How Pollutant Risk is Affected by Different Insect Stages
September 5, 2014 11:34 AM - Editor, ENN

The food chain is a hierarchical series of organisms that are interrelated in their feeding habits. The chain starts when the smallest being like an insect is fed upon a larger prey species, which in turn feeds an even larger species. So if a species among the lower ranks of the chain has accumulated toxins such as pesticides or other organic chemicals, there is potential for these toxic substances to affect the species that prey upon them. This is the subject of new research conducted by the US Geological survey that found when fish feed on insects and when other wildlife species feed on fish, harmful contaminants are transferred up the line.

New way to remove greenhouse gases from the atmosphere
September 4, 2014 07:01 AM - Institute for Integrated Cell-Material Sciences, Kyoto University, via EurekAlert

Researchers in Japan have engineered a membrane with advanced features capable of removing harmful greenhouse gases from the atmosphere. Their findings, published in the British journal Nature Communications, may one day contribute to lower greenhouse gas emissions and cleaner skies. Greenhouse gases, originating from industrial processes and the burning of fossil fuels, blanket the earth and are the culprits behind current global warming woes. The most abundant among them is carbon dioxide, which made up 84% of the United State's greenhouse gases in 2012, and can linger in Earth's atmosphere for up to thousands of years.

Innovative Recycling Program Turns Bottles Into Subway Rides

Forget your reusable bottle at home this morning and find yourself towing an unwanted plastic bottle? If you are in Beijing, you are in luck — you could trade in that empty bottle for a subway ticket. "Reverse vending machines" in subway stations around the city allow riders to deposit polyethylene terephthalate (PET) plastic bottles in exchange for a commuter pass or mobile phone credit.

Office Plants Increase Productivity by 15%

Do you have any plants in your office? What about at home? It may take a green thumb to keep these potted floras alive and well, but studies show that indoor plants have multiple benefits and are worth the care and attention. Some benefits include helping us breathe easier, purifying air and improving health, and even sharpening our focus. According to a new study, plants can even make work environments more productive. Researchers claim that 'green' offices with plants make staff happier and more productive than 'lean' designs stripped of greenery.

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

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.
