Abstract

Persistent organic pollutants were investigated in the blood of living seabirds (Pterodroma arminjoniana, Ony-choprion fuscatus, Sula dactylatra, Anous minutus, Anous stolidus and Sula leucogaster) from two Brazilian Con-servation Units -Trindade Island and Sa similar to o Pedro and Sa similar to o Paulo Archipelago. n-ary sumation PCBs (0.55 to 55.09 ng/g wet weight (ww), n-ary sumation DDTs (0.01 to 17.36 ng/g ww) and Mirex (0.01 to 5.53 ng/g ww) were predominant in all samples. Trindade petrel Pterodroma arminjoniana presented higher values than other seabirds, which is poten-tially related to diet and migratory behavior. Fluctuations in the trophic ecology data, through carbon and ni-trogen stable isotope ratios, warn of temporal variation in diet and foraging and highlight the importance of using a nondestructive matrix to allow long-term monitoring of POP contamination in seabirds from Brazilian Conservation Units. In addition, the data will fill the gaps in the POP baselines for seabirds from the tropical Atlantic Ocean. (AU)
