%X To obtain the vaporization rule of organic pollutants in a young landfill leachate, we conducted normal evaporation and gas-carrying evaporation experiments, analyzing TOC and volatile fatty acids (VFAs) of batch condensate. The results showed that TOC in condensates declined when pH was 4, whereas it presented a contrary trend when pH was 7. Variation of VFAs except acetic acid in condensates was similar to that of TOC. The more complicated the chemical construction of VFAs was, the greater the relative rate of vaporization was. The results indicated that the organic matter in condensate from young landfill leachate mainly consisted of VFAs. The quantity change of carried gas didn't distinctly affect the vaporization rule of organic matter in young landfill leachate.
