A purge and trap(P&T) method coupled with gas chromatography/mass spectrometry has been developed for the determination of 35 volatile organic compounds(VOCs) in natural drinking water,including Trihalomethan,Halogenated benzene,Benzene,Toluene,Ethylbenzene,and Xylenes(BTEX),Polycyclic aromatic hydrocarbons.The threshold were ranged from 0.05 to 0.17 μg/L,the recoveries of the 35 compounds spiked at 5 μg/L were between 86.5% and 113% with RSD(n=6) 1.6%~6.1%.There were 44 samples from markets and 5 samples from water source collected and analyzed.There were 8 compounds including 1,2-dichloroethane,chlorodibromomethane,bromodichloromethane,bromoform,benzene,chloroform,1,2,4-trimethylbenzene,toluene detected from the water samples,the detectable rate of chloroform were 49%.All concentration results obtained were within the requirements of relevant regulation value.None of VOCs was detected from the samples.
