ABSTRACT

El sistema europeo de datos CAREX (CARcinogen Exposure) considera la fuerza laboral de un país agrupada en 55 sectores económicos según la Clasificación Internacional de Actividades Económicas de las Naciones Unidas, segunda revisión de 1968, y mediante la aplicación de proporciones de trabajadores expuestos a partir de datos generados en estudios de higiene industrial para 139 agentes carcinógenos, los convierte en fuerza laboral expuesta y número de trabajadores expuestos a agentes carcinogénicos, según rama de actividad. En este artículo se describe una modificación y extensión del sistema CAREX para calcular los números de trabajadores expuestos a agentes cancerígenos y plaguicidas en Costa Rica. Esta primera aplicación de CAREX fuera de Europa (TICAREX) fue realizada en Costa Rica, Centroamérica, para 27 agentes cancerígenos y 7 grupos de plaguicidas, considerados de interés para el país, realizando estimaciones por separado para mujeres y hombres. Los agentes cancerígenos más frecuentes a los que se expone la fuerza laboral de Costa Rica de 1.3 millones fueron la radiación solar (333,000 trabajadores), las emisiones de diesel (278,000), paraquat y diquat (175,000), el humo de tabaco ambiental (71,000), los compuestos de cromo hexavalente (55,000), el benceno (52,000), mancozeb, maneb y zineb (49,000), clorotalonil (38,000), el polvo de madera (32,000), el cuarzo (27,000), benomil (19,000), el plomo y sus compuestos inorgánicos (19,000), tetracloroetileno (18,000), y los compuestos aromáticos policíclicos (17,000). En los hombres, la distribución se mantuvo muy ajustada a los anteriores rangos, sin embargo en las mujeres, debido a su diferente distribución en los sectores, el formaldehído, el radón y el cloruro de metileno superaron a los plaguicidas, el cromo (VI), el polvo de madera y el cuarzo. La agricultura, la construcción, los servicios personales y domésticos, el transporte terrestre y acuático y los servicios asociados al transporte, la fabricación de productos cerámicos y similares, la manufactura de productos de madera, la minería, la silvicultura, la pesca, la fabricación de maquinaria y aparatos eléctricos, bares y restaurantes fueron sectores de donde las exposiciones son frecuentes. Una reducción drástica de exposiciones laborales y ambientales a estos agentes daría por resultado mejoras sustanciales en los niveles de salud pública y ocupacional. La vigilancia de las exposiciones laborales y de la salud en el trabajo son esenciales para el control de la contaminación y de las exposiciones a los agentes cancerígenos


The European data system CAREX takes the workforce of a country grouped into 55 economic sectors according to the International Economic Activity Classification 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

ABSTRACT

Pesticides are an extensively documented occupational and environmental hazard in Central America. Yet, severe problems persist. Toxic pesticide use in the Region increased during 1985-1999. High exposure levels and ineffectiveness of personal protective equipment evidence the difficulties for risk reduction. Acute poisonings remain a severe problem. Delayed and/or long-lasting health effects include dermatoses, cancer, and genotoxic, neurotoxic, and respiratory effects. The use of hazardous pesticides persists through deficiencies in government-driven assessment and risk management; excessive focus on regional harmonization; short-term economic interests; strong links between industry and governments; aggressive marketing; weak trade unions; and failure of universities to reach decision makers. Regulation based on local data is lacking. An agreement of the Ministries of Health for restricting the most toxic pesticides in Central America has potential for progress. The most effective way to reduce risk is to greatly reduce pesticide use. Actions needed include development of multidisciplinary strategies for local studies on health and environmental impact of pesticides; development of sustainable nonchemical agricultural technologies; evaluation of interventions; extending and sharing of expertise within the Region; strengthening of unions and communities; and redefining the role of industry toward development of safer products, with responsible marketing and reliable information.
