目的了解佛山市所辖企业工作场所有机溶剂污染状况,为职业卫生监测及管理提供依据。方法使用气质联用仪测定来自24家企业的98份有机溶剂挥发性成分。结果 98份样品中,有机溶剂挥发性成分含有正己烷、苯、三氯乙烯、1,2-二氯乙烷及三氯甲烷。正己烷检出率为13.4%,苯检出率为4.7%,三氯乙烯为1.6%,1,2-二氯乙烷为1.7%,三氯甲烷未检出。结论佛山市企业有机溶剂使用情况不容乐观,大多数使用含有公认的对人体有害的高毒物质。企业在生产过程中应明确所选有机溶剂的成分,尽量选用无毒或低毒物质代替有毒或高毒物质。
Objective To understand the organic solvent pollution in the workplace of enterprises under the jurisdiction of Foshan and provide the basis for occupational health monitoring and management. Methods 98 volatile organic compounds from 24 companies were measured by GC / MS. Results In 98 samples, the volatile components of organic solvents contained n-hexane, benzene, trichlorethylene, 1,2-dichloroethane and trichloromethane. The detection rate of n-hexane was 13.4%, the detection rate of benzene was 4.7%, trichlorethylene was 1.6%, 1,2-dichloroethane was 1.7%, chloroform was not detected. Conclusion The use of organic solvents in Foshan enterprises is not optimistic, and most of them use highly toxic substances that are recognized to be harmful to human beings. Enterprises in the production process should be clearly selected organic solvent composition, try to use non-toxic or low toxic substances instead of toxic or highly toxic substances.
