dc.description.abstract Polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticide levels were determined in blubber samples collected from stranded and incidentally by-caught Hector's (Cephalorhynchus hectori hectori) and Maui's (Cephalorhynchus hectori maui) dolphins from New Zealand waters between 1997 and 2009. PCBs (45 congeners) and a range of OC pesticides including dieldrin, hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT), along with its metabolites DDE and DDD were determined. OC pesticides dieldrin, p,p'-DDE, p,p'-DDD and p,p'-DDT were present at the highest concentrations. Sum DDT concentrations ranged from 93.7 to 8210 (Mean=1358, S.D=1974) and 252.4 to 57,390 (Mean=12,389, S.D=18,161)microg/kg wet weight in females and males, respectively. Similarly, Sigma45CB concentrations ranged from 45.5 to 981.3 (Mean=333.2, S.D=265.8) and 60.5 to 5574 (Mean=1833, S.D=1659)microg/kg wet weight in females and males, respectively. The transfer of SigmaDDTs and summed PCBs (both as SigmaICES7CBs and Sigma45CBs) between a pregnant female and her unborn fetus was calculated at 5.7% and 4.3%, respectively. As the fetus was close to term, this likely represents the degree of placental transfer. Concentrations of OC pesticides determined in the present study are higher than those previously reported for Hector's dolphins. Sum DDT and DDE/SigmaDDT levels calculated reveal New Zealand's legacy of DDT usage, particularly off the east coast of the South Island.
