Abstract

Objective: To analyze the trends in occupational environmental hazardous factors and health damage, and to assess the degree of occupational health risks. Methods: A total of 1,733 occupational disease monitoring data points from workplaces collected by the Yangzhou Center for Disease Control and Prevention from January 2019 to December 2021 were selected to evaluate occupational hazard factors and occupational health risk levels. Results: Over the three-year period, there were 525 monitoring samples for dust exposure, with an exceedance rate of 1.71% (9/525); 791 monitoring samples for noise exposure, with an exceedance rate of 4.42% (35/791); and 417 monitoring samples for chemical toxins (exogenous) exposure, with an exceedance rate of 1.68% (7/417). A comprehensive evaluation of exceedance factors revealed that high-risk factors included silica dust and benzene, classified as Level 4, while medium-risk factors encompassed manganese and xylene, including their compounds, classified as Level 3. Conclusion: After long-term monitoring of multiple workplaces in the city, it was found that there were certain occupational hazard factors, specifically involving dust or noise, as well as related factors of chemical toxins. Among these, silica dust and benzene posed the highest risks, while manganese and xylene also carried relatively high risks. It is necessary to strengthen occupational disease prevention and management to reduce the occurrence risks.
