Chemicals

"BP succeeded in sinking the oil from its blown well out of sight — and keeping much of it away from beaches and marshes last year — by dousing the crude with nearly 2 million gallons of toxic chemicals. But the impact on the ecosystem as a whole may have been more damaging than the oil alone."

"The Supreme Court decided [Tuesday] not to take up the question of whether U.S. EPA followed the correct procedure in effectively banning a pesticide that had been in use for years."

"The U.S. Forest Service is weighing tighter restrictions on aerial fire retardant drops as part of a long-running legal battle over the environmental effects of pouring millions of gallons of the chemical mixture on Western wildlands every year.

Retardant use has soared in recent decades as wildfires have grown larger and more houses have been built on the wildland edge. Nationally, federal and state agencies apply an average of more than 28 million gallons a year, the vast majority of it in the West and much of that in California.

Nearly a third of the retardant used by the Forest Service in the last decade has been in California, where urban development abuts fire-prone wildlands and weather and terrain regularly produce monster blazes.

The proposed limits, outlined in a recently released environmental document, are not expected to cut overall usage. Rather, they are intended to reduce drops on and near waterways, where they can kill fish, and to slightly expand the acreage that is off limits to retardant releases for ecological reasons."

Bettina Boxall reports for the Los Angeles Times May 30, 2011.

"The proposed limits are intended to reduce drops on and near waterways, where they can kill fish, and to slightly expand the acreage that is off limits to retardant releases for ecological reasons."

"Federal chemists have confirmed what everyone had expected: that if a bisphenol-A-based resin is used to line most food cans, there’s a high likelihood the contents of those cans will contain at least traces of BPA. A hormone-mimicking compound, BPA is the monomer — or chemical building block — used in making the resin."

"Saying innovation is being stifled and research costs are being unnecessarily increased, S.C. Johnson & Son Inc. wants the Environmental Protection Agency to ease its rules on protecting human subjects in pesticide research."

"Members of Congress are asking the Food and Drug Administration to issue a voluntary recall of two hair-straightening treatments sold in salons under the brand name Brazilian Blowout, citing concerns about unacceptably high levels of formaldehyde, a suspected carcinogen."
