摘要: Abstract The purpose of this study was to identify possible relationships between biochemical—Catalase, Superoxide dismutase (SOD) and Propionaldehyde dehydrogenase (PDH)—and histochemical—Neutral Red Retention time (NRR)—parameters mussels ( Mytilus galloprovincialis ) chemical (Hg, Pb, Cd, Zn, Cr, DDTs PCBs) contaminants from the most polluted area Venice Lagoon which lies around Porto Marghera (industrial pollution) city (domestic pollution). Sampling undertaken at beginning March 1995 repeated in 1996, just before spawning, when tissue concentrations pollutants reach their annual maxima. results organic contaminant analysis showed generally good agreement sites for two sampling periods, with values broadly 10% lower during 1996 as compared 1995. Metal tissues revealed greater variability than compounds. Distribution pattern biological parameters were more complex variable. apparent lack significant positive correlations antioxidant enzyme activities pollutant body burdens well low NRR are consistent present debate on use these indices markers contaminant-mediated stress molluscs.
