||Quantitative crystalline silica exposure assessment for a historical cohort epidemiologic study in the German porcelain industry
||Sep. 2010, Vol.7, p.516-528. Illus. 31 ref.
||A time-dependent quantitative exposure assessment of silica exposure among nearly 18,000 German porcelain workers was conducted. Over 8000 historical industrial hygiene (IH) measurements with original sampling and analysis protocols from 1954-2006 were obtained from the German ceramics industry association and used to construct a job exposure matrix (JEM). Average silica concentrations were derived for six primary similar exposure groups for 1938-2006. Over 40% of the cohort accumulated <0.5 mg; just over one-third accumulated >1 mg/m3-years. Nearly 5000 workers had cumulative crystalline silica estimates >1.5 mg/m3-years. Similar numbers of men and women fell into each cumulative exposure category, except for 1113 women and 1567 men in the highest category. Over half of those hired before 1960 accumulated >3 mg/m3-years crystalline silica compared with 4.9% of those hired after 1960. Among those ever working in the materials preparation area, half accumulated >3 mg/m3-year compared with 12% of those never working in this area. Other findings are discussed.
