Pneumoconiosis risk assessment method based on cumulative dust exposure

Abstract

Abstract:

In order to reduce the risk of pneumoconiosis for workers with different dust exposure experiences, a risk assessment method was proposed. Firstly, dust types were identified, and dust exposure in workplace and cumulative dust exposure of workers were evaluated, and dose-response relationship between dust and pneumoconiosis risk were determined. Then, current pneumoconiosis risk, risk after a period of continued exposure to dust, increase of such risk, and its growth rate were assessed by using current values and increment values of cumulative prevalence as risk assessment indexes. Finally, with 15 coal miners as examples, pneumoconiosis risk assessment was carried out by utilizing the assessment method. The results show that the proposed method is intuitive and effective. And pneumoconiosis risk monotonously increases along with the cumulative dust exposure. The smaller the exposure is, the more obvious effect of dust prevention intervention measures will have in reducing relative risk.

Key words: cumulative dust exposure, dose-response relationship, pneumoconiosis, risk assessment, uncertainty
