英文摘要	an analytical strategy for comprehensive screening of target and non-target volatile organic compounds (vocs) in surface water was developed, and it was applied to the analysis of vocs in water samples from daliao river. the target vocs were quantified using purge and trap-gas chromatography-mass spectrometry (p&t-gc/ms). among 20 water samples, 34 vocs were detected at least once. for the screening of non-target vocs, the double distillation apparatus was used for the pre-concentration of vocs prior to p&t-gc/ms analysis. subsequently, deconvolution software and nist mass spectral library were applied for the identification of the non-target compounds. a total of 17 non-target vocs were identified. the most frequently detected vocs (detection frequencies >80%) included toluene, benzene, naphthalene, 1,2-dichloroethane, 1,1,2-trichloroethane, and methyl tert-butyl ether. the distribution of vocs obviously varied according to the sampling sites. the total concentrations of vocs in water samples collected from the heavily industrialized cities (anshan and liaoyang) and the busy port city (yingkou) were relatively high. the top ten priority vocs, including naphthalene, 1,2-dichloroethane, o-xylene, 1,3-dichlorobenzene, tetrachloroethene, 1,2-dichlorobenzene, 1,2,4-trichlorobenzene, ethylbenzene, m-xylene, and p-xylene, were obtained by the ranking of the detected vocs according to their occurrence and ecological effects. these compounds should be given more attention in monitoring and drainage control strategies.
