摘　　要：本研究采用半静态水质接触染毒方式，3．Omg／L的硝基苯对鲫鱼染毒，进行生物累积试验，气相色谱法测定鱼体内硝基苯含量。结果表明：鱼体不同器官对硝基苯的富集表现基本一致。其中，鱼鳃、肠对硝基苯摄取较迅速，累积量大，鲫鱼鳃中硝基苯最大浓度值达15．21mg／kg，硝基苯在肌肉中进行多次分配。肝、肾富集曲线呈现不同的变化特征，间接证明其中发生了硝基苯的代谢转化。用3．0mg／L的硝基苯处理，鲫鱼鳃对硝基苯的富集系数为2．35，肠2．30，肌；肉1．60，肝1．61，肾1．95，心脏1．34。根据计算平均累积量，鱼体~l-gg-官硝基苯累积量分布规律表现出肌肉〉鳃〉肠〉肾〉肝〉心脏的规律。Study used semi-static water contact with infected way,3.0mg/L of nitrobenzene on the fish exposed for bioaccumulation test, gas ehromatography fish nitrobenzene content.The results showed that： different organs of fish enrichment of nitrobenzene basically the same performance . Among them, the fish gill, intestine more rapid uptake of nitrobenzene , the cumulative volume,maximum concentration of nitrobenzene in fish gills value of 15.21mg/kg, nitrobenzene assigned multiple times in the muscles. Liver, kidney enrichment curves show different variations,which occurred indirect evidence of metabolic conversion of nitrobenzene.With 3.0mg/L nitrobenzene process,carp gill nitrobenzene enrichment factor of 2.35, 2.30 intestine,muscle 1.60, liver 1.61, kidneyl.95,heart 1.34.According to calculation of the average cumulative amount of nitrobenzene in fish organs showed accumulation distribution muscle〉gill〉intestine〉kidney〉liver〉heart of the law.
