| 摘 要： | 罗非鱼能较快的吸收水体中的DDT并在6h达到积累高峰，DDT在各器官的分布是不均匀的，按24h放射性活度的高低排列是：肝胰脏、胆囊、肠、脑、鳃和肌肉．肝胰脏在24h的浓集系数为48477，是肌肉的57倍．纯中药鱼病保护剂──FDP能促进罗非鱼对DDT的吸收和降解．罗非鱼经FDP浸泡后，在暴露于14C－DDT6h内，能普遍的提高各器官对DDT的吸收能力．肝胰脏积累DDT的能力加强，达对照组的1．69倍．24h经FDP处理的罗非鱼肝胰脏的总放射性活度明显下降，极性降解产物比例增加．说明FDP对罗非鱼的肝胰脏的解毒功能有促进作用．

| Abstract: | The present study investigated the effect of FDP, a medicine for fish diseases protection, on the uptake and metabolism of DDT in Tilapia. Results showed that the fish could rapidly uptake 14C-DDT from ambient water and degradated DDT into its metabo-lites, mainly DDD. FDP could enhance uptake of DDT of the fish and also stimulate the metabolism and elimination hence improving the physiological function of the fish. |
