Organochlorines and Heavy Metals in Seals and Birds from the Weddell Sea

International Journal of Biology, Vol. 2, No. 1, January 2010, all in one file

“…These levels indicate that brown skua lives on cadmium-rich diet. The results follow the distribution pattern in the closely related South polar skua (Catharacta maccormici) (Schneider at al., 1985) -kidney > liver > muscle. Karasawa and Mishima (1981) obtained very low values in skua muscles from East Antarctica.…”

“…As in the case of Cd the concentrations of Cu and Zn were the highest in liver and kidney. Several authors have reviewed levels of metals in seals, however relatively few (Schneider et al, 1985;Steinhagen-Schneider, 1986) have reported the concentration of metals in crabeater seals organs and tissues. They obtained much higher concentration of Cd in liver and kidney in crabeater seal from Weddell Sea.…”

“…The levels of essen ti al metals, such as Cu and Zn are metabolically regulated in seabird tissues (Schneider et al, 1985). Levels of Cu in all seabird species examined, except Common eider and King eider, were very similar and near a mean 20 mglkg.…”

“…HCH higher concentrations were reported in specimens of Weddell seal and elephant seal (Mirounga leonina). Schneider et al (1985) Due to ice coverage the temperature of the Arctic Ocean is close to freezing point year round. Surface water salinities vary between 30-33 in the Arctic Ocean.…”
