摘要
目的了解厦门市海沧区工业企业有机溶剂使用情况,检测生产环境空气中有机溶剂浓度,为职业卫生管理提供科学依据。方法对企业开展基线调查,采用Agilent GC 6890气相色谱仪,对33种有机溶剂的挥发成分进行定量分析。结果海沧区工业企业车间空气中挥发性有机溶剂高于限值的以二甲苯(72.4%)、苯(45.0)%、甲苯(59.0)%、乙酸丁酯(33.9%)、苯乙烯(30.7%)、乙酸乙酯(28.3%)、环己酮(25.0%)、戊烷(21.4%)为主,不同行业、不同工种车间空气中所含挥发性成分不同,同一作业点数种有机溶剂并存。结论厦门市海沧区工业企业使用有机溶剂比重较大,且成分复杂,应加强卫生监测,采取有效措施,防制有机溶剂急慢性中毒。
[ Objective] To learn the employment of organic solvents in the industrial enterprises of Haicang, to detect the concentration of organic solvents in the air of workplaces and provide scientific basis for occupational hygienic management. [ Methods] Base - line investigation was carried out on the enterprises; Agilent GC6890 gas chromatograph was adopted to conduct quantitative analysis on the volatilizing elements of 33 organic solvents. [ Results ] The volatilizing elements, namely, Xylene （72.45%）, benzene （72. 45% ）, toluene （61.91% ）, butyl acetate （33.93%）, styrene （30.68%）, ethyl acetate （28.33%）, cyclohexanol （25.0%） and pentane （21.43%） exceeded the maximum limit in the air of workplaces of Haicang; volatilizing dements differed between different industries and work types ; several organic solvents existed in the same workplace. [ Conclusion ] Organic solvents with complicated elements are widely used in the industrial enterprises of Haicang District of Xiamen ; effective measures should be taken to prevent organic solvent poisonings.
