Variation of antioxidant/detoxification enzyme activities in response to benzo[a]pyrene in the gazami crab Portunus trituberculatus

Responses of four toxicological indices (7-ethoxyresorufin-O-deethylase, EROD; glutathione S-transferase, GST; superoxide dismutase, SOD; and malondialdehyde, MDA) were studied in Portunus trituberculatus gill and liver during enrichment with benzo(a)pyrene (BaP) release at day 15. During BaP enrichment, toxicological indices in the gill and liver the 0.05 and 0.45 μg L-1 test groups were all significantly induced at day 1 (P 0.05). The gill of P. trituberculatus is more sensitive to BaP than the liver, but both organs could recover from our experimental BaP exposure
