Effect of organotins on fecal pollution indicator organisms.

摘要: Pure cultures of Escherichia coli and Streptococcus faecalis environmental water samples were examined for the possibility that pollution involving organotin compounds could decrease values indicator organisms when standard methods applied to analysis samples. (CH3)2SnCl2 (CH3)3SnCl decreased viable counts at about 10 100 mg Sn liter-1 (8.4 X 10(-5) 8.4 10(-4) mol liter-1), tributyltin chloride was effective 0.1 1.0 10(-7) 10(-6) liter-1. These concentrations, particularly methyltin compounds, are greater than concentrations reported date these in aquatic ecosystems. Thus, alone would not be likely cause reductions measured by methods. However, it is suggested that, combined with other stressors or upon long exposure, organotins such as butyltins may contribute injury organisms.
