerous chemicals being used in the high-tech factories, and monitored contamination of the area. SVTC was successful in helping create the nation's first legislation for the monitoring of underground chemical storage tanks. The bill was passed in Santa Clara County, CA, leading to similar bills in California State and then at the federal level, This is from the wonderful 1979 film, Working for Your Life (58 minutes, Labor Occupational Health Program) explores the health and safety conditions of America's working women by examining the hazards and demands they face in their workplaces. Andrea Hricko and Ken Light, working for LOHP at the time, created this important documentary film. The film is based on the 1976 handbook - Working for Your Life: A Woman's Guide to Job Health Hazards, by Andrea Hricko with Melanie Brunt. A joint publication of Labor Occupational Health Program and Public Citizen's Health Research Group This handbook is available on the internet at http://content.cdlib.org/ark:/28722/bk0003s5w6s/?layout=metadata . Filmed in over 40 workplaces, this film highlights occupations that are both traditional ones for women (such as clerical and hospital workers) and jobs into which women were just beginning to move (such as mining). The film also shows women who are seeking solutions to these job hazards, including a woman who set up a union health and safety committee, women testifying at OSHA hearings, and a woman organizer who is concerned about health hazards in her electronics plant. A copy of the entire film is also posted to this channel. Thanks to LOHP for permission to post this clip. This description and information are mine and not necessarily the views of LOHP.

Metal Gear Solid 2: 30th Anniversary Remaster Movie [4K 60FPS]
Metal Gear Solid 2: Sons of Liberty holds a special place in my heart. Its story captivated me in ways that few others had, and it showed me how powerful can video games be as an art form. I want fans and newcomers to experience its story in the best way possible, which is why I started this project. This is my way to thank the creators of the Metal Gear franchise and celebrate its third-decade anniversary. This remaster aims to combine the faithful visuals and sounds of the original PS2 version of the game with the high definition tweaks that the HD Collection brought to the PS3 and Xbox 360, while also recreating most of the 2D elements and FMVs from scratch and integrating some new ideas into the Codec conversations. FEATURES ---------------- All cutscenes/gameplay footage were recorded at native 4K 60fps with FXAA and color grading shaders. PS2: 512x448; PS3: 1280x720, 2x MSAA Most FMVs were recreated from scratch in 4K and 60fps. PS2: 512x320; PS3: 1280x720 (mostly upscaled/stretched to 16:9, except in a few rare occasions) The Codec design and presentation were changed. I modified the post-processing filters to make the characters’ faces look sharper and less noisy, and I introduced a few new ideas and concepts. The FMVs used on the Codec calls were also recreated. I used the highest accuracy settings in the PCSX2 emulator to ensure that the visuals are as faithful to the original PS2 version as possible. The HD Collection lacked some post-processing effects like tone mapping and cross-fading; and some elements like the rain drops, Snake’s optic camouflage reflection and particles, and the "heat waves effect" were slightly downgraded. All these issues are absent in the PCSX2 emulator. In order to keep the cinematography and FOVs intact, I rendered all cutscenes in their original 4:3 aspect ratio (with letterboxing), and cropped them to fit the whole screen (~1.85:1). I only used widescreen hacks for the gameplay segments. I used the original PS2 audio files for all the cutscenes and dialogs, as the rest of ports and versions suffer from audio mixing issues. PS2: MS-ADPCM 4 bits & Dolby AC-3 5.1; PS3: [Transcoded] ATRAC3 (Poor mixing on MGS2, MGS3 sounds fine) Subtitles will be included in the video [YOU’LL BE ABLE TO CHOOSE YOUR LANGUAGE WITH THE CC BUTTON] I will try to include as many subtitles as possible, but you are all welcome to contribute adding more languages or fixing mistakes. At the time of writing, the following languages are planned: English [ALREADY INCLUDED] French Russian (Using the translation made by ExclusivE Studio) Spanish I might also add German and Italian subtitles, which are already included in the original game.

