Monitoring organic contaminants in eggs of glaucous and glaucous-winged gulls (Larus hyperboreus and Larus glaucescens) from Alaska.

摘要: Abstract Gull eggs have been used to monitor contaminants in many parts of the world. The Seabird Tissue Archival and Monitoring Project (STAMP) is a long-term program designed track trends pollutants northern marine environments using seabird eggs. Glaucous glaucous-winged gull ( Larus hyperboreus glaucescens ) collected 2005 from seven Alaskan colonies were analyzed for organic contaminants. Concentrations ranged below detection limits 322 ng g −1 wet mass one egg 4,4′-DDE differed among samples Gulf Alaska Bering Chukchi Seas. Chick growth survival rates may be affected by contaminant levels found eggs, but should safe human consumption if they are eaten small quantities. STAMP plans continue collecting banking future real-time retrospective analyses.
