Organotin concentrations in the surface microlayer of British Columbia coastal waters in 1994 / J.A.J. Thompson ... [et al.]. : En13-5/96-167E-PDF
"Tributyltin is perhaps the most toxic chemical that has ever been deliberately introduced into the aquatic environment. It is an endocrine disruptor with reproductive efiects in some aquatic organisms at concentrations less than 1 ng Sn/L. It is also immunotoxic (thymus effects) to aquatic organisms and mammals and exerts effects on the thyroid gland in mammals. Through its use as an antifouling agent tributyltin has been responsible for population-level effects on whelks, dogwhelks, periwinkles, clams and oysters in Europe and elsewhere. Because of the extremely high toxicity of tributyltin, many countries in the 1980s and 1990s regulated its antifouling uses. This article reports the results of a small survey of the marine surface microlayer in 15 locations in southwestern British Columbia for the occurrence of tributyltin and other organotin species, This study complements a study of neogastropod imposex frequency in those same locations, and a survey of organotin compounds in water and sediment across Canada, both of which were undertaken to determine the effectiveness of the 1989 Canadian regulation of antifouling uses of tributyltin"--Management perspective.
