【Abstract】 The studying area is the recharge area of shallow groundwater. The results indicate that the chloroaliphatic hydrocarbons (CAHs) from landfill leathates is mainly distributed in the middle of the area. The seasonal characteristics of CAHs occurrence and concentration can be well correlated with the distance and the age of landfills, which decrease with the distance and increase with the age. The article discusses the characteristics of CAHs in groundwater contaminated from landfill leachates in two aspects: vulnerability to contamination of groundwater and contamination mechanism.更多还原
