چکیده مقاله:
For evaluation of respiratory capacities, the amount of VC(Vital Capacity), FVC (Forced Vital Capacity), FEV (Forced Expiratory Volume in one second) were measured in 221 pottery, ceramic, slip, molder workers in Lalejin, Hamadan, Iran. The results were compared with respiratory capacities of 61 people in Lalejin that occupy to business which are not exposed to any particle of quartz. Statistical tests showed the mean amount of respiratory volume in pottery and ceramic workers with less than 20 years occupy, was not different from the control group but in workers with more than 40 years old and more than 20 years occupy to ceramic and pottery, VC, FVC, FEVwere different from the control group. The proportion of FEV/VC is lower than 75%. Concentration of particles were measured in different workplaces ambient. The results showed that concentration of dust in ceramic and pottery workshops were more than slipper and molder workshops.
