Analytical Performance Criteria Measurements of Silica in Air: Reliability at New and Proposed Occupational Exposure Limits

摘要

In many countries, improvements in workplace control standards have reduced the scale of reported cases of silicosis. Some countries have also banned silica from use as an abrasive blasting material because this task using sand was identified as a major cause of silicosis cases. However, even where national legislation has for many years required the employer to implement control standards, there remains a persistent level of reported silicosis cases. This failure to eliminate or reduce the incidence of silicosis at the current occupational exposure standards has increased the pressure for a reduction in the exposure limits and for tighter controls.
