| 摘 要： | 分别采集了医院和实验室环境空气样品,通过GC-MS/FID对样品进行定性分析.共定性检测出116种挥发性有机物(VOCs).在这两类环境中检出频次较高的VOCs物种包括乙烷、丙烷、正丁烷等烷烃;乙烯、丙烯、1-丁烯等烯烃;苯、甲苯、乙苯等芳香烃;氯甲烷、二氯甲烷等卤代烃和丙酮等含氧有机物.在实验室中经常使用的试剂如正己烷、甲苯、乙醇、丙酮等呈现较高的水平,高于室外1~3个数量级.在医院的部分候诊区中检出较高浓度的甲苯、乙苯、二甲苯,需要引起关注.

| Abstract: | Air samples were collected at hospitals and laboratories,using SUMMA canisters.116 kinds of VOCs were identified from indoor and outdoor air of hospitals and laboratories by the pre-concentrator GC/MS system.Alkanes such as ethane,propane and n-butane,alkenes such as ethene,propene and 1-butene,aromatics such as benzene,toluene and ethylbenzene,halohydrocarbons such as chloromethane and dichloromethane,and OVOCs such as acetone and acetaldehyde,were detected frequently from indoor air samples.Those common u... |
