Regulation of discharge of organochlorines from pulp mills in Canada

Organochlorines are a group of chemicals including dioxins and furans, at least some of which are highly toxic to humans. Organochlorines are formed as a byproduct of the chlorine bleaching process in pulp mills, as well as in other ways. Current federal and provincial environmental protection legislation in Canada is too general to adequately deal with the problem of organochlorine discharge. In Sweden and Germany strict new guidelines have been set for the discharge of organochlorines; strict guidelines are also planned for Alberta. The author recommends that new regulations, dealing specifically with organochlorine discharge, be promulgated under the new Canadian Environmental Protection Act. The new regulations should apply equally to all pulp mills. Strict enforcement, through cooperation of federal and provincial authorities, is also advised.
