| Resumen |
The US National Institute for Occupational Safety and Health (NIOSH) surveyed 491 mines across the country during the National Occupational Health Survey of Mining (1984-89). The aim of the survey was to inventory and characterize all of the health-related agents to which US miners are potentially exposed. This report presents the potential exposure data for quartz measured in bulk dust samples. The bulk dust samples that were analyzed from the 491 mines yielded an average 14% of quartz. Surface labourers in coal mine occupations and bin pulley/truck loader workers in metal/non-metal occupations were potentially exposed to bulk dust containing the highest average percentage quartz (19% and 33%, respectively) compared to other occupations. The highest average percentage quartz (22%) was found in surface pit coal mines. Out of 272,000 miners represented in the study, 78,000 (29%) were potentially exposed to bulk dust containing an average of quartz greater than 12%. |
