Abstract

In this study, 99 WORKERs of stone-cutting and -grinding in Hamadn Suburbs were studied; their vital capacity (VC), forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were all measured using a spirometer. The results were compared with those of the control group, 65 WORKERs exposed to no pollution in their workplace. The relevant data including age, job, smoking and so on were gathered through a questionnaire. The results indicated that the FEV1 and FEV1/NC of stone-grinding WORKERs differed significantly from those of the control group. However, the VC, FVC and FEV1 of the stone-cutting WORKERs did not show any significant difference with the control group. Distribution of particles in the AMBIENT AIR was 5-10 times higher than the threshold level recommended by the National Institute of Occupational Safety and Health. Therefore, it seems compulsory to put in ventilation systems in workplaces and also to put the WORKERs under constant care and periodical medical examinations.
