消油剂处理120#燃料油对海水青鳉（Oryzias melastigma）胚胎抗氧化酶活性影响的研究
Effects of dispersant and #120 fuel oil exposure on antioxidant enzyme activity ofOryzias melastigma embryos
摘要
Abstract
In this paper, we consider the acute toxicities of #120 fuel oil water-accommodated fractions (WAFs) and biologically enhanced water-accommodated fractions (BE-WAFs) onOryzias melastigma embryos. Specifically, in our study, we investigated the effects of WAFs and CE-WAFs with different concentrations on the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione S-transferase (GST). The results show that the activities of SOD, CAT, and GST vary significantly after experiencing oxidative stress from petroleum hydrocarbons. With increasing the TPH concentration and duration of exposure, the activities of SOD, CAT, and GST showed various degrees of inductive and inhibitory effects. Of the three enzymes, the activity of SOD varied most significantly when exposed to petroleum hydrocarbons. GST also showed sensitivity when exposed to a dispersant alone. These study results indicate that the SOD inO. melastigma has the highest sensitivity to pollution from petroleum hydrocarbons and is suitable for use as a biomarker for monitoring marine oil pollution.关键词
