The federal Toxic Substances Management Policy provides a framework based on two key objectives. The first or Track 1 objective is the virtual elimination from the environment of toxic substances that are persistent, bioaccumulative, and result primarily from human activity. This report presents an assessment of toxaphene against the criteria for selection of Track 1 substances under the Policy. It includes background information on toxaphene and documentation of the evidence considered in the assessment under the four criteria: whether the substance is predominantly anthropogenic; environmental persistence; bioaccumulation or bioconcentration factors; and toxicity under the priority substances provisions of the Canadian Environmental Protection Act.
