Contaminants in the Sediments and Biota of the Western Beaufort Sea. National211 Status and Trends Program for Marine Environmental Quality

摘要

Beaufort Sea surficial sediments and benthic biota samples were analyzed for a211u001esuite of: trace metals; organochlorine contaminants, including pesticides and 211u001epolychlorinated biphenyls (PCBs); polyaromatic hydrocarbons (PAHs); and 211u001eradionuclides. The samples were collected in 1993 at 11 sites during a cruise of 211u001ethe Coast Guard icebreaker 'Polar Star.' Trace metals were only analyzed in the 211u001esediments. In the samples, only arsenic displayed high concentrations (up to 58 211u001eppm grainsize-corrected value) that may be related to the presence of ore 211u001edeposits in the area.
