Quartz exposure in the slate industry in northern norway

摘要

In this study we have measured exposure levels to quartz in different parts of the slate industry in Alta, Northern Norway. Full shift personal samples were collected from the breathing zones of Outdoor and indoor workers in the slate quarries and a slate factory. The quartz content of Respirable dust was between 7 and 41/100. The slate factory had the lower quartz levels although 41/100 of total and 73/100 of respirable samples were above the Norwegian TLV for quartz. The Average concentration of total quartz in the slate factory was 0.27 mg/m~3 and the average con- Centration of respirable quartz was 0.12 mg/m~3.
