Persistent Organic Pollutants (POPs), Current Use Pesticides (CUPs) and Polycyclic Aromatic Hydrocarbons (PAHs) in edible marine invertebrates from a Patagonian harbor

Despite their global ban in 2001, persistent organic pollutants (POPs) remain detectable in marine species, posing ongoing environmental and health risks. Current use pesticides (CUPs) like chlorpyrifos and chlorothalonil, along with polycyclic aromatic hydrocarbons (PAHs), also contaminate coastal areas, affecting human health. This study assessed POPs, CUPs and PAHs in bivalves, gastropods, polychaetes, crustaceans, and echinoderms from an Atlantic Patagonian harbor. Concentrations of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) ranged from Collapse
