The lack of information on the extent and industrial distribution of occupational exposure to carcinogens in most countries makes quantitative risk assessment and hazard surveillance very difficult. The CAREX (CARcinogen EXposure) database, constructed with support from the Europe Against Cancer program of the European Union, provides selected exposure data and documented estimates of the number of exposed orders by country, carcinogen, and industry. CAREX includes data on 139 carcinogens evaluated by the International Agency for Research on Cancer (all agents in Groups 1 and 2A, and selected agents in Group 2B), displayed across the 55 industrial classes of the United Nations systems (ISIC Revision 2). The 1990-93 occupational exposure to these carcinogens is estimated for the 15 countries of the European Union in 2 phases. First, estimates are generated automatically by the CAREX system on the basis of national work force data and exposure prevalence estimates from two reference countries (the United States and Finland) which had the most comprehensive data available on carcinogen exposures. Second, a network of national experts assesses these estimates in view of their similarity/dissimilarity to the perceived exposure patterns in their own countries. The CAREX system permits these experts to select appropriate first estimates or to generate and document modifications of these estimates in a personal computer-based system. If reasonably accurate workforce data and expert knowledge on national exposure patterns are available, the CAREX system may also be applied to additional countries. Computerized exposure information systems such as CAREX are a feasible way to collect, evaluate, save, and disseminate information on occupational exposures at the international level.
