Abstract These substances are considered "toxic" as defined under the Canadian Environmental Protection Act. This report reviews the available environmental and toxicological data on polychlorinated dibenzodioxins (dioxins) and polychlorinated dibenzofurans (furans). Exposures to these substances in the workplace, or from industrial accidents, have resulted in changes in the skin (including chloracne) that can persist for many years. Extensive exposures have also produced neurological and psychological effects (including sexual dysfunction), elevated blood levels of some enzymes and averse effects on the foetus. The evidence of a link between cancer incidence or mortality and exposure to dioxins and furans is equivocal.
