Abstract: Concentrations of halohydrocarbons in surface and ground water samples from Shenyang area were determined. The contamination levels and distribution characteristics of halohydrocarbons were discussed. The detectable rates of water samples from Hunhe River and Puhe River were low (about 33.3%, dominated by dichloromethane) and that of the halohydrocarbons in Xihe River and Shenfu Irrigation Channel were high with 13 halohydrocarbons detected. Concentrations of some individual halohydrocarbons from 6 of 30 surface water sampling sites, exceeded the national hygienic standard values for drinking water. The concentration of 1,2dichloroethane (101.1 μg/L) from one of 13 sampling wells exceeded the national hygienic standard value for drinking water. Highest concentration values occurred at the upstream of Shenfu Irrigation Channel, the upstream and midstream of the Xihe River, possibly due to the waste discharge from chemical plants along the rivers. The sand layer in the soils could provide transportation of pollutants from the polluted rivers, which could be potential threat to ecosystem and local population.
