CORREA, Maria Juliana Moura  and  SANTANA, Vilma Sousa. Occupational exposure to benzene in Brazil: estimates based on an occupational exposure matrix. Cad. Saúde Pública [online]. 2016, vol.32, n.12, e00129415.  Epub Dec 22, 2016. ISSN 1678-4464.

This study estimates the number of exposed workers and the prevalence of occupational benzene exposure in Brazil. Due to the lack of available local measurements for the study, data were used from an occupational exposure matrix, the Finnish National Job-Exposure Matrix (FINJEM), which covers proportions of individuals exposed to benzene, calculated as environmental measures. In Brazil, the 2010 Demographic Census identified 86,353,839 workers in the workforce and employed. Applying the FINJEM parameters, an estimated 7,376,761 (8.5%) belonged to potentially exposed occupational groups, while 770,212 were considered exposed to benzene, corresponding to an occupational group-weighted prevalence of 0.9%, higher in men (1.1%) than in women (0.6%). Exposed individuals were concentrated in the category of Machine and Motor Operators and Mechanics (62%). The number of exposed and prevalence of occupational exposure to benzene are high, even when compared to Finnish parameters, suggesting the need for monitoring and control of this carcinogen in Brazil.
