Title Exposure assessment for nitrogen oxides and carbon monoxide in German hard coal mining
Bibliographic information Nov. 2009, Vol.92, No.10, p.1267-1279. Illus. 44 ref.
Abstract Exposures of German hard coal miners to nitrogen monoxide (NO), nitrogen dioxide (NO2) and carbon monoxide (CO) were measured in a cohort of 1369 miners from two German coal mines, and the data were used to estimate long-term exposures. For all three components, time weighted 8h shift values were determined for typical groups of coalminers according to the European measurement standard. An expert panel from the coal mining company estimated major potential long-term changes in the exposure situation. The main sources of nitrogen oxides and carbon monoxide were diesel engines, while blasting fumes contributed to a lesser degree. The findings concerning CO are discussed in a separate publication. Among diesel engine drivers, current 8h average exposures were 1.35ppm for NO and 0.21ppm for NO2. For blasting workers, the corresponding values were 0.84ppm and 0.014ppm. By applying these data and the estimates of experts concerning retrospectives, cumulative exposures for NO and NO2 were determined from 1974 until 1998. Implications of these findings are discussed.
