Abstract
ObjectiveTo understand the concentration levels of benzeneï¼ toluene and xylene in the workplaces of enterprises involved in benzene and benzene series in Jinshan Districtï¼ and to provide the basis for the government to formulate key occupational disease prevention and control strategies.MethodsFrom 2016 to 2021ï¼ enterprises involved in benzene and benzene series were sampled individuallyï¼ and the monitoring results of benzene and benzene series were statistically analyzed through workplace air sampling and laboratory detection.ResultsFrom 2016 to 2021ï¼ a total of 80 enterprises were monitoredï¼ and the total passing rate of individual monitoring was 87.50%ï¼ 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% ï¼284 individualsï¼. The detection rates of benzeneï¼ toluene and xylene were 6.46%ï¼ 29.97% and 36.95%ï¼ respectively. The exceedance rates were 1.03%ï¼ 0.26% and 3.10%ï¼ respectively. Among the companies exceeding the standardï¼ the metal products industry had the highest rate of exceedance ï¼19.05%ï¼. For individualsï¼ those working in the printing and recording media reproduction industry had the highest rate of exceedance ï¼10.26%ï¼.ConclusionThe 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.
