Abstract

Organochlorine pesticides are persistent toxic substances of anthropogenic origin that affect biota. Hexachlorocyclohexane (HCH) isomers (α-, β-, and γ-), DDT and its metabolites (DDD and DDE) were detected in five individuals of fulmars Fulmarus glacialis Linnaeus, 1761 from the coast of Eastern Kamchatka and the Kuril Islands. The average amount of HCH isomers in the organs of fulmars ranged from 608 ± 177 ng/g lipids in the total homogenate of the organs to 2093 ± 264 ng/g lipids in the feathers with skin. The average range of the amounts of DDT and its metabolites was from 3606 ± 333 ng/g lipids in the feathers with skin to 4076 ± 1624 ng/g lipids in the feathers. The results are discussed.
