Dioxin and furan concentrations were measured in crabs collected from eleven areas of potential chemical contamination and one reference area in Puget Sound in the spring of 1991. While recreationally harvestable Dungeness crabs were the target species, red rock and graceful crabs were also analyzed because they were the only species which could be collected in some areas. Both crab muscle and hepatopancreatic tissues were analyzed for the presence of dioxins and furans. The results of these analyses were evaluated using EPA's human health risk assessment guidance. While dioxins and furans were present in low concentrations in all samples, it appears that only the very heavy consumer of crab muscle and hepatopancreas would see a very sizeable increase in the risk of developing cancer from these chemicals.
