title: The classification of chemical carcinogens.
abstract: Various approaches to classification of chemical carcinogens developed by international and national agencies are described. Special features of each classification scheme with their strengths and weaknesses and their usefulness in regulation are discussed. Some recent examples of regulatory decisions on chemical hazards in Canada are presented, illustrating the many factors that need to be considered for risk assessment, in addition to merely categorizing carcinogens.
