[Prevention of occupational carcinogens: perspectives opened by the evaluation of risks and preventive actions].
The first part of the review deals with the present situation in terms of prevention against potential carcinogenic substances in France. A significant effort should be devoted to the measurement of contaminants--not only carcinogenic substances--in the workplace. This is a prerequisite for setting a data base in terms of potential occupational risk. Moreover gaps exist also as far as the definition of the technical means aimed at the reduction of risk is concerned. These conclusions put into light the importance of the contribution that "industrial hygienists" would bring in France. In the second part of the review, the methodological content of the risk assessment and risk management procedures is described and illustrated. Risk assessment of carcinogens deals: with the identification of potential carcinogens through epidemiology, animal bio-assays and short term tests; with the quantitative estimation of the magnitude of the potential carcinogenic risk among the exposed workers. It appears necessary to carry out systematic surveys of the number of workers exposed to the carcinogenic substances. The risk assessment procedure is applied to 5 substances BCME, MOCA, Acrylonitrile, Chromium, Nickel and some compounds of these metals. The number of potential excess cancers related to a unit lifelong exposure to Nickel compounds is estimated. This requires exposure-response models which are critically analysed. Risk management is devoted to the choice of primary health care policies. The methodology of risk management consists of: identifying various control policies; quantitative estimation of their efficiency--indicators of the efficiency are discussed--and of their cost; choice among these policies with the help of a cost-effectiveness analysis when necessary. The procedure is illustrated in the case of Acrylonitrile control in a facility.
