title: Simultaneous speciation of butyltin and phenyltin compounds in the waters of south-west Spain.
abstract: An analytical method for the simultaneous speciation of butylin and phenyltin compounds has been applied to a study of the water quality in six locations (rivers and sea) in South West Spain. It was not intended to provide a comprehensive survey of the area but to establish what the maximum levels might be for a subsequent and more detailed study. Phenyltin species were not found in any sample, however tributyltin was present (100-400 ng l-1) in the Cadiz Bay samples, which suggests that the biological water quality may sometimes be depressed. Wherever tributyltin was present, dibutyltin and monobutyltin occurred, possibly, as a result of a degradation process.
