متن کاملRespiratory effects of occupational exposure to tobacco dust.
The ventilatory capacities of 195 tobacco factory workers exposed to tobacco dust and 190 Libyan men not exposed to tobacco dust were measured. In both groups, the forced vital capacity (FVC) and forced expiratory volume in 1 s were found to be correlated with age, stature, sitting height and body surface area. Those exposed to tobacco dust have decreased ventilatory capacity values as compared...
متن کاملA 20-year follow-up study on chronic respiratory effects of exposure to cotton dust.
In order to evaluate chronic effects of long-term exposure to cotton dust on respiratory health, and the role of dust and endotoxin, longitudinal changes in lung function and respiratory symptoms were observed prospectively from 1981 to 2001 in 447 cotton textile workers, along with 472 silk textile controls.
