|Title:||Comparative study of lung function in Iranian factory workers exposed to silica dust|
|Abstract:||The study compared lung function among 322 workers in pottery, ceramic, stone-cutter and stone-grinder factories in the west of the Islamic Republic of Iran. Concentrations of silica particles <2 microm were measured in the ambient air of factories. Forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC] were significantly lower in stone-grinders compared with pottery, ceramic or stone-cutter workers and a control group. No difference in lung function was found in pottery and stone-cutter workers with less than 20 years occupation compared with controls. The prevalence of respiratory symptoms in stone-grinders was higher than other workers. The concentration of silica particles of stone-grinder factories was 40-110 times higher than in ceramic and potteries factories. More attention is needed to ventilation systems and health care of stone-grinders|
