Understanding the impact of plastic and its additives on wild species is crucial as their presence in environment increases. Polybrominated diphenyl ethers (PBDEs), once used flame retardants, were restricted due to known toxic effects, but are still detected environment. Naturally occurring methoxylated PBDEs (MeO-BDEs) can result from PBDE transformation may cause similar hazardous effects. Yellow-legged gulls (Larus michahellis, YLG) Audouin's (Ichthyaetus audouinii, AG) highly susceptible additives, distribution, trophic position, behaviour. In this study, we assessed MeO-BDEs uptake different tissues effects physiological reproductive parameters. Findings indicate that, apart annual differences, adult AG accumulated more than YLG a natural breeding habitat (Deserta), while latter had lower levels city Porto. relation chicks, only Deserta showed higher concentrations chicks. Individual analysis each parameter revealed impacts for Deserta, with neurofunction immune system inhibition at MeO-BDE concentrations. For impaired neurofunction, chicks Porto exhibited potential genotoxicity triggered by levels. Overall health activation antioxidant defences compromised adults high values PBDEs, inflammation oxidative stress same species.
