PCB’s and Organochlorine Pesticides in Eel and Flounder in the Tagus Estuary

Within the Tagus estuary, in the vicinity of an industrial zone (chloroalkaly, pesticides, fertilizers and steelworks plants) a monitoring programme on Organochlorine Pesticides and Polychlorinated Biphenyls has been carried out since 1983.This zone is influenced by agriculture activities as well. Flounder (Platichthys flesus) and eel (Anguilla anguilla) have been sampled twice a year. Analysis have been carried out both on liver and fillet. Low concentrations were observed which present neither risk for survival and normal development of living species nor to public health.
