“…One possible route as discussed by Brinckman ( 4) is the dealkylation of the trialkyltin species eventually to Sn(IV), and the microbial methylation of Sn(IV) to the various methyltin species. Increasing methyltin concentrations with increasing anthropogenic tin influxes has been noted in the Chesapeake Bay (4).…”

“…The highest concentrations reported in environmental water samples are in the order of 0.35 ,ug of Sn liter-' (2.9 x 10-9 mol of Sn liter-) in unfiltered subsurface fresh water and 0.025 mg of Sn liter-' (2.1 x 10-7 mol of Sn liter-') in unfiltered fresh water which included the surface microlayer. Monobutyltins have been reported in estuarine waters(3,6,23), and they are presumably derived from tributyltins leached from antifouling paints on boat hulls. Thus, it is likely that tributyltins will be found in estuarine systems as APPL.…”

Pure cultures of Escherichia coli and Streptococcusfaecalis 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-' (8.4 x 10-5 to 8.4 x 10-4 mol of Sn liter-'), and tributyltin chloride was effective at about 0.1 to 1.0 mg of Sn liter-' (8.4 x 10-7 to 8.4 x 10-6 mol of Sn liter-'. 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. * Corresponding author. waters and sediments in areas impacted by human activity (32, 40). MATERIALS AND METHODS Microorganisms and culture preparation. Pure cultures of Streptococcusfaecalis ATCC 19433 and of an environmental isolate of E. coli coded UMB-1 were maintained on Trypticase soy agar slants. The E. coli was isolated from water obtained from Boston Harbor, Boston, Mass. It was identified as an E. coli based on indole-methyl red-Voges-Proskauer-citrate reactions and the production of acid and gas from lactose at 44.5°C. Cultures for experiments were grown in Trypticase soy broth (BBL Microbiology Systems, Cockeysville, Md.) at 20 to 22°C for 24 h. A 1% (vol/vol) inoculum was then transferred to fresh Trypticase soy broth and incubated for 18 h.
