中文摘要 | To explore both the acute joint toxicity of chlorophenols in aquatic biotas and the effective testing method, juvenile Carassius auratus (goldfish) were chosen and exposed to single compounds and binary mixtures of 2-Chlorophenol (MCP)and 2, 4-Dichlorophenol (DCP). The lethal concentrations and the antioxidant enzyme activities of superoxide dismustase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) were determined after 48-h exposure to MCP and DCP. The values of 49-h LC(50) were 30.72 mg/L (r(2) = 0.919) and 15.33 mg/L (r(2) = 0.954) in the acute lethal experiment,; exposed to single MCP and DCP, and 16.45 mg/L (r(2) = 0.977) and 8.21 mg/L (r(2) = 0.984) to binary equitoxic mixtures of MCP and DCP. The highest inductive activities of SOD and CAT, 207% +/- 81% and 325% +/- 164% of that of the control group, were found in the 1/4 LC(50) groups of MCP and the 1/2 LC(50) groups of MCP + DCP separately. The joint toxicity effect of MCP and DCP was partly an additive action in goldfish, which was assessed by the values of M (1.716) and M(0) (2) (M(0) > M > 1), according to the definition of toxic unit (TU). The significant induction of SOD and CAT suggested they might be used as potential biomarkers to indicate the oxidative stress mediated by single compounds and equitoxic binary mixtures of MCP and DCP in juvenile goldfish. |
