Gull Sets Arctic Pollution Record for Birds
A small Arctic gull has set a record as the bird most contaminated by two banned industrial pollutants, scientists said on Thursday. Eggs of the ivory gull, which has a population of about 14,000 from Siberia to Canada, were found to have the highest known concentrations of PCBs, long used in products such as paints or plastics, and the pesticide DDT. "Environmental poisons are threatening ivory gulls," the Norwegian Polar Institute said in a statement of eggs collected off northern Norway and Russia. "Levels of PCB and DDT are higher in ivory gulls than in other Arctic seabirds."
