Biomarkers, PCBs, DDT, DDE, and plastic pollution in albatross of the north Pacific Ocean
The impacts of pollution in a remote area of the Pacific Ocean on seabirds were assessed. The amount and effects of accidentally ingested plastic on survival of Laysan albatross chicks were determined. Concentrations of synthetic organochlorine compounds and biomarkers of exposure to several classes of those compounds were measured in plasma of adults and chicks of both Laysan and Black-footed albatross of Sand Island, Midway Atoll. Concentrations of PCBs, DDT, DDE, and other chlorinated insecticides were measured in plasma and egg. Average, total PCB concentrations in the plasma of ten adult Laysan and five Black-footed albatross were 39 and 115 ng/g, respectively; DDE concentrations were 10.8 and 37.2 ng/mg respectively. Total pooled concentrations of PCBs in egg yolk of Laysan or Black-footed albatross were 1.06 or 3.84 {micro}g/g, respectively; DDE concentrations were 321.5 or 1,836.6 ng/g, respectively. Data will be presented on differences between chicks and adults, between species, and among sampling times throughout the nesting season. Serum retinol, T3 and T4 concentrations were quantified and correlated to concentrations of total PCBs, DDT, DDE, and other insecticides in the blood.
