Title Risks of respiratory disease in the heavy clay industry
Bibliographic information Feb. 1999, Vol.56, No.2, p.124-133. Illus. 28 ref.
Abstract Little information is available on the quantitative risks of respiratory disease from quartz in airborne dust in the heavy clay industry. The aims of the present cross-sectional study were to determine among workers in the industry (a) their current and cumulative exposures to respirable mixed dust and quartz; (b) the frequencies of chest radiographic abnormalities and respiratory symptoms; (c) the relations between cumulative exposure to respirable dust and quartz, and risks of radiographic abnormality and respiratory symptoms. Although most quartz concentrations at the time of this study were currently below regulatory limits in the heavy clay industry, high exposures regularly occurred in specific processes and occasionally among most occupational groups. There are small risks of pneumoconiosis and respiratory symptoms in the industry, although frequency of pneumoconiosis is low in comparison to other quartz exposed workers. Topics: air sampling; brick and tile industry; quartz; chest radiography; clay products; cross-sectional study; dust measurement; exposure evaluation; job-exposure relation; non-metallic mineral products industries; opacities; pneumoconiosis; respirable dust; respiratory diseases.
