Resumen |
In 1984-1985, chest radiography, spirometry tests, and questionnaires on work history, respiratory symptoms, and smoking history were administered to 1,061 white males employed at 31 coal cleaning plants and strip coal mines in an anthracite coal region of the US. The prevalence of radiographic evidence of ILO category 1 or higher small opacities was 4.5% in 516 men who had never been employed in a dusty job other than in surface coal mining. Among these 516 workers, all 4 cases of ILO radiographic category 2 or 3 rounded opacities and 1 case of large opacities had been employed as a highwall drill operator or helper. The prevalence of category 1 or higher opacities increased with tenure as a highwall drill operator or helper. Radiographic evidence of small rounded opacities, dyspnoea, and decreases in FEV1.0, FVC, and peak flow were significantly related to tenure at drilling operations after adjusting for other factors. However, tenure in coal cleansing plants and other surface coal mine jobs was not related to significant health effects. The excess prevalence of small, rounded opacities in anthracite surface coal mine drillers suggests that quartz exposures have been increased. Average respirable quartz concentrations at surface coal mine drilling operations should be evaluated to determine whether exposures are within existing standards, and dust exposures should be controlled. |
