【 摘 要 】

At present, significant adverse hydrocarbon influence on the Pribilof Island rock sandpiper (Calidris ptilocnemis ptilocnemis) is unlikely. Almost the entire population overwinters in Cook Inlet and breeds on four Bering Sea islands. Passive samplers deployed several times in a three year period and corresponding sediment and soft tissue samples on St. Paul Island and in Cook Inlet generally accumulated small quantities of polycyclic aromatic hydrocarbons (PAHs). Composition was consistent with oil in <15% of the passive samplers and rarely in soft tissue. Total PAH concentrations in corresponding sediment were very low (<42 ng/g dry weight); composition was consistent with oil in 39% of these samples and biomarker composition confirmed this on St Paul Island. However, composition was dominated by normal alkanes from natural sources. (C) 2016 The Authors. Published by Elsevier Ltd.
