Abstract

Background: In recent years, many national and international expert groups have considered specific improvements in risk assessment of chemical pollutants. This study has considered to assess the risk of workers exposed to the air pollutants followed by inhalation exposure in an automobile manufacturing in Iran. Methods: A cross-sectional research was done in. Methods number 1501 and 7602 of the National Institute of occupational safety and Health (NIOSH) were used for sampling and analysis of compounds BTEX and silica in the air. A total of 40 samples of compound BTEX were taken and analyzed by Gas Chromatography-Flame Ionization Detector (GC-FID). A total of 6 samples of silica were collected during the campaign. Silica analyses were performed by using visible spectrophotometry. Risk ranking was calculated using the hazard and exposure rate. Finally, the relative risk of blood cancer caused by exposure to benzene was estimated. Results: The result demonstrated that, workers were exposed to 5 chemicals including silica, benzene, toluene, ethyl-benzene, and xylene during their work in manufactory. Among the pollutants in the breathing zone of workers, silica and benzene were hazardous chemicals at high risk level. Following the estimation of relative risk of blood cancer caused by exposure to benzene, workers cumulative exposure to benzene was obtained to be 23.1 ppm per year and the capture relative risk was 1.1. The significant relationships were also seen between the workers exposed to benzene in both age and work experience, so that, degree of exposure decreased steadily with increasing age and experience (P<0.001). Conclusions: This research demonstrated that, benzene and silica had the highest exposure risk in the automobile manufacturing. Also, painting hall workers were directly exposed to benzene possibly increase the blood cancer risk. Therefore, an essential education and occupational protection programs needed to be considered in order to reduce risk assessment associated with the chemicals in industries like automobile manufacturing.
