摘　　要：【目的】了解上海市金山区涉苯及苯系物的工作场所中苯、甲苯、二甲苯的浓度水平,为政府制定重点职业病防控策略提供依据。【方法】对2016—2021年金山区涉苯及苯系物企业进行个体采样,通过作业场所空气采样和实验室检测对苯及苯系物的监测结果进行统计分析。【结果】2016—2021年共监测80家企业,总合格率为87.50%,历年合格率先下降后上升,差异无统计学意义(P>0.05)。共采集个体387人次,总合格率为95.61%,检出率为73.38%(284人次)。其中苯、甲苯、二甲苯的检出率分别为6.46%、29.97%、36.95%,超标率分别为1.03%、0.26%、3.10%。企业中金属制品行业超标率最高(19.05%);个体中印刷和记录媒介复制业超标率最高(10.26%)。【结论】金山区苯及苯系物检测合格率较高,检出率也较高。金属制品行业、印刷和记录媒介复制业的苯及苯系物超标率较高。[Objective]To understand the concentration levels of benzene,toluene and xylene in the workplaces of enterprises involved in benzene and benzene series in Jinshan District,and to provide the basis for the government to formulate key occupational disease prevention and control strategies.[Methods]From 2016 to 2021,enterprises involved in benzene and benzene series were sampled individually,and the monitoring results of benzene and benzene series were statistically analyzed through workplace air sampling and laboratory detection.[Results]From 2016 to 2021,a total of 80 enterprises were monitored,and the total passing rate of individual monitoring was 87.50%,which decreased first and then increased.The difference was not statistically significant.A total of 387 individuals were sampled with a total passing rate of 95.61%and a detection rate of 73.38%(284 individuals).The detection rates of benzene,toluene and xylene were 6.46%,29.97%and 36.95%,respectively.The exceedance rates were 1.03%,0.26%and 3.10%,respectively.Among the companies exceeding the standard,the metal products industry had the highest rate of exceedance(19.05%).For individuals,those working in the printing and recording media reproduction industry had the highest rate of exceedance(10.26%).[Conclusion]The passing rate and detection rate of benzene and benzene series are relatively high in Jinshan District.The metal products industry and the printing and recording media reproduction industry have a higher exceedance rate of benzene and benzene series.
