'Cost of Coal' explores life cycle of the rock and its effects on human health in W.Va., Mich. and Nev.

The Sierra Club has partnered with award-winning photojournalist Ami Vitale to produce a photographic essay for its magazine about the life cycle of coal and its effects on the lives of residents living close to mine sites, power plants and coal-waste disposal areas, most of which are in rural areas.

"Cost of Coal" includes an 18-page photo spread in the November/December issue of Sierra, and an interactive website with more than 100 photos and videos of individuals living near four sites impacted by coal: Blair, W.Va., Lindytown, W.Va., River Rouge, Mich., and near the Moapa Band of Paiutes Reservation in Moapa, Nev. Slide shows and videos are organized by location and story on the website, where readers can donate to the Sierra Club's Beyond Coal campaign, Living Green Magazine reports.

Here's a video overview of the project:

Physicians for Social Responsibility say 'each step of the coal life cycle impacts human health'

A new report released this week analyzes the human health impacts of coal, with a specific focus on the cumulative impacts of air pollution from burning coal on the respiratory, cardiovascular and nervous systems. The Physicians for Social Responsibility study, "Coal's Assault on Human Health," concluded that "each step of the coal life cycle -- mining, transportation, washing, combustion and disposing of post-combustion waste -- impacts human health."

Researchers found that mining of coal contributes to heart disease, cancer, stroke and chronic respiratory diseases, four of the five leading causes of death in the U.S. In particular, burning coal contributes to diseases affecting large portions of the U.S., including asthma, lung cancer, heart disease and stroke. It also impairs lung development, increases heart-attack risk and hinders intellectual development. The report adds to previous correlation studies suggesting possible links between mountaintop mining and increased rates of disease in Appalachia by University of West Virginia public-health professor Michael Hendryx.

Physicians for Social Responsibility makes several recommendations, including reducing carbon dioxide emissions "as deeply and as swiftly as possible," ending construction of new coal-fired power plants, reduction of fossil fuel use and the development of renewable energy sources. (Read more)

Heavily obese states have large rural populations

At least 30 percent of adults in 12 states are considered obese, according to Centers for Disease Control and Prevention data. Previously, only nine states had such high obesity rates. More than one third of adults, and almost 17 percent of youth, were obese in 2010.

Most of the states have relatively large rural populations. Mississippi had the highest rate at almost 36 percent. (Read more)

Federal agency finds elevated levels of problematic substances in air, soil and water near strip mines

After a year of testing air, water and soil around mountaintop removal mine sites in Central Appalachia, the U.S. Geological Survey has found high levels of toxins in the soil and water, concluding that people in southern West Virginia living close to these sites are living in an environment "with significant chemical discrepancies from the rest of the state," reports Alice Su of The Center for Public Integrity. The findings are the first conclusive scientific evidence by a federal agency that mountaintop removal mining could cause human health risks.

USGS research geochemist Bill Orem, the principal investigator, said water in mining areas had unusually high acid and electrical conductivity levels in the water, air had abnormal levels of particulates, and soil and streams had irregular levels of polycyclic aromatic hydrocarbons. "Several PAH compounds are probable or possible human carcinogens," Su notes. Orem said results are preliminary and research is still being conducted, but soil samples from mining areas were "certainly different" from those in non-mining areas, and that airborne silica particles, known to cause lung disease, were "definitely higher."

Orem said the USGS will be "prudent" to connect preliminary data to actual health problems in the region that have been documented in controversial correlation studies by West Virginia University public health professor Michael Hendryx. "You have to be conservative in your statements," Orem said. "It can't be driven by people's feelings. It has to be a scientific, data-driven process." (Read more)

New book focuses on Appalachian health

A new book, which compiles health reviews and studies from the 13-state Appalachian region, reveals greater health care disparities between counties within the region than between Appalachia and the rest of the U.S.

Kevin Kavanagh reviewed Appalachian Health and Well-Being for The Courier-Journal, and reports that the rural Central Appalachia region is "extensively discussed" in the book as having some of the nation's highest rates of poverty, tobacco and drug use, obesity and diabetes.

"The vast majority of the chapters are a well-written, comprehensive discussion of the problems affecting Appalachia," Kavanagh writes. "An important concept is that unhealthy lifestyles are not just the patient's fault, but also a social problem; making substantial headway requires improvement in poverty, education and employment."

The book, edited by Robert Ludke and Phillip Obermiller of the University of Cincinnati, is available from the University Press of Kentucky.

Humane Society tells 51 pork producers it will sue, alleging failure to report environmental violations

The Humane Society of the United States plans to sue 51 pork producers in North Carolina, Iowa and Oklahoma for alleged unreported ammonia releases. The organization said it identified the producers "after months of research," and said they release hundreds of pounds of ammonia each day. The research methods used to determine this were not revealed.

HSUS is sending letters of notice to producers affiliated with the National Pork Producers Council, which represents the U.S. pork industry, Rod Smith of Feedstuffs reports. The groups acknowledged that some producers are "attentive" to animal welfare and environmental issues, but some of the wealthiest "apparently refuse to comply" with public health laws. NPPC said HSUS is not alleging environmental harm, but paperwork violations. (Read more)

Mostly Republican governors want to opt out of health care law's Medicaid expansion

When the U.S. Supreme Court declared yesterday that the Affordable Care Act is constitutional, it limited the federal government's power to make states expand their Medicaid programs, which will likely impact the implementation of the law in several states, especially those controlled by Republicans.

