Learn more about PBDEs in the coastal zone from Dr. Gunnar Lauenstein, Mussel Watch Program manager.
Globally, thousands of new chemicals are engineered each year. Most will find their way into coastal, marine and Great Lakes waters of the United States with unknown consequences to these environments and to the millions of Americans who live along our shores. Many of these chemicals have been labeled as “Chemicals of Emerging Concern” (CEC) by scientists around the world, and include agro-chemicals, pharmaceuticals, personal care products, and a wide range of industrial products such as flame retardants, including Polybrominated Diphenyl Ethers (PBDEs).
This report was developed by NOAA's National Status & Trends Program (NS&T), and represents the first national assessment of PBDEs in the U.S. coastal zone. Results suggest that they are widely distributed nationally. Several regions, including the northern Mid-Atlantic, central Gulf of Mexico, Southern California, Pacific Northwest and the Great lakes have elevated PBDE concentrations compared with other coastal regions. Furthermore, PBDE concentrations are positively correlated with human population density along the U.S. coastline. The national and regional perspectives provided herein are intended to support research, local monitoring, and to assist resource managers and policy makers tasked with making regulatory decisions about these contaminants.
