目的了解深圳市某区2 009-2 01 3年企业作业场所苯系物检测情况,为制订职业病防治策略提供科学依据。方法采用随机抽样方法 ,对某区存在苯系物职业危害因素的企业进行采样,按G B Z/T 1 60.4 2-2 004采用溶剂解吸-气相色谱法进行测定。结果根据检测结果 ,对不同企业、不同年份苯系物含量进行统计学分析,苯系物含量合格率逐年上升,不同经济性质行业苯系物合格率无明显差异。结论某区作业场所2 009-2 01 3年苯系物检测合格率逐年提高,苯系物超标主要以甲苯超标为主,不同经济性质的企业苯系物检测合格率无明显差异,应加强对企业监督指导,加强防护措施和工艺改进。
Objective To understand the detection of benzene series in the workplace of 2 009-2 01 3 in a certain area of Shenzhen City and provide a scientific basis for formulating prevention and control strategies of occupational diseases. Methods A random sampling method was used to sample enterprises with occupational hazards of benzene series in a certain area. The samples were determined according to G B Z / T 1 60.4 2-2 004 by solvent desorption-gas chromatography. Results Based on the test results, the benzene content in different enterprises and years was statistically analyzed. The passing rate of benzene series substances increased year by year. There was no significant difference in the passing rate of benzene series in different economic sectors. Conclusion The passing rate of benzene series test in the workplace of 2 009-2 01 3 in a certain district is increasing year by year. The main ones of benzene series exceeding the standard are mainly toluene exceeding standard. There is no obvious difference in the passing rate of benzene series of enterprises with different economic characteristics. Supervision and guidance of enterprises, strengthen protective measures and technological improvements.
