EPA adds 23 chemicals, including BPA, to key list for scrutiny, possible action
Bloomberg
The Environmental Protection Agency has added 23 chemicals—including bisphenol A, seven phthalates and two flame retardants—to a key list of chemicals that will have particular uses carefully scrutinized for possible regulation or other controls. The agency on Oct. 23 updated the list of chemicals in commerce that meet certain criteria, such as being used in children's products or being carcinogenic, persistent in the environment or harmful to development, reproduction or the neurological system.

Tracking sea turtles as they swim for their lives
The New York Times
When loggerhead turtles hatch on the beach of Boavista, the easternmost of the Cape Verde islands, they head for the water to begin what biologists call a swimming frenzy. The beach and coastal waters are full of predators, and the babies are tasty, nutritious and defenseless. They need to reach ocean currents as quickly as they can, to be carried to less dangerous waters. This is the pattern of baby sea turtles in general, and scientists have had a good idea of what currents they ride. But they haven’t had a reliable way to track the turtles’ swims and see exactly how they manage their first hours.

Steamworks and upstart Yellow Dog lead the way in the BC Beer Awards
The Green Man
Yellow Dog Brewing Co. – metro Vancouver's youngest microbrewery at just three months – showed well against the big dogs, grabbing the Best in Show for Shake A Paw Smoked Brown Porter in the BC Beer Awards. Shake A Paw bested 465 entries to take top honors.

Study: BP spill left 'bathtub ring' of oil across more than 1,200 square miles of Gulf seafloor
NOLA
Scientists have found evidence of a "bathtub ring" of oil particles from the BP Deepwater Horizon spill covering more than 1,200 square miles of the Gulf of Mexico's seafloor, according to a study published online in the Proceedings of the National Academy of Sciences. A team of scientists with the University of California-Santa Barbara, University of California-Irvine, and the Woods Hole Oceanographic Institute tested more than 3,000 samples of sediment taken from 534 locations in the Gulf for the chemical hepane, a constituent of crude oil that was found in the oil released from BP's Macondo well.

Methane emissions may swell from behind dams
Scientific American
Imagine nearly 6,000 dairy cows doing what cows do, belching and being flatulent for a full year. That's how much methane was emitted from one Ohio reservoir in 2012. Reservoirs and hydropower are often thought of as climate friendly because they don't burn fossil fuels to produce electricity. But what if reservoirs that store water and produce electricity were among some of the world's largest contributors of greenhouse gas emissions?

Plastic nanoparticles also harm freshwater organisms
Phys.org
Organisms can be negatively affected by plastic nanoparticles, not just in the seas and oceans but in freshwater bodies too. These particles slow the growth of algae, cause deformities in water fleas and impede communication between small organisms and fish. These are the results of research carried out by Wageningen University and IMARES, part of Wageningen UR, published in the latest issue of Environmental Science and Technology. It is the first time that such effects of plastic on freshwater organisms have been studied.

Oceans could lose $1 trillion in value due to acidification
Scientific American
The U.N. Convention on Biological Diversity released a report updating the impacts of ocean acidification on marine life. This time, it put estimated costs on the predicted damage, hoping to make governments aware of the potential size of the various threats. While many of the effects of growing acidification remain invisible, by the end of this century, things will have changed drastically, the report found. One estimate looking only at lost ecosystem protections, such as that provided by tropical reefs, cited an economic value of $1 trillion annually.

Critics of Dow herbicide ingredient sue US EPA over approval
Reuters
A coalition of U.S. farmer and environmental groups filed a lawsuit seeking to overturn regulatory approval granted for a herbicide developed by Dow AgroSciences. The lawsuit, filed in the U.S. Court of Appeals for the Ninth Circuit in California, argues that the Environmental Protection Agency did not adequately analyze the impact of one of the new herbicide's active ingredients, 2,4-D, before granting approval on Oct. 15 to Dow's Enlist Duo herbicide.
