Perfluorinated Carboxylates and Sulfonates in Seabird eggs from the Pacific Coast of Canada: spatial and temporal trends
There is a continuing need to monitor contamination of the marine environment by xenobiotic compounds, particularly those which are persistent and accumulate in food chains. Eggs of marine birds have proven to be an efficient and effective means of measuring and tracking substances, such as persiste...

There is a continuing need to monitor contamination of the marine environment by xenobiotic compounds, particularly those which are persistent and accumulate in food chains. Eggs of marine birds have proven to be an efficient and effective means of measuring and tracking substances, such as persistent organic pollutants (POPs) and mercury which are transferred from the female bird to the egg via yolk lipids or proteins. Here we report and discuss data from long term monitoring of POPs and mercury in seabird eggs from the northeast Pacific. For this program, the marine system was divided, and representative species selected. The nearshore subsurface is monitored using two cormorant, Phalacrocorax, species, auritus and pelagicus, both feed on a variety of benthic and pelagic fish. The offshore subsurface is monitored using the rhinoceros auklet, Cerorhinca monocerata, a feeder mainly on small pelagic fishes, with the offshore surface species, the Leach’s storm-petrel, Oceanodroma leucorhoa, which feeds mainly on surface plankton and larval fishes.
