Chemicals, industrial processes and industries associated with cancer in humans.

The programme on the Evaluation of the Carcinogenic Risk of Chemicals to Humans has existed since 1971 and involves the preparation and publication of monographs that evaluate individual chemicals and, more recently, carcinogenic risks resulting from exposures to complex mixtures, since it is in this way that human populations are often exposed. Exposures occurring in the wood and leather industries and in the rubber manufacturing industry were thus the subject of recent IARC monographs. (A full Iist of IARC Monographs, both published and in press, is given in Appendix 1.) The evaluations contained in each volume of monographs are made by ¡ndependent international Working Groups and provide governments and their advisers with authoritative scientific opinions on which to base preventive measures.
