Abandoned landfills are a big problem
August 29, 2014 10:30 AM - Alex Peel, Planet Earth Online
Abandoned landfill sites throughout the UK routinely leach polluting chemicals into rivers, say scientists. At Port Meadow alone, on the outskirts of Oxford, they estimate 27.5 tonnes of ammonium a year find their way from landfill into the River Thames. The researchers say it could be happening at thousands of sites around the UK.
Study Suggests More Research before Fracking Continues
August 29, 2014 07:22 AM - ClickGreen Staff, ClickGreen
An independent report on fracking has recommended a temporary moratorium on the controversial process and says that communities should give permission before it can proceed. The interdisciplinary expert panel set up by the Nova Scotia regional government says the science of fracking is relatively unknown and therefore its introduction should be delayed in the Province until the science and its environmental effects are better understood.
Uncontrolled Trash Burning Significantly Worsens Air Pollution
August 26, 2014 04:20 PM - UCAR AtmosNews
Unregulated trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research estimates that more than 40 percent of the world's garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.
How Cutting Emissions Pays Off
August 25, 2014 04:28 PM - Audrey Resutek, MIT News
Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead to reductions in other harmful types of air pollution. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions?
Levels of Air Toxics decreasing across US Cities
August 23, 2014 07:07 AM - Roger Greenway, ENN
More and more people are living in our cities. They are great places to live, exciting, good jobs, great night life, but also sometimes congestion and unhealthy air quality. The latter problems are improving, however. Efforts to make cities livable without driving are paying off. Bike lanes, bike sharing, and efforts to reduce auto traffic and congestion are helping to improve the air quality in our cities. The U.S. Environmental Protection Agency (EPA) this week released its Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. "This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans — preventing illness and improving our quality of life by cutting air pollution - all while the economy has more than tripled," said EPA Administrator Gina McCarthy. "But we know our work is not done yet. At the core of EPA's mission is the pursuit of environmental justice - striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods."
Fracking's Chemical Cocktails
August 22, 2014 09:15 AM - Tim Radford, The Ecologist
Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told the American Chemical Society meeting in San Francisco that they scoured databases and reports to compile a list of the chemicals commonly used in fracking.
NASA reports unknown source of banned ozone-destroying compound
August 21, 2014 07:33 AM - ClickGreen Staff, ClickGreen
NASA research has revealed the Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012.
Toxic Algae Scare Prompts Backlash Against Farms
August 18, 2014 09:25 AM - S.E. Smith, Care2
What do a no-drink order in Toledo and a backlash against factory farming have in common? A lot, as it turns out. Residents of Ohio's fourth-largest city were advised for multiple days earlier this month to refrain from drinking their tap water because it had been contaminated by toxic algae. As residents struggled to deal with their contaminated water supply, the culprit behind the problem became readily apparent: factory farms. The Ohio Agriculture Advisory Council (OAAC) is proposing a regulatory crackdown that could forever change industrial farming practices in this Midwestern state.
Water quality alerts do not seem to deter some surfers
August 16, 2014 07:23 AM - Oregon State University
Nearly three in 10 surfers admit they knowingly surf during health advisories — nearly the same amount that chooses not to surf during periods of elevated bacteria. About 40 percent of surfers said they were unaware if they had ever surfed during an active health advisory. The data can help public officials better warn surfers of potential health risks, said Anna Harding, co-author of the study and professor in OSU's College of Public Health and Human Sciences. "Beach advisories for bacteria are not having their intended effect of dissuading surfers," Harding said. “The lack of awareness about advisories — and willingness to take risks surfing in water that may be contaminated — suggests the need to educate surfers about behaviors that make them vulnerable to illness."
The cost of marine debris
August 12, 2014 03:53 PM - NOAA
Marine debris has many impacts on the ocean, wildlife, and coastal communities. A NOAA Marine Debris Program economic study released today shows that it can also have considerable economic costs to residents who use their local beaches. The study found that Orange County, California residents lose millions of dollars each year avoiding littered, local beaches in favor of choosing cleaner beaches that are farther away and may cost more to reach. Reducing marine debris even by 25 percent at beaches in and near Orange County could save residents roughly $32 million during three months in the summer.
