Persistent organic pollutant patterns in seabirds from marine protected areas in the tropical Atlantic Ocean

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.
