摘　　要：通过研究久效磷(monocrotophos)对中国对虾(Penaeus chinensis)体内超氧化物歧化酶(SOD)活力的影响,从免疫毒理学方面初步探讨了有机磷农药对中国对虾的致毒作用.结果表明:久效磷胁迫可降低中国对虾体内SOD活力,且随药物浓度的增加和胁迫时间的延长,降低作用不断增强;几种组织的SOD活力对久效磷胁迫的敏感性,以肝胰腺最高,血淋巴的次之,肌肉组织相对较低.SOD活力的降低可使机体超氧阴离子自由基(O_2^-)增多,推测自由基损伤是久效磷对虾体产生毒性作用的另一可能途径。The paper reports the effect of monocrotophos on superoxide dismutase (SOD) activity in the tissues of P. chinensis. The toxicity mechanism of monocrotophos on the shrimp was performed and discussed with the method of immunotoxicology.The rsults indicate that monocrotophos stress could decrease the SOD activity in the haemolymph, hepatopancreas, and muscle of the shrimp. And it is found that the hepatic SOD activity is the most sensitive to monocrotophos stress. So monocrotohpos could poison the shrimp possibly by means of inducing free -adical damage.
