摘要
为了解2种农药联合染毒对鲫鱼肌肉、肾脏和肝胰脏CAT活性的影响,将鲫鱼(Carassius au-ratus)分别暴露于不同浓度的阿特拉津与氯氰菊酯的混合溶液中进行了试验。结果表明:低浓度阿特拉津(5.3mg/L)与氯氰菊酯联合染毒对鲫鱼肝胰脏CAT活性的诱导作用随染毒时间的增加而增加,染毒第5-8天对鲫鱼肾脏CAT活性有抑制作用;高浓度阿特拉津(10.6mg/L)与氯氰菊酯联合染毒第8-15天对鲫鱼肾脏CAT活性有诱导作用;阿特拉津与氯氰菊酯联合染毒对鲫鱼肌肉CAT活性表现为先诱导、后抑制。表明,鲫鱼组织CAT活性变化与阿特拉津和氯氰菊酯联合染毒存在剂量-效应和时间-效应关系。
The results from studying the effect of Atrazine and Cypermethrin combination with different concentration on CAT activity of muscle,kidney and liver of Carassius auratus showed that the hepatopancreans CAT activity of Carassius auratus treated with 5.3mg/L Atrazine and 1.1g/L Cypermethrin increased with the increase of treatment time,the kidney CAT activity of Carassius auratus treated with 5.3mg/L Atrazine and 1.1g/L Cypermethrin was inhibited 5~8 days later,the hepatopancreans CAT activity of Carassius auratus treated with 10.6mg/L Atrazine and 1.1μg/L Cypermethrin increased 8~15 days later,and Atrazine and Cypermethrin contamination first increased and then inhibited the muscle CAT activity of Carassius auratus.There are the relationships between Atrazine and Cypermethrin concentration and the CAT activity and between Atrazine and Cypermethrin contamination time and the CAT activity.
