Lead and cadmium levels in Galapagos Penguin Spheniscus Mendiculus, flightless cormorant phalacrocorax harrisi, and waved albatross phoebastria irrorata.

Heavy metals are a threat to wildlife, and they have yet to be analyzed in seabirds from the Galápagos Archipelago. To gauge their prevalence inGalápagos seabird species, we collected and analyzed feather samples from Galapagos Penguins Spheniscus mendiculus, Flightless CormorantsPhalacrocorax harrisi, and Waved Albatross Phoebastria irrorata in seven different breeding areas in 2011 and 2012 as part of an ongoingmark-recapture study. The results showed that lead is higher in penguins and cormorants; cadmium was found to be below the limit forquantification in all our samples. The heavy metals recorded did not have a clear local source related to human activities, as breeding areas arenot located near populated areas. Environmental media (soil, water), marine currents, and atmospheric deposition are possible sources.
