Abstract:
Objective To analyze the detection situation and variation tendency of volatile components of organic solvents in enterprises in Longgang District, Shenzhen City. Methods A total of 368 enterprises using organic solvents in Longgang District, Shenzhen City from 2019 to 2022 were selected as the research subjects using judgment sampling method. And its 2 086 reports of occupational hazards monitoring on volatile components of organic solvents in workplaces from 2019 to 2022 were collected for analysis. Results Among the 2 086 organic solvent samples, the top 10 chemical substances in terms of detection rates were toluene, methanol, xylene, n-hexane, ethylbenzene, dimethoxymethane, dichloromethane, acetone, ethyl acetate and cyclohexane, with detection rates ranging from 16.73% to 29.72%. The detection rate of benzene in organic solvent samples from 368 enterprises decreased from 13.84% to 5.13% from 2019 to 2022 (P<0.01). The detection rate of trichlorethylene decreased from 3.58% to 0.45% (P<0.01), and the detection rate of dichloroethane decreased from 4.53% to 1.81% (P<0.01). However, the reduction in the detection rate of n-hexane was not significant (from 28.88% to 23.08%, P>0.05). Benzene had relatively high detection rates in yellow glue, super glue, and thinner (10.94%, 10.00%, and 8.45%, respectively). The detection rate of n-hexane was relatively high in super glue, cleaning agent and car wash liquids (90.00%, 61.84%, and 46.81%, respectively). The detection rate of trichlorethylene was relatively high in cleaning agent (3.95%), and the detection rate of dichloroethane was relatively high in super glue (40.00%). Conclusion From 2019 to 2022, the detection rates of traditional occupational hazards such as benzene, trichloroethylene, and dichloroethane in the volatile organic components used in Longgang District enterprises showed a downward trend.