Exoplanets: The Quest for Strange New Worlds (live public talk)
Original air date: January 12 at 7 p.m. PT (10 p.m. ET, 0300 UTC) Planets orbiting other stars, or exoplanets, have become an important field of astronomical study over the past two and a half decades. Recent findings from NASA's Kepler mission suggest that nearly every star you see in the night sky probably has exoplanets orbiting it. The number of confirmed exoplanets is now a few thousand. This talk will present a brief history of exoplanet discoveries, the story of the “super-Saturn” extrasolar ring system, and summarize NASA’s ongoing future plans to discover and characterize “strange new worlds.” Speaker: Eric Mamajek, Deputy Program Chief Scientist, NASA Exoplanet Exploration Program, JPL
Waste Incineration - chronic poisoning of the people Part 5 Slag ashes dusts
Lecture with Dr. Harry Rosin 2008 at a congress of the Bürgerbewegung für Kryo-Recycling Slags, ashes, filter dusts http://en.wikipedia.org/wiki/Slag http://en.wikipedia.org/wiki/Ash http://en.wikipedia.org/wiki/Dust http://en.wikipedia.org/wiki/Filter http://en.wikipedia.org/wiki/Flue_gas Even if we believe in the high effency of flue gas cleaning, we have to conclude from the facts described so far (incomplete combustion ( http://en.wikipedia.org/wiki/Combustion ), uncontrollable radicals ( http://en.wikipedia.org/wiki/Free_radicals ), halogenation ( http://en.wikipedia.org/wiki/Halogenation ) with a high degree of toxin formation) that it simply transforms the toxins from gases into solids like slags, ashes and filter dusts. Could that be acceptetd without reservation? Certainly not! Slag of waste incineration plants (WIPs) The WIP lobby likes to label slag "inert", i.e. ecologically compatible and recommends it as high- quality construction material, e.g., for road construction. This is definitely wrong and deveicing! Slags arise in the furmace ( http://en.wikipedia.org/wiki/Furnace ) through partial outgassing ( http://en.wikipedia.org/wiki/Outgassing ) of solids. A crumby, highly porous material remains behind. It becomes separated by passing the grate and is shock cooled with water outside the furnace. In this state the surface of the slag mass really is inert - but only the surface! The inner pores do not consist of vacuum: they are filled with parts of highly toxic flue gas. A reddish- brown slag calles "Marberger Kieselrot" (Marsberg, a smal city in Germany, Nordrhein Westaflen) ( http://en.wikipedia.org/wiki/Kieselrot / http://de.wikipedia.org/wiki/Kieselrot ) that was used to surface running lanes on sport fields has gained notoriety ( 45 ). The original material come from Marsberg ( www.marsberg.de ), where between 1937 and 1945 low- quality copper ores were mixed with rock salt (NaCl) ( http://en.wikipedia.org/wiki/NaCl ) and heated to 600°C to obtain copper concentrate. At the beginning the reddish-brown redidues were deposited on a neighboring slagheap. Later - until 1968 - about 400,000 tons were sold to sport grounds as "Kieselrot". Then it was recognized that slag particles break under the load of sports and under the influence of weathering, allowing emissions of considerable amounts of dioxins ( http://en.wikipedia.org/wiki/Dioxin ). The PCDD/ PCDF content varied between 10,000 and 100,000 nanograms/kg International Toxic Equivalents (I-Eq) ( 45 ) http://en.wikipedia.org/wiki/PCDD http://en.wikipedia.org/wiki/PCDF http://en.wikipedia.org/wiki/International_toxic_equivalent When our WIP- praising, slag- inertization toxicologists were confronted with these and similar facts during public discussions, the only thing they could think of was to recommend vitrification ( http://en.wikipedia.org/wiki/Vitrification ) of slag. Vitrification means bonding slag in solid glass masses before disposal under ground. of course, this idea has long since been "cancelled" as to expansive by the managers who have to ensure the groth of sales of WIPs. Now the slag is simply called "inert" again. It is to be used as base course in road construction. For a certain while this may work without toxic effects. But sillicon oxides ( http://en.wikipedia.org/wiki/Silicon_oxide ) and metal oxides ( http://en.wikipedia.org/wiki/Metal_oxide ) within the slag are unstable and highly reactive when rainwater seeping through defective road surfaces reaches them. Taking this into account, after a legal dispute with the bavarian enviroment ministry in January 1995 a Munich regional court set penalties for use of slag in road construction ( 52 ). Fly ash, filter dusts of waste incineration plants (WIPs) http://en.wikipedia.org/wiki/Fly_ash http://en.wikipedia.org/wiki/Filterdust http://en.wikipedia.org/wiki/Incineration Fly ash and filter dusts generated in WIPs are so rich in heavy metal ( http://en.wikipedia.org/wiki/Heavy_metal_(cemistry) ) and organic toxins that they indisputably can be called "highlly toxic". The contained oganic toxins even include halogenated dioxins/ furans; not just PCDD/ PCDF, but also brominated ( http://en.wikipedia.org/wiki/Bromine ) and fluorinated ( http://en.wikipedia.org/wiki/Fluor ) mixtures generated by catalytic process on metallic surfaces. The intention is to store these long- term poisons in empty undergound salt mines, similar to radioactive waste, but not as expensively packaged. This gives the reason to a long- term toxic problem due to the threat to groundwater (much the same as in the case of nuclear wastes). Consequently, the anti- nuclear movement would have to be an active anti- WIP movement as well. www.atomausstiegselbermachen.de (Energy without nuclear power in Germany) Next chapter: http://sites.google.com/site/kryorecycling/schutz

The brain is the most sensitive. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, inability to have children, and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases anemia, seizures, coma, or death may occur.Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Children are at greater risk as they are more likely to put objects in their mouth such as those that contain lead paint and absorb a greater proportion of the lead that they eat. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically by measurement of the blood lead level. The Centers for Disease Control (US) has set the upper limit for blood lead for adults at 10 µg/dl (10 µg/100 g) and for children at 5 µg/dl. Elevated lead may also be detected by changes in red blood cells or dense lines in the bones of children as seen on X-ray.Lead poisoning is preventable. This includes individual efforts such as removing lead-containing items from the home, workplace efforts such as improved ventilation and monitoring, and nationwide policies such as laws that ban lead in products such as paint and gasoline, reduce allowable levels in water or soil, and provide for cleanup of contaminated soil. The major treatments are removal of the source of lead and the use of medications that bind lead so it can be eliminated from the body, known as chelation therapy. Chelation therapy in children is recommended when blood levels are greater than 40–45 µg/dl. Medications used include dimercaprol, edetate calcium disodium, and succimer.In 2016 lead is believed to have resulted in 540,000 deaths. It occurs most commonly in the developing world. Those who are poor are at greater risk. Lead is believed to result in 0.6% of the world's disease burden. People have been mining and using lead for thousands of years. Descriptions of lead poisoning date to at least 2000 BC, while efforts to limit lead's use date back to at least the 16th century. Concerns for low levels of exposure begin in the 1970s with there being no safe threshold for lead exposure.

