| Abstract |
Sum of chlordane compounds ( Sigma CHL; cis-chlordane + trans-chlordane + cis-nonachlor + trans-nonachlor + oxychlordane) are concentrated gradually with trophic levels from zooplankton to Dall's porpoise (Phocoenoides dalli ) through squid and fish. The order of bioconcentration factors (BCF : concentration in organism/concentration in seawater) in these organisms was Sigma DDT (p,p'-DDE + p,p'-DDD + p,p'-DDT)> Sigma CHL less than or equal to PCBs> Sigma HCH ( alpha -HCH + beta -HCH + gamma -HCH). Calculation for the concentration factor against food, namely biomagnification factor (BMF: concentration in organism/concentration in its food), was made for Dall's porpoise and thick-billed murre (Uria lomvia ). The BMFs of these chemicals in thick-billed murre were lower than those of Dall's porpoise, suggesting the degradation and/or excretion of organochlorines through the uropygial gland with lipids. Moreover, the lowest BMF of Sigma CHL in thick-billed murre among organochlorines may indicate that chlordane compounds (CHLs) are metabolized more rapidly by this seabird than Dall's porpoise. |
