在四组柴油分散液质量浓度下(0、5、20、50 mg/L),马粪海胆(Hemicentrotus Pulcherrimus)的肠、生殖腺、体液三个部位的抗氧化还原系统谷胱甘肽过氧化物酶GPx活力的变化情况实验结果表明,随着污染暴露时间的增加,三个部位的GPx活性均呈现出先被诱导,后被抑制的规律,并且油浓度越高,出现诱导和抑制效应的时间越早,活性变化的幅度越大。由此可见GPx活力的变化在一定程度上能够反映油污染强度及其对海洋生物的毒理效应,可作为海洋石油烃污染监测的毒理学指标。
In the four groups of diesel oil dispersions (0, 5, 20, and 50 mg / L), the antioxidant and reducing system glutathione peroxides (GSHs) in three parts of gut, gonad and body fluid of Hemicentrotus Pulcherrimus The results showed that the GPx activity of all the three parts showed the first to be induced and then suppressed, and the higher the oil concentration, the longer the time of inducing and inhibiting effect Early, the greater the extent of activity changes. It can be seen that the change of GPx activity can reflect the intensity of oil pollution and its toxicological effects on marine organisms to a certain extent and can be used as a toxicological indicator for the monitoring of marine petroleum hydrocarbon pollution.
