Title: Temporal trends in organic contaminant bioaccumulation in Boston Harbor

Abstract

Since 1987 the MWRA has used in situ caged mussels (Mytilus edulis) to assess organic contaminant (PAHs, PCBs, organochlorine pesticides) bioaccumulation resulting from the primary treatment discharge of its Deer Island POTW. Results indicate a substantial reduction in many contaminants, most notably the Low Molecular Weight (petrogenic) PAHs which are clearly associated with the Deer Island discharge. NOAA `Mussel Watch` and other fish tissue contaminant data are used to support the observation of these decreases. Effluent water quality data and concurrent mussel body burden data from dirty and clean control sites are used to interpret the trends and elucidate the contamination sources. During the same time frame histopathological analyses of winter flounder collected in proximity to the Deer Island discharge have shown a marked reduction in liver lesions and other contaminant related diseases. More recently (since 1992) slight elevations in chlordane, dieldrin, and total DDTs have been noted in mussel, flounder, and lobster tissue collected from Boston Harbor and Massachusetts Bay. The authors discuss the possibility that remobilization of contaminants from the sediments may be a source of this apparent increase.
