Abstract |
The objective of this study was to gain a more detailed knowledge of the relations between exposure to quartz and risks of silicosis in coal miners. Detailed data on working times at different quartz concentrations were combined to produce exposure profiles for 371 male miners aged 50-74 who had provided a chest radiograph. Results indicated that cumulative quartz exposure at higher concentrations resulted in proportionally greater risks of abnormalities. A cumulative exposure of 1g.h/m3 at quartz concentrations greater than 2mg/m3 was estimated to have equivalent risks to 3g.h/m3 at lower concentrations. Quantification of the risks of silicosis should take account of variations in quartz exposure intensity, particularly for exposure to concentrations of greater than 1 or 2mg/m3, even if exposure is for relatively short periods. The risks of silicosis over a working lifetime can rise dramatically with even brief exposure to such high quartz concentrations. |
