Abstract

Introduction: Exposure to CRYSTALLINE SILICA dust can seriously threaten health of workers engaged in processes such as casting, stone crushing, grinding, construction activities, insulator manufacturing, and glassblowing and sandblasting. The aim of this study was to assess OCCUPATIONAL EXPOSURE to CRYSTALLINE SILICA and to determine the RISK of MORTALITY from SILICOSIS and LUNG CANCER in an insulator manufacturer.Material and Method: Air personal sampling was performed using 10 mm nylon cyclone and mixed cellulose ester (MCE) membrane filters (5 mm diameter, 0.8 mm pore size) for 60 male workers. Samples were prepared and analyzed according to the National Institute for Occupational Safety and Health (NIOSH) 7601 standard method. The RISK assessment of MORTALITY due to SILICOSIS resulting from CRYSTALLINE SILICA exposure was done by using model of Mannetje et al. for the period of 10 years. The MORTALITY rate of LUNG CANCER was determined using a linear regression model derived from the study Rice et al.Result: The highest and lowest exposure levels to silica were belonged to the packing unit (0.54±0.28 mg/ m3) and the furnace (0.02±0.01 mg/m3), respectively. CRYSTALLINE SILICA concentrations for all samples were higher than Threshold Limit Values (0.025 mg/m3) recommended by the American Conference of Governmental Industrial Hygienists (ACGIH). According to Mannetje et al. model, the cumulative exposure of 25% workers was in the range 0 to 0.99 that it represents 1 death per 1,000 people. The RISK of MORTALITY due to LUNG CANCER was obtained in the range of 7-94 persons per 1000 workers exposed to silica.Conclusion: In general, the geometric and arithmetic mean of CRYSTALLINE SILICA exposure was higher than threshold limit value for most of the subjects. For all workers of the insulator manufacturer, the RISK of SILICOSIS related MORTALITY was higher than 1/1,000 (unacceptable level of RISK). Predicting the LUNG CANCER MORTALITY from silica exposure indicated a high level of MORTALITY RISK among understudied workers.
