Ventilatory capacities of 73 Libyan men working in the Asbestos-Cement Pipe factory in Jenzur, a residential area near Tripoli, Libya and those of 73 age-matched healthy Libyan men unexposed to asbestos were determined. The mean values of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV-1) for men unexposed to asbestos were 3.89+-0.084 and 3.64+-0.082 liters respectively. The respective values for men exposed to asbestos were 3.62+-0.082 and 3.29+-0.097 liters. Thus, there has been a significant decrease in the ventilatory function of the men exposed to asbestos as compared with age-matched unexposed counterparts. Duration of exposure is an important factor in the onset of pulmonary dysfunction as indicated by decreased vital capacity.
