Methods Ten stone processing enterprises in a street of Shenzhen City were randomly selected for occupational health investigation, detection and analysis. Results The free silica content in the dust of the 10 stone processing enterprises was 11.0%-30.9%, and the silica dust (exhaled dust) of each post did not exceed the standard. The noise was mainly high-frequency noise, and the over-standard rate ofintensity detectionwas 84.4%. Benzene was the most detected component of volatile organic compounds, which mainly existed in curing agents. The detection results of occupational hazards revealed that the detection rate of 1, 2-dichloroethane was the highest, reaching 52.0%. The results of occupational health examination displayed that the abnormal rate of pure tone audiometry was 94.1%. Conclusion The occupational hazards of stone processing industry are serious, and noise is the key control point of occupational hazards. It is necessary to strengthen the support and supervision of occupational health in stone processing enterprises, and urge workers to take personal protective equipments well. The enterprises should strengthen source control of organic solvents and occupational health management.
