石油污染对莫桑比克罗非鱼血清酶活性的影响

Effects of petroleum pollution on the activities of serum enzymes of Tilapia mossambica

本文通过分析莫桑比克罗非鱼血清酶活性的变化，研究石油对鱼类的致毒效应。试验结果表明，石油污染能升高血清谷草转氨酶、乳酸脱氢酶和碱性磷酸酶活性，石油对莫桑比克罗非鱼血清酶活性产生作用的浓度阈值为０．０５ｍｇ／ｄｍ３．分析鱼类血清酶活性的变化，可以为诊断石油污染提供科学依据。

The effect of petroleum pollution on the Tilapia mossambica was studied by analysing the changes of activities of serum glutamic-oxalacetic transaminase (GOT), alkaline phosphatase (ALP)and lactate dehydrogenase (LDH). The study results show that: (1) The activities of serum GOT, ALP and LDH increase in petroleum treated Tilapia mossambica. (2) The threshold of effect of petroleum on serum enzymes is 0. 05 mg/dm3. We think that it can diagnose the petroleum pollution by analysing the variances of activities of those enzymes.
