Methyltins in the marine environment

Methyltins were occasionally observed in some natural waters. The nature of a marine sediment determines its organotin burdens. Mono- and dimethyltin compounds were found in polluted marine sediments whereas non-polluted, oxiccoastal sediments contained primarily trimethyltin. The net methylation rate is evidently independent of the inorganic tin content of a sediment. Methyltin in fish is about 3–6% of the total tin content while limpets contain significant amounts of organotin compounds, ranging between 35 and 75% of the total tin. No trimethyltin was detected in green macro-algae and seawater, although limpets, fish and sediments have measurable levels.
