研究了三种有机锡化合物--三甲基氯化锡、二甲基二氯化锡和二乙酸二丁基锡--和两种重金属--镉和六价铬--对法国卤虫死亡的影响。到目前为止，在这项研究中测试的所有化合物中，三甲基氯化锡是毒性最大的。五种化合物的毒性顺序为：三甲基氯化锡；重铬酸钾；二甲基二氯化锡；二乙酸二丁基锡；氯化镉。二烷基锡和三烷基锡在毒性上的巨大差异并不伴随着生物累积的同样大的差异。当水中锡浓度为10 mg/L时，二氯化二甲基锡的生物富集系数为50，三甲基氯化锡的生物富集系数为75。当水中锡浓度为100 mg/L时，二氯化二甲基锡和三甲基氯化锡的生物富集系数分别为6和9。三甲基氯化锡和镉以及三甲基氯化锡和铬的交互作用被发现是协同作用的。三甲基氯化锡与镉和铬一起使用的交互作用也被发现是协同作用的。(C)2001年学术出版社。
The effects of three organotin compounds-trimethyltin chloride, dimethyltin dichloride, and dibutyltin diacetate-and two heavy metals-cadmium and hexavalent chromium-on Artemia franciscana mortality are investigated in this study. Of all the compounds tested in this work, trimethyltin chloride was, by far, the most toxic. The toxicity order for the five compounds was trimethyltin chloride > potassium dichromate > dimethyltin dichloride > dibutyltin diacetate > cadmium chloride. The big difference in toxicity between dialkyltin and trialkyltin was not accompanied by an equally big difference in bioaccumulation. At a Sn concentration in water of 10 mg/L, the bioconcentration factor was 50 for dimethyltin dichloride and 75 for trimethyltin chloride. At a Sn concentration in water of 100 mg/L, the bioconcentration factor for 6 for dimethyltin dichloride and 9 for trimethyltin chloride. The interactive effect of trimethyltin chloride and cadmium, as well as that of trimethyltin chloride and chromium, was found to be synergistic. Also found to be synergistic was the interactive effect of trimethyltin chloride with cadmium and chromium applied together. (C) 2001 Academic Press.
