Assessing perfluoroalkyl substance pollution in Central Mediterranean breeding shearwaters.

ABSTRACT: Per- and polyfluoroalkyl substances (PFAS) are synthetic organofluorine compounds used in various products, which are highly durable in the environment and may pose risks to wildlife health. We investigated the blood cell concentrations of PFAS in breeding Scopoli's shearwaters (Calonectris diomedea) from three different colonies in the central and southern Mediterranean (Linosa, Malta, and La Maddalena). Shearwaters are flexible, high trophic level foragers, and foraging areas may differ according to sex and breeding stage. We examined inter- and intracolony differences in PFAS blood concentrations and compared them with exploited foraging areas and dietary tracers. Per- and polyfluoroalkyl substances were detected in all samples, with the major congeners detected in descending order bein
