目的 了解中山市工业企业使用有机溶剂的种类、行业分布,为防治有机溶剂中毒提供重要的依据。方法 使用气质联用仪(GC-MD)对129家企业使用的256种有机溶剂的挥发性成分进行定性分析。结果 中山市企业使用的有机溶剂挥发性成分以甲苯(37.5％)、丙酮(20.7％)、丁酮(18.0％)、乙酸乙酯(14.5％)、正己烷(10.2％)为主。不同行业使用的有机溶剂种类及所含挥发性成分不同。结论 中山市工业企业目前使用的有机溶剂成分比较复杂,今后应加强对这些企业的职业卫生监测,采取有效防护措施,防止有机溶剂中毒。
Objective To understand the types and distribution of organic solvents used by industrial enterprises in Zhongshan City and provide an important basis for the prevention and control of organic solvent poisoning. Methods Qualitative analysis was performed on the volatile components of 256 organic solvents used by 129 companies using gas chromatography-mass spectrometry (GC-MD). Results The volatile components of organic solvents used by Zhongshan enterprises were mainly toluene (37.5%), acetone (20.7%), methyl ethyl ketone (18.0%), ethyl acetate (14.5%) and n-hexane (10.2%). Different industries use different types of organic solvents and volatile components. Conclusion The current use of organic solvents in industrial enterprises in Zhongshan City is rather complicated. Occupational health monitoring should be strengthened for these enterprises in the future and effective prevention measures should be taken to prevent organic solvents from poisoning.
