Tin and Tin-Resistant Microorganisms in Chesapeake Bay †

L. E. Hallas, J. J. Cooney
1981 Applied and Environmental Microbiology  
Sediment and water samples from nine stations in Chesapeake Bay were examined for tin content and for microbial populations resistant to inorganic tin (75 mg of Sn liter-' as SnCL4.5H20) or to the organotin compound dimethyltin chloride [15 mg of Sn liter-' as (CH3)2SnCl2]. Tin concentrations in sediments were higher (3.0 to 7.9 mg kg-') at sites impacted by human activity than at open water sites (0.8 to 0.9 mg kg-'), and they were very high (239.6 mg kg-') in Baltimore Harbor, which is
