A study was begun in 1975 by the New Jersey Department of Environmental Protection (NJDEP) to monitor the concentration of PCBs in fish from the estuarine and coastal marine waters of New Jersey (Kennish and Ruppel 1996). The NJDEP monitored the concentration of PCB congeners exclusively found in Aroclorsl248, 1254, and 1260. Although their studies indicate that PCB contamination is highest in the Hudson-Raritan estuary, there is evidence that PCB concentrations are declining in some fish species. Eor example, the mean PCB level for striped bass and white perch decreased from 2.14 to...

Fig. 16. Bioaccumulation factor (normalized to organism lipid and sediment organic carbon) as a function number of aromatic rings in PAHs. Mean and standard error of the mean BAFi c for PAHs consists of 2-6 aromatic rings. Each mean represents several PAHs and sediments (sites = 7 for amphipod = 5 for polychaete). [See Table 1 for PAHs and ring categories.] Polychaete (Armandia brevis) and amphipod (Rhepoxynius abronius) individuals were exposed to Raritan-Hudson estuary (New York) sediments for 10 d. See Appendix for BAFioc definition. (Data from Meador et al. 1995.)...
