Abstract

Abstract: Persistent organic pollutants were investigated in the blood of living seabirds ( Pterodroma arminjoniana, Onychoprion fuscatus, Sula dactylatra, Anous minutus, Anous stolidus and Sula leucogaster ) from two Brazilian Conservation Units - Trindade Island and São Pedro and São Paulo Archipelago. ∑PCBs (0.55 to 55.09 ng/g wet weight (ww), ∑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 potentially related to diet and migratory behavior. Fluctuations in the trophic ecology data, through carbon and nitrogen 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. Graphical abstract: Unlabelled Image Highlights: First report of POP concentrations in live seabirds of Brazilian marine protected areas. Wintering areas may contribute to high POP concentrations in Trindade petrels. POPs in petrels were one or two orders of magnitude higher than those in other species PCBs, DDTs and Mirex were the predominant POPs found in the blood of seabirds. Foraging areas and food resource availability can influence contamination profiles.
