Objectives-To construct a computer assisted information system for the estimation of the numbers of workers exposed to established and suspected human carcinogens in the member states of the European Union (EU). Methods-A database called CAREX (carcinogen exposure) was designed to provide selected exposure data and documented estimates of the number of workers exposed to carcinogens by country, carcinogen, and industry. CAREX includes data on agents evaluated by the International Agency for Research on Cancer (IARC) (all agents in groups 1 and 2A as of February 1995, and selected agents in group 2B) and on ionising radiation, displayed across the 55 industrial classes. The 1990-3 occupational exposure was estimated in two phases. Firstly, estimates were generated by the CAREX system on the basis of national labour force data and exposure prevalence estimates from two reference countries (Finland and the United States) which had the most comprehensive data available on exposures to these agents. For selected countries, these estimates were then refined by national experts in view of the perceived exposure patterns in their own countries compared with those of the reference countries. Results-About 32 million workers (23% of those employed) in the EU were exposed to agents covered by CAREX. At least 22 million workers were exposed to IARC group 1 carcinogens. The exposed workers had altogether 42 million exposures (1.3 mean exposures for each exposed worker). The most common exposures were solar radiation (9.1 million workers exposed at least 75% of working time), environmental tobacco smoke (7.5 million workers exposed at least 75% of working time), crystalline silica (3.2 million exposed), diesel exhaust (3.0 million), radon (2.7 million), and wood dust (2.6 million). Conclusion-These preliminary estimates indicate that in the early 1990s, a substantial proportion of workers in the EU were exposed to carcinogens.
Previous job‐exposure matrices (JEM) have usually cross‐tabulated classified exposure information by chemical agent and occupational class. A new Finnish job‐exposure matrix (FINJEM) was constructed for exposure assessment in large register‐based studies. Unlike most other JEMs, FINJEM was designed to contain definitions, inferences, exposure data, and references. This documentation enables FINJEM to be applied also as a general exposure information system for hazard control, risk quantification and hazard surveillance. The system includes, e.g., workforce data, and it provides information on the numbers of exposed workers in Finland by agent, occupation, and level of exposure. The exposures of FINJEM cover major physical, chemical, microbiological, ergonomic, and psychosocial factors. The assessment period is 1945–1997, divided into several subperiods. Exposure is described by the prevalence of exposure and the level of exposure among the exposed, both estimated mainly on continuous scales. The user may also define the final criteria of exposure, and thereby influence the magnitude of misclassification. Am. J. Ind. Med. 33:409–417, 1998. © 1998 Wiley‐Liss, Inc.
Data on occupational contact urticaria (protein contact dermatitis included) in Finland during 1990-1994 were analyzed. Altogether 815 cases were reported to the Finnish Register of Occupational Diseases during this period, compared with 1944 cases of occupational allergic contact dermatitis. Accordingly, the total number of occupational allergic contact dermatoses was 2759, 29.5% being contact urticaria and 70.5% being allergic contact dermatitis. Occupational contact urticaria was much more common in women (70%) than in men (30%). The 6 most common causes of contact urticaria were (1) cow dander (362 cases = 44.4%), (2) natural rubber latex (193 cases = 23.7%), (3) flour, grains and feed (92 cases = 11.3%), (4) handling of foodstuffs (25 cases = 3.1%), (5) industrial enzymes (14 cases = 1.7%) and (6) decorative plants (13 cases = 1.6%). The occupations with the highest numbers of occupational contact urticaria were farmers (341 cases), domestic animal attendants (61), bakers (53), nurses (42), chefs (40) and dental assistants (28). The ranking list of the most common occupations with occupational contact urticaria per 100,000 employed workers was as follows: (1) bakers (140.5 cases per 100,000 employed persons), (2) preparers of processed food, (3) dental assistants, (4) veterinary surgeons, (5) domestic animal attendants, (6) farmers and silviculturalists, (7) chefs, cooks and cold buffet managers, (8) dairy workers, (9) horticultural supervisors, (10) laboratory technicians and radiographers, (11) physicians, (12) butchers and sausage makers, (13) laboratory assistants, (14) dentists and (15) nurses (21.2 cases per 100,000 employed person). Low-molecular-weight chemicals caused very few cases of occupational contact urticaria, the most common being 2-ethylhexyl acrylate (5 cases). To summarize, occupational contact urticaria forms a large group of occupational contact dermatoses, and dermatologists need to be able to diagnose IgE-mediated immediate skin allergic diseases.
Furriers, bakers, and livestock breeders had the most elevated relative risk of occupational rhinitis. Occupational rhinitis cases reported at a younger age than asthma, suggesting that rhinitis often precedes asthma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
