Evaluation of per- and polyfluoroalkyl substances and organochlorine pesticides in great tit eggs from areas with different anthropogenic pressures in Padova, Italy.

ABSTRACT: This study investigates the contamination of per- and polyfluoroalkyl substances (PFAS) and organochlorine pesticides (OCPs) in eggs of great tits (Parus major) from urban, agricultural, and woodland areas from Italy. PFOS was the most prevalent PFAS, followed by long-chain perfluorocarboxylic acids (PFCAs). Agricultural areas showed the highest PFOS concentrations, while woodland areas exhibited higher concentrations of PFUnDA and PFTrDA. The observed PFCA chain length patterns across different locations highlight the influence of atmospheric chemistry, especially the oxidative breakdown of PFCA precursors, in determining contamination profiles. OCP contamination was dominated by DDT metabolites, especially p,p'-DDE, with higher concentrations in urban areas, reflecting historical pestici
