Presentation Abstract

In 2014, King County initiated a long-term monitoring program of marine tissue contaminants. The program monitors important prey of marine mammals and species collected for human consumption: Dungeness and Red rock crab, English sole, market squid, and rockfish (brown, copper, and quillback). Sampling locations include Elliott Bay and central Puget Sound sites within King County waters. Generally, PCB concentrations in all species were higher in Elliott Bay compared to other King County locations. With a few exceptions, PBDE concentrations in all species generally exhibited less of a distinct geographical pattern than was observed for PCBs. Contaminant data for Puget Sound squid is limited. The data collected by this effort represent one of the few contaminant data sets available for market squid tissue. PCBs and PBDEs were detected at relatively low concentrations in squid tissue. For crab, differences in accumulation of mercury and PCBs in the hepatopancreas and muscle tissue were observed. Crab, English sole, and rockfish will continue to be monitored by King County’s marine tissue monitoring program. This presentation will summarize the spatial differences in PCB and PBDE concentrations between species.

Spatial comparison of PBTs in marine fish and invertebrates from King County waters