What is CHROMIUM TOXICITY? What does CHROMIUM TOXICITY mean? CHROMIUM TOXICITY meaning - CHROMIUM TOXICITY definition - CHROMIUM TOXICITY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Chromium toxicity refers to the fact that chromium is toxic. Water-insoluble chromium(III) compounds and chromium metal are not considered a health hazard, while the toxicity and carcinogenic properties of chromium(VI) have been known for a long time. An investigation into hexavalent chromium release into drinking water was the basis of the true story of Erin Brockovich, dramatised as Erin Brockovich (film). Because of the specific transport mechanisms, only limited amounts of chromium(III) enter the cells. Several in vitro studies indicated that high concentrations of chromium(III) in the cell can lead to DNA damage. Acute oral toxicity ranges between 1900 and 3300 µg/kg. The proposed beneficial effects of chromium(III) and its use in dietary supplements yielded some controversial results, but recent reviews suggest that moderate uptake of chromium(III) through dietary supplements poses no risk. The World Health Organization-recommended maximum allowable concentration in drinking water for chromium (VI) is 0.05 milligrams per litre. Hexavalent chromium is also one of the substances whose use is restricted by the European Restriction of Hazardous Substances Directive. The LD50 for chromium(VI) ranges between 50 and 150 mg/kg. In the body, chromium(VI) is reduced by several mechanisms to chromium(III) already in the blood before it enters the cells. The chromium(III) is excreted from the body, whereas the chromate ion is transferred into the cell by a transport mechanism, one by which sulfate and phosphate ions also enter the cell. The acute toxicity of chromium(VI) is due to its strong oxidative properties. After it reaches the bloodstream, it damages blood cells by oxidation reactions. Hemolysis, and subsequently kidney and liver failure, are the results of this damage. Aggressive dialysis can improve the situation. The carcinogenity of chromate dust has been known for a long time, and in 1890 the first publication described the elevated cancer risk of workers in a chromate dye company. Three mechanisms have been proposed to describe the genotoxicity of chromium(VI). The first mechanism includes highly reactive hydroxyl radicals and other reactive radicals which are byproducts of the reduction of chromium(VI) to chromium(III). The second process includes the direct binding of chromium(V), produced by reduction in the cell, and chromium(IV) compounds, to the DNA. The last mechanism attributes the genotoxicity to the binding to the DNA of the end product of the chromium(III) reduction. Chromium salts (chromates) are also the cause of allergic reactions in some people. Chromates are often used to manufacture, among other things, leather products, paints, cement, mortar, and anti-corrosives. Contact with products containing chromates can lead to allergic contact dermatitis and irritant dermatitis, resulting in ulceration of the skin, sometimes referred to as "chrome ulcers". This condition is often found in workers that have been exposed to strong chromate solutions in electroplating, tanning and chrome-producing manufacturers. In some parts of Russia, pentavalent chromium was reported as one of the causes of premature dementia. As chromium compounds were used in dyes and paints and the tanning of leather, these compounds are often found in soil and groundwater at abandoned industrial sites, now needing environmental cleanup and remediation per the treatment of brownfield land. Primer paint containing hexavalent chromium is still widely used for aerospace and automobile refinishing applications. Overexposure to chromium can occur in welders and other workers in the metallurgical industry, persons taking chromium-containing dietary supplements, patients who have received metallic surgical implants, and individuals who ingest chromium salts. Chromium concentrations in whole blood, plasma, serum or urine may be measured to monitor for safety in exposed workers, to confirm the diagnosis in potential poisoning victims, or to assist in the forensic investigation in a case of fatal overdosage.

CSB Safety Video: Anatomy of a Disaster
Anatomy of a Disaster tells the story of one of the worst industrial accidents in recent U.S. history--the March 23, 2005, explosion at the BP refinery in Texas City, Texas, which killed 15 workers, injured 180 others, and caused billions of dollars in economic losses. The U.S. Chemical Safety Board, an independent federal agency, investigated the accident. The CSB produced this video in March 2008 based on its comprehensive 341-page public report issued in 2007. The video includes a nine-minute animation detailing the events leading up to the blast. It features interviews with members of the CSB investigative team who spent two years studying the causes of the accident. Outside safety experts Prof. Trevor Kletz (Texas A&M University and Loughborough University, UK), Prof. Andrew Hopkins (Australian National University), and Mr. Glenn Erwin (United Steelworkers) provide insightful commentary on the significance of the accident to the world's petrochemical industry. The CSB believes that an understanding of the key findings, recommendations, and lessons from this investigation will help prevent future accidents. To learn more about this and other CSB investigations, please visit CSB.gov.
