ABSTRACT
Increased activities of several detoxifying and antioxidant enzymes were detected in mollusc and fish from Spanish littoral areas with high metal contents. Ethanolic extracts from molluscs contained direct-acting and polar genotoxins of oxidative type, which were detected by strain TA102 of S. typhimurium and catalase-deficient strains of E. coli. Animals from contaminated sites contained less genotoxins than those from control areas. Polluted fishes displayed highly induced cytochrome P-450 activity and increased promutagen activation capabilities. In addition, specific forms of glutathione transferase and superoxide dismutase were induced, particularly highly acidic forms.
