摘要：

This paper reports on contamination levels and their sub-lethal toxicological effects in specimens of the European eel (Anguilla anguilla) in the Orbetello Lagoon, (Tuscany, Italy). Organochlorine pesticides (OC) and polychlorinated biphenyls (PCBs) were investigated as priority pollutants in muscle tissue. Phase I P450 enzymes, i.e., EROD, B(a)PMO and the two reductases (NADH ferryred and cyt c.), and cholinesterase (ChE) were assayed in liver and muscle as sensitive biological indicators of fish health. PCBs, lindane and p,p'DDE in muscles showed a wide concentration range (0.001-0.025 mu g g(-1) wet weight) and attained the lowest levels in the eastern basin. High homogeneity and relatively low values were observed for phase I P450 enzymes, suggesting that no significant detoxification process of OC pesticides and PCBs occurred. The threat posed by organophosphate insecticides (OP) and CB compounds was also evidenced by ChE activity. The integrated response of phase I P450 enzymes and ChE activity being an indicator of potential effects of toxic contaminant levels on reproductive success and population decline of eels, can be used to assess the overall lagoon quality.
