East Versus West: Organic Contaminant Differences In Brown Pelican (Pelecanus Occidentalis) Eggs From South Carolina, Usa And The Gulf Of California, Mexico, Stacy S. Vander Pol, Daniel W. Anderson, Patrick G.R. Jodice, Joyce E. Stuckey

United States Geological Survey: Staff Publications

Brown pelicans (Pelecanus occidentalis) were listed as endangered in the United States in 1970, largely due to reproductive failure and mortality caused by organochlorine contaminants, such as DDT. The southeast population, P.o. carolinensis, was delisted in 1985, while the west coast population, P.o. californicus, was not delisted until 2009. As fish-eating coastal seabirds, brown pelicans may serve as a biomonitors. Organic contaminants were examined in brown pelican eggs collected from the Gulf of California in 2004 and South Carolina in 2005 using gas chromatography/mass spectrometry (GC/MS). Contaminants were compared using all individual data as well as …
