Concerns raised about coastal levels of flame-retardant chemicals

U.S. study finds widespread, high concentrations near Southern California and Chicago, as well as Alaska.

Flame-retardant chemicals that have been linked to reproductive and neurological problems in animals have seeped into coastal environments even in remote regions and have been found in high concentrations off populated areas such as Chicago and Southern California, a federal study revealed Tuesday.

“This is a wake-up call for Americans concerned about the health of our coastal waters and their personal health,” said John H. Dunnigan, assistant administrator of the National Ocean Service, a branch of the National Oceanic and Atmospheric Administration, which released the report.

The study, part of the Mussel Watch Program, was the most comprehensive look at the nationwide presence of chemicals called polybrominated diphenyl ethers, used in a variety of commercial goods since the 1970s as a fire retardant.

High levels of the chemicals were found in sediment and shellfish samples in areas including the Pacific Northwest’s Puget Sound; the Tampa-St. Petersburg, Fla., coast; New York’s Hudson-Raritan Estuary; Lake Michigan off Milwaukee, Chicago and Gary, Ind.; and off remote shores in Alaska. The highest concentrations were near industrial centers.

The new report builds on a 1996 study that reported levels of the chemicals in limited areas.

    If we don't change our ways soon...

    A new report by the Royal Society, chaired by Nobel prize-winning biologist Sir John Sulston warns that world population must be stabilized and consumption in wealthy nations must be reduced or the entire planet is in big trouble. As the report reads: "The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future."
    This is the same warning that President Jimmy Carter gave Americans back in the 1970's - but it was ignored when Ronald Reagan came to power with a "more positive" message basically telling Americans we can do whatever we want. And then after 9/11 - Bush told us all we should go shopping and consume ever more.
    And now with corporations calling the shots in Washington - long-term sustainability of the planet takes a back seat to short-term profits. If we don't change our ways soon - and embrace clean, alternative energy and educate women around the plant - then we all could be headed for a rough century.
