| 摘 要： | 研究了三甲基氯化锡(TMT)对蛋白核小球藻、大型溞和斑马鱼的急性毒性影响.结果表明,TMT在实验浓度下,对蛋白核小球藻的生长有抑制作用,浓度越高抑制作用越明显.较高浓度组(5.31,20mg/L)可致死部分蛋白核小球藻细胞,TMT对蛋白核小球藻的96h-EC50为0.46mg/L,属于极高毒物质;TMT对大型溞的48h-LC50为0.087mg/L,也属于极高毒性;TMT对斑马鱼的96h-LC50为2.45mg/L,属于高毒性.TMT对这3种水生生物的抑制率/致死率(EC50/LC50)随时间呈规律性变化.TMT的神经毒性和亲脂特性可能是其对水生生物较高毒性的主要原因. |

| Abstract: | A study was carried out on the acute toxicity effects of Trimethyltin chloride(TMT) on Chlorela pyrenoidosa,Daphnia magna and Danio rerio.The results suggested that the growth of Chlorela pyrenoidosa was inhibited in the TMT of experimental content,the inhibiting effect increased significantly with the concentration increasing.The part of Chlorela pyrenoidosa cells even would be lethal in the higher concentration group(5.31,20mg/L).The toxic effects of TMT had the highest toxicity to Chlorela pyrenoidosa an... |
