Polybrominated Diphenyl Ether in the Lake Superior Watershed

The Minnesota Pollution Control Agency (MPCA) proposes to assess the   prevalence, potential for local sources and accumulation trends of   Polybrominated diphenyl ethers (PBDEs) in the St. Louis River Area   of concern and western Lake Superior watershed. PBDEs are widely   used as flame retardants and are environmentally persistent and   bioaccumulative. Recent studies have shown that they are ubiquitous   environmental contaminants in marine and freshwater environments. A   Swedish trend study has estimated that concentrations of PBDEs in   human milk have increased exponentially between 1972 and 1997. An   assessment of PBDEs in the Western Lake Superior watershed and St.   Louis River Area of Concern has not been conducted until now. This   project will estimate the prevalence of PBDEs in surficial sediments   and fish from the western arm of Lake Superior, the St. Louis River   Area of Concern and an ambient lake in the Lake Superior watershed.   Trends in PBDE accumulation in ambient and industrially-impacted   locations will be examined by analyzing sediment cores from a remote   lake and the Duluth-Superior Harbor.     (PBDE); (PBDE's); (PBDEs); (Polybrominated Diphenyl Ether);   (Polybrominated Diphenyl Ethers); (AOC); (area of concern); (flame   retardants); (flame retardant); (POP); (POP's); (POPs); (persistent   organic chemical); (persistent organic chemicals); (toxic organic);   (toxic organics)
