Tin and its compounds are among the most widely used chemicals in the history of mankind. Tin can form covalent bondings with carbon, and the generated products are consequently called organometallic or organotin compounds. The major applications or organotins are in the form of mono- and di-substituted compounds (so called non-pesticidal organotins), mainly utilized by the plastics industry. The knowledge of the environmental fate and effects of these compounds is at present limited. On request from The Swedish National Chemicals Inspectorate, the Swedish Environmental Research Group (MFG) has prepared a tentative environmental hazard assessment of mono- and dialkylated tin compounds, or more specifically some mono- and dimethyltin, mono- and dibutyltin, mono- and dioctyltin species.
