Abstract [en]

As industrial chemicals, organotin compounds are predominantly applied as polyvinyl chloride (PVC) stabilizer, and biocides. They are widely encountered in environmental samples and may be introduced into landfills by disposal of municipal solid waste or sewage sludge. In the present study, leachate samples were obtained from several sanitary landfill sites in Sweden, Italy, and Germany. These samples were analyzed by means of a highly sensitive and species-selective method for methyltin, butyltin, and octyltin species. In total, twelve samples from eight different landfill sites at various ages were investigated. The findings of all target compounds range between less than the limit of detection at 0.1 mug/L and, at maximum, 4 mug/L. Only octyltin compounds can be attributed to PVC products with any certainty, whereas for methyltin and butyltin compounds alternative and less distinct sources exist. Organotin compounds are subject to microbial transformation, such as dealkylation and methylation processes. Consequently, caution should be exercised when attributing findings to potential sources and deriving any predicted environmental concentrations.
