高锰酸钾与敌百虫对草鱼幼鱼的联合毒性

The joint toxicity of potassium permanganate and trichlorphon to juvenile grass carps (nopharyngodon idellus) was investigated by the static test. Results showed that the combination of potassium permanganate and trichlorphon exhibited antagonistic effects at the exposure times of 24, 48, 72 and 96 h, while the antagonistic effects weakened gradually with the extension of time. The histopathological analysis indicated that the exposure to the mixture of potassium permanganate and trichlorphon caused various types of lesions in the livers, kidneys and gills of juvenile grass carps.
