Nomination Summary for Organotins (N20030)
Nominated Substances: Di-n-butyltin dichloride, Dibutyltin, Dimethyltin, Dimethyltin dichloride, Methyltin, Monobutyltin, Monobutyltin trichloride, Trichloromethylstannane
Nomination Date: 05/08/2000
Nominator: NIEHS, EPA
Rationale: EPA has listed the organotins as drinking water contaminants with high priority for health research needs. There is a lack of toxicity and mechanistic data on the organotins occurring in drinking water although a related organotin (trimthyltin) is known to be neurotoxic. Organotins have wide application with more than 65% being used in PCV pipes. Organotins have been found in water samples collected from homes and commercial buildings supplied by PCV pipes.
