Effect of organotins on fecal pollution indicator organisms
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. (CH/sub 3/)2SnC/sub 2/ and (CH/sub 3/)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.
