This chapter is a summary of investigations of the occurrence of tributyltin (TBT) and its less toxic degradation products in water and sediment in Canada in the period 1980–1985. Tributyltin was mainly found in areas of heavy boating or shipping traffic, which was consistent with its use as an antifouling agent. In 8% of the 269 locations across Canada at which samples were collected, TBT was found in water at concentrations that could cause chronic toxicity in a sensitive species, rainbow trout. Tributyltin was occasionally found in the surface microlayer of fresh water at much higher concentrations than in subsurface water. It was also found in 30% of sediment samples collected across Canada. The few fish analyzed that contained TBT were from harbors, a finding consistent with findings in water and sediment.
