Abstract

Abstract: European eels ( Anguilla anguilla ) are an endangered species throughout their range, and chlorine organic compounds are some of the most important pollutants for marine species. Data on contaminants in eel stocks remain incomplete, so organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in muscle of European eels from four Spanish Mediterranean ecosystems were analyzed. COPs are presents in eels from all areas, but some compounds are not detected: HCH α, β and γ (lindane), endosulfan sulfate, heptachlor, and PCBs 28, 52 and 180. The high percentage of DDT 2, 4′ in eels from S'Albufera des Grau Natural Park, an ecosystem with good ecological status according to the Water Framework Directive, and the presence of PCBs in S'Albufereta Natural Reserve indicate the need to carry out further studies in the future. The results obtained can improve the management of this species in the studied areas. Graphical abstract: Unlabelled Image Highlights: COPs are present in European eels from four Spanish Mediterranean ecosystems. Data about COPs are necessary to improve the management of eels. High percentage of DDT 2, 4′ is present in an ecosystem with good ecological status. PCBs were only present in eels from S'Albufereta Natural Reserve.
