Pure cultures of Escherichia coli and Streptococcus faecalis and environmental water samples were examined for the possibility that pollution involving organotin compounds could decrease the values for indicator organisms when standard methods were applied to the analysis of water samples. (CH3)2SnCl2 and (CH3)3SnCl decreased viable counts at about 10 to 100 mg of Sn liter-1 (8.4 X 10(-5) to 8.4 X 10(-4) mol of Sn liter-1), and tributyltin chloride was effective at about 0.1 to 1.0 mg of Sn liter-1 (8.4 X 10(-7) to 8.4 X 10(-6) mol of Sn liter-1. These concentrations, particularly for the methyltin compounds, are greater than the concentrations reported to date for these compounds in aquatic ecosystems. Thus, organotin compounds alone would not be likely to cause reductions in counts of indicator organisms measured by standard methods. However, it is suggested that, when combined with other environmental stressors or upon long exposure, organotins such as butyltins may contribute to the injury of indicator organisms.
对大肠杆菌和粪链球菌的纯培养物以及环境水样进行了检测，以研究在对水样分析应用标准方法时，涉及有机锡化合物的污染是否会降低指示生物的值。二甲基氯化锡[(CH3)2SnCl2]和三甲基氯化锡[(CH3)3SnCl]在锡含量约为10至100毫克/升（8.4×10(-5)至8.4×10(-4)摩尔/升）时可降低活菌数，而三丁基氯化锡在锡含量约为0.1至1.0毫克/升（8.4×10(-7)至8.4×10(-6)摩尔/升）时有效。这些浓度，特别是甲基锡化合物的浓度，高于迄今为止在水生生态系统中报道的这些化合物的浓度。因此，仅有机锡化合物不太可能导致通过标准方法测得的指示生物数量减少。然而，有人提出，当与其他环境压力源结合或长期接触时，诸如丁基锡之类的有机锡可能会对指示生物造成损害。
