目的了解上海市宝山区苯系物作业企业职业危害现状,为开展防治工作提供依据。方法对该类企业进行抽样调查,收集劳动者职业健康检查资料,检测车间苯系物浓度与工人个体接触水平,并对结果进行统计学分析。结果不同工龄组工人血常规各项结果差异均无统计学意义(P>0.05)。苯、甲苯作业场所检测与个体采样结果均未超标,作业场所二甲苯检测点不合格率5.6%,1名工人二甲苯个体采样结果超标。16家企业职业卫生工作总费用209.8万元,接害劳动者人均职业卫生经费3 240元。结论应继续加强宝山区企业职业卫生监督管理,切实保护苯系物作业工人职业健康。 Objective To understand the status quo of occupational hazards of benzene-based material operating enterprises in Baoshan District of Shanghai and provide the basis for prevention and control work. Methods A sampling survey of such enterprises was conducted. Occupational health examination data of laborers were collected, the concentration of benzene series in the workshop and individual exposure level of workers were measured, and the results were statistically analyzed. Results There was no significant difference in the results of blood routine among workers of different seniority (P> 0.05). Benzene, toluene, workplace testing and individual sampling results were not exceeded, the workplace xylene test point unqualified rate of 5.6%, 1 worker xylene individual sampling results exceeded.
