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 used reagents, n-hexane, toluene, ethanol and acetone, showed higher concentrations in laboratories air, about 10~1000 times higher than outdoors. High levels of toluene, ethylbenzene and xylenes were found in some waiting areas of hospitals, which would draw more attention.
