AB  - Vehicular emissions have become a primary anthropogenic source of urban 
      atmospheric volatile halogenated hydrocarbons (VHCs) with the rapid increase of 
      vehicle population, while characteristics of the VHC emissions from different 
      vehicles were rarely systematically investigated. In this study, the on-road 
      tailpipe emissions were sampled from seven in-use vehicles, including two 
      light-duty gasoline vehicles (LDGV), three light-duty diesel trucks (LDDT), one 
      heavy-duty diesel truck (HDDT), and a liquefied petroleum gas-electric hybrid bus 
      (LPGB), using a portable emission measurement system (PEMS) combined with summa 
      canisters, and 35 individual VHC species were identified by a gas chromatography 
      mass spectrometry detector (GC-MSD). Results showed that VHC emissions under 
      urban driving conditions were much higher than those on the suburban roads and 
      highways. The VHC emission factors of LDGV were 1.2 +/- 0.34 mg/km and 3.6 +/- 1.5, 
      6.8 +/- 0.89, and 1.6 +/- 0.28 mg/km for LDDT, HDDT, and LPGB, respectively. For the 
      LDGV, chlorobenzene, 1,2-dichloroethane, and hexachlorobutadiene were the top 
      three VHC species. 1,2-Dichloroethane, trichloromethane, and methyl chloride were 
      the main VHC constituents in the LDDT. Chlorobenzene was the most abundant VOC 
      species for the HDDT, followed by 1,2-dichloroethane and 1,4-dichlorobenzene. The 
      major species for LPGB were 1,2,4-trichlorobenzene, carbon tetrachloride, and 
      benzyl chloride. The major tailpipe VHC species obtained in this study were 
      partial consistent with previous studies with different test methods. The results 
      provide an initial evaluation of the tailpipe VHC emissions, which may provide 
      experimental data support for the refined source apportionment of atmospheric 
      VHCs and the control of vehicular VHCs.
