Canada Proposes Five Chemical Substances For Toxic Designation; Calls for New Controls

摘要

Ottawa-Environment Canada and Health Canada have proposed designating five substances-the organotin compounds tributyltins and tetrabutyltins, plus benzenamine, dimethyl sulfate, and diethyl sulfate-as toxic under the Canadian Environmental Protection Act. The organotin proposals follow screening assessments conducted on 10 nonpesticidal organotin compounds, tin compounds used for a variety of uses, from catalysts to industrial biocides to preserving wood products.
