Abstract: Objective By analyzing the monitoring results of occupational hazard factors in workplaces of Huangshi City in 2021,to provide the theoretical basis for local occupational disease prevention. Methods The monitoring data of occupational hazard factors in workplaces of Huangshi City in 2021 were extracted from the Monitoring system for occupational hazards in the workplace,which is the subsystem of China disease control and prevention information system,and the data were analyzed. Results In 2021,the detcetion of occupational hazard factors in workplaces were conducted in 150 enterprises in Huangshi City. There were 42 495 workers in 150 enterprises,19 597 people were exposed to occupational hazard factors,and the exposure rate was 46.12%. There was statistically significant difference in the exposure rate of occupational hazard factors among different areas （P<0.01）,and the exposure rate in Xialu District was the highest. There was statistically significant difference in the exposure rate of occupational hazard factors among enterprises of different sizes（P<0.01）,and the exposure rate in microenterprises was the highest. There was statistically significant difference in the exposure rate of occupational hazard factors among different industries（P<0.01）,and the exposure rate in manufacturing industry was the highest. There was statistically significant difference in the exposure rate among different types of occupational hazard factors（P<0.01）. The over standard rate was 18.31% among 295 detected points in dust places,while the over standard rate was 18.97% among 290 detected points of post. The over standard rate was 5.26% among 228 detected points for chemical hazard factors,while the over standard rate was 25.00% among 40 detected points of post. The over standard rate was 41.10% among 798 detected points in dust places,while the over standard rate was 9.09% among 11 detected points of post. Conclusion There are a large number of people exposed to occupational hazard factors in Huangshi City,and the over standard rate of on-site detection is high,therefore,it is necessary to strengthen the supervision of relevant enterprises and urge them to implement occupational hazard prevention measures.
