Respirable Crystalline Silica Exposure-Response Evaluation of Silicosis Morbidity and Lung Cancer Mortality in the German Porcelain Industry Cohort
This article, which appeared in the Journal of Occupational and Environmental Medicine, quantifies silicosis and lung cancer risks among porcelain workers occupationally exposed to crystalline silica. Authors Kenneth A. Mundt,* Thomas Birk,* William Parsons, Elisabeth Borsch-Galetke, Klaus Siegmund, Karyn Heavner and Karlheinz Guldner tracked 18,000 German porcelain workers from 1985-2005 for the occurrence of silicosis and lung cancer. Risks were compared by categories of exposure based on a quantitative assessment.** Exposures over 4 mg/m3-years or average working exposure over 0.15 mg/m were strongly associated with silicosis, suggesting a risk threshold, but were unrelated to lung cancer risks.
