Levels of Polychlorinated Biphenyls (PCBs) and Three Organochlorine Pesticides in Fish from the Aleutian Islands of Alaska

Abstract: BackgroundPersistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs) and chlorinated pesticides, have been shown to have many adverse human health effects. These contaminants therefore may pose a risk to Alaska Natives that follow a traditional diet high in marine mammals and fish, in which POPs bioaccumulate.Methods and FindingsThis study examined the levels of PCBs and three pesticides [p, p′-DDE, mirex, and hexachlorobenzene (HCB)] in muscle tissue from nine fish species from several l… Show more

“…The few cases of land mammals in the Aleutians currently targeted by federal managers for removal are a subset of conditions in a broader region that contends with subsistence access issues, environmental risk to foods, and high shipping and travel costs to obtain food [4][5][6][7] but generally enjoys a variety of abundant wild foods [8] for those with time, skills, equipment, health status, and income sufficient to support a hunting and fishing lifestyle. Introduced land mammals are significant components of the abundance and diversity available.…”

“…The maximum concentration was recorded from pink (215 ng/g lipids) that is higher than the value for pink from the other Pacific coast (Figure 2). In salmon, the same as in other species collected off North America, the DDE metabolite always dominates [18,19]. As we showed earlier, the total concentration of HCHs in marine organisms from the the Sea of Japan, the Sea of Okhotsk and the Bering Sea, as a rule, is higher than the DDT content [5,9,10,[20][21][22][23].…”

“…Thus, HCH concentrations in bottom sediments of Lake Baikal were 3 times as high as the DDT level [28]. In salmon, high concentrations of pesticides including DDE are recorded more frequently as compared to those in other fishes of the North Pacific such as cod, flounder, greenling, and some others [18]. This difference is explained mostly by the wide range of salmon's feeding migrations, by presence of fish predominantly in the upper pelagic zone where atmospheric precipitations concentrate, as well as by high fattiness of salmon.…”

“…When in contact with water they also will be transported to planktonic organisms, entering the food chain. POPs were found as contaminants in birds (Chen and Hale, 2010;Vorkamp et al, 2009), penguins (Corsoloni et al, 20060, fish (Ondarza et al, 2011;Hardell et al, 2010), sea lions (Alava et al, 2011), among others.…”
