Final assessments of the substances in Batch 9 of the “Challenge” program under the Chemicals Management Plan have been completed. Five of the substances have been proposed to be added to the List of Toxic Substances under the Canadian Environmental Protection Act, 1999, namely methyl eugenol, vanadium oxide, NDTHPM, TDGOPE, and Potassium bromate. Methyl eugenol may be used as a flavour ingredient. Vanadium oxide is used in the manufacture of high-strength steel. Potassium bromate is used in industrial applications, including as an oxidizing agent. NDTHPM is a dye and TGOPE is used in some epoxy resins and adhesive.
