摘要
采用概率分析法对乐果果进行急性毒性生物测定。24、48、72和96 h LC50分别为11.63、10.08、10.54和9.136 ppm。在本研究中，乐果对96小时LC50条件下的鼠鳃的影响表现为二级鳃片上皮的变性、空泡化、融合、二级鳃片缩短、初级和次级鳃片的厚度和融合
STUDIES ON TOXICITY EVALUATION OF DIMETHOATE ON THE FRESHWATER FISH RASBORA DANICONUS WITH SPECIAL REFERENCE TO THE GILL HISTOPATHOLOGY
: The acute toxicity bioassay of dimethoate was carried out by the probit analysis method. The 24, 48, 72 and 96 h LC50 values were obtained as 11.63, 10.08, 10.54 and 9.136 ppm respectively. In the present investigation the effect of dimethoate on the gill of Rasbora daniconius at 96 hours LC50 marked histopathological changes found like degeneration of epithelium of secondary gill lamellae, vacuolation, fusion, shortening of secondary gill lamellae, thickness and fusion of primary and secondary gill lamellae
