We report here on the distributions of several chlorobiphenyls In samples of water, sediment and biota of the Acushnet River Estuary - New Bedford Harbor, Buzzards Bay, Massachusetts, U.S.A. Our general objective Is to gain Information of generic utility In addition to providing specific data and Interpretations of assistance to remedial action at this Superfund site. Our specific objectives In this paper are to 1) document the composition of Individual chlorobiphenyls In biota normally harvested by commercial and recreational fishermen and discuss factors which could lead to the observed distributions and potential Implications for public health standards for PCBs In fish and 11) to Investigate, In a preliminary manner, the adherence of bloconcentratlon of PCBs to predictions based on equilibrium assumptions and octanol/water (Kg ) partition coefficients (, 22). 

Interlaboratory coefficients of variation of chlorobiphenyls and organo-chlorine pesticides in sediments are about 40%, those in cod liver oil, about 26% [134].

The chlorobiphenyls are chemically related compounds with a wide range of physicochemical properties such as vapour pressure, water and lipid solubility, and particle/solution distribution coefficients. They can thus be used as model compounds to forecast the behaviour and distribution of other, less well studied organics. The CB distribution patterns can be used as a basis for theoretical models to evaluate the reliability of experimentally determined distribution patterns of a variety of compounds.
