| 摘 要： | 采用体内、体外染毒实验,研究了海洋中常见污染物0＃柴油、二甲苯以及重金属镉离子(Cd2+)对毛蚶(Scapharca subcrenata)肌肉超氧化物歧化酶(SOD)活性的影响.结果表明,在实验剂量范围内,3种污染物对毛蚶肌肉中SOD均表现出不同程度诱导作用;0＃柴油和二甲苯体内、体外染毒对毛蚶SOD活性影响规律基本一致,这两种污染物对毛蚶SOD活性变化的剂量-效应曲线均为抛物线型;Cd2+在体内、体外染毒对毛蚶肌肉SOD活性诱导曲线均不呈抛物线型,低浓度Cd2+对毛蚶SOD活性表现为显著诱导,随后曲线迅速下降,表明毛蚶对Cd2+污染反应十分敏感,也表明Cd2+对毛蚶毒性作用较强,3种毒物对毛蚶的毒性强弱次序为,Cd2+,0＃柴油、二甲苯.

| Abstract: | The effects of No. 0 diesel oil, dimethyl benzene, and Cd2+in sea on the activity of superoxide dismutase (SOD) of Scapharca subcrenata muscle were discussed by inside and outside body contamination. The results indicate that within the dose range inductions of the above three kinds of contaminants to SOD in Scapharca subcrenata are different. The effects of No. 0 diesel oil and dimethyl benzene on the activity of SOD of Scapharca subcrenata are basically identical and the dose - effect curves of the two contaminants on the activity of SOD show parabola, while the dose - effect curve of contamination with neither inside body nor outside body display parabola, and significant induction of low concentration of Cd2+ to SOD exists, and afterwards the curve shows a steep descent, which suggests that Scapharca subcrenata is sensitive to Cd2+ contamination, and toxicity of Cd2+ to Scapharca subcrenata is relatively obvious. The sequence of toxicity of the three kinds of contaminants is as follows: cadmium larger than No. 0 diesel oil larger than dimethyl benzene. |