Medicaid expansion was challenged by 26 states as being "coercive" because it would have allowed the feds to take back all of a state's Medicaid funding if it refused to comply. But the court ruled that the U.S. Government can only take back funding designated specifically for expansion, and not any of a state's existing Medicaid funding. "What Congress can not do is to penalize states that choose not to participate in that new program by taking away their existing Medicaid funding," Chief Justice John Roberts wrote for the majority.

States stand to gain a lot by expanding the program, Christine Vestal of Stateline reports, because the federal government pays 100 percent of costs for the first two years, then reduces its funding to 90 percent in 2020. The Congressional Budget Office estimates this would add up to a $20 billion transfer to states over the first 10 years of expansion. But, some states say covering 10 percent of the cost of new beneficiaries would put more strain on their budgets. (Read more)

Most Republican-led states have done little to set up online exchanges which allow residents to compare private health insurance for the best price and serve as a portal for joining Medicaid expansions, The Associated Press reports. State have to tell the federal government in November whether or not they will build exchanges. The federal government will build a common exchange for states that don't build their own.

Wisconsin's Republican Governor Scott Walker denounced the law on Thursday, saying he would not implement any parts of it in Wisconsin before the presidential election. "While the court said it was legal, that doesn't make it right," Walker said. "For us to put time and effort and resources into that doesn't make a lot of sense."

GOP leaders in Mississippi say they don't have the money to expand Medicaid. Emily Wagster of AP reports Mississippi receive a large chunk of federal money for Medicaid because it has a high percentage of low-income residents. Republican Governor Phil Bryant said deep cuts in education and transportation would have to be made to cover the cost of Medicaid for more than 400,000 additional people. He said the state is looking at "some leeway in the decision to not penalize states for not complying with Medicaid requirements."

The question of Medicaid expansion is still up in the air in several other Republican-controlled states, including Nebraska, Ohio, South Carolina and Indiana, where governors say they would be hard-pressed to implement it. But Washington Republican Attorney General Rob McKenna, who joined the lawsuit against the Affordable Care Act last year, split with most of the GOP and said Congress shouldn't repeal the law, or any of its provisions, including the individual mandate. McKenna, who's currently running for governor, said he's ready to implement health-insurance exchanges and Medicaid expansion if elected, Jim Brunner of The Seattle Times reports.

CDC says 4% of Central Appalachian surface miners tested have black-lung disease

Though the study didn't test Kentucky separately from the 14 other states assessed, Laura Ungar of The Courier-Journal in Louisville asked about it and found that "13 of 230 Kentucky surface miners tested — or 5.7 percent — had black lung," she reports, quoting Cara Halldin, a CDC epidemic intelligence service officer, as calling that number " a disproportionate burden."

It's not clear why the incidence is higher in Central Appalachia than other parts of the country, but Halldin suspects it has to do with "more years spent mining, area geology or the safety culture at mines," Ungar reports. One study showed miners who work in Central Appalachia typically work 28 years in the mines while non-Appalachian miners work average 20 years.

Black-lung disease, or coal workers' pneumoconiosis, is the result of miners repeatedly inhaling the dust that comes from extracting coal. That dust occurs whether the miner is under- or above-ground. "Coal mining is really, really dusty. Don't matter what you do, you're in the dust," said John Bud Ritchie, a retired surface miner who has black lung disease. "It's real rough. You can't hardly keep the dust down on hot days."

The federal exposure limit for "respirable dust" in underground and surface mines is 2 milligrams of coal dust per cubic meter of air. That limit was set in 1969, along with a law that set up "a surveillance system for assessing prevalence of black lung among underground coal miners," Ungar reports. "But the requirement for surveillance doesn't extend to surface miners." Haldin said, "Industry should recognize this is a problem and their workers are at risk and bring down the levels."

In the wake of the CDC study, the National Institute for Occupational Safety and Health is offering free black-lung screenings in Eastern Kentucky, Hazard, Ky.'s WYMT-TV reports. The screenings will be at various locations in Eastern Kentucky throughout the summer and will be confidential. They will include a work history questionnaire, chest X-ray and a spirometry test, with the whole process lasting about 25 minutes. NIOSH will provide participants with results of their screenings, and will not release information to the public or give it to coal companies. For a list of when and where the screenings will take place, click here. 

Ex-secretaries of agriculture, health offer bipartisan plan to fight obesity epidemic, other health woes

Four former secretaries of heath and agriculture and the Bipartisan Policy Center have released a lengthy report aimed at the nation's obesity epidemic. With 26 recommendations, the report promotes public and private sectors working together to create healthy families, schools, workplaces and communities.

The report, called "Lots to Lose," recommends extending federal guidelines for diet and physical activity to all children under 6 years old, along with offering more support to promote breastfeeding. "Learning to be active and staying active is a critical piece of the puzzle," said Republican Mike Leavitt, former secretary of health and human services and former governor of Utah. "Government has a role to play, but it is not the answer."

"If you think this is fluffy stuff about diet and exercise or about creating a nanny state you are wrong," said Dan Glickman, who was a Democratic congressman from Kansas and agriculture secretary under Bill Clinton. "Americans like silver bullets to solve problems. This one requires silver buckshot."

Former agriculture secretary Ann Veneman, a Republican who served under George W. Bush, spoke of the importance of good nutrition during the first 1,000 days of a child's life. "Improving health outcomes early in life is a critical element in helping to shift our current health care system toward prevention," she said.

Democrat Donna Shalala, president of the University of Miami and health secretary under Clinton, also participated. While The Washington Post's Janice D'Arcy called the report "an earnest and comprehensive effort," she asked, "Haven't we been down this road before?" For the report, click here.
