Biomarker response and hypothalamus-pituitary-interrenal axis functioning in Arctic charr from Bjørnøya (74°30'?N), Norway, with high levels of organohalogenated compounds.
The populations of Arctic charr (Salvelinus alpinus) residing in Lake Ellasj?en at Bj?rn?ya Island in the Norwegian Arctic (74? 30'N, 19? 00'E) possess substantially higher levels of organohalogenated compounds (strongly dominated by polychlorinated biphenyls, PCBs) than conspecifics residing in other, proximate lakes on the island. In the present study we sampled large (
