TICAREX: Exposiciones laborales a agentes cancerígenos y plaguicidas en Costa Rica
2005
The European data system CAREX takes the workforce of a country grouped into 55 economic sectors according to the
International Economic Activity Classification (IEAC) of the United Nations, the second 1968 revision and through the
application of proportions of workers exposed to 139 carcinogenic agents based on data from industrial hygiene studies,
converting it into the total workforce exposed to carcinogens by sector. . In this article we describe a modification and
extension of of the CAREX system in order to calculate the number of workers exposed to carcinogens in Costa Rica. It is the first use of CAREX outside Europe (TICAREX) in Costa Rica, Central America, for 27carcinogens and 7 groups of
pesticides thought to be of interest for the country, with separate estimations for men and women. The most frequent
agents of exposure for the 1.3 million workers of Costa Rica were solar radiation (333,000 workers); diesel exhaust
(278,000); paraquat and diquat (175,000); environmental tobacco smoke (71,000); hexavalent chromium compounds
(55,000); benzene (52,000); mancozeb, maneb and zineb (49,000); chlorothalonil (38,000); wood dust (32,000); quartz
(27,000); benomyl (19,000); lead and its inorganic compounds (19,000); tetrachloroethylene (18,000); and polycyclic
aromatic hydrocarbons (17,000). Owing to the different occupational distribution between the genders, exposures to
formaldehyde, radon and methylene chloride were more frequent than pesticides, hexavalent chromium, wood dust, and
quartz in women. Agriculture, construction, personal and domestic services, manufacture of wood products, mining,
forestry, fishing, manufacture of electrical products, and bars and restaurants were sectors with frequent exposures.
Substantial reduction of occupational and environmental exposures to these agents would significantly improve public and
occupational health. Reduction of occupational exposures is usually also followed by improvement of environmental
quality. Monitoring of exposures and health of workers and the general public is an essential element in the control of
environmental contamination and human exposures.
