DISTRIBUTION OF DDTs IN URBAN SOILS OF BEIJING, CHINA

摘要：

Dichlorodiphenyltrichloroethanes (DDTs) in urban soil samples (0～20cm) from Beijing were determined using a Varian CP-3800 gas chromatograph equipped with a 63Ni electron capture detector (GC-63Ni ECD) system. The total DDTs concentrations in the soil samples varied from 0.03 to 1282.58 ng/g, with an average of 68.14±189.46 ng/g. DDTs concentration showed a decreasing trend from the centre to the suburb of the city, and it increased with the age of the urban area. The DDTs concentration in CL was much higher than the other five types of land use, which was due to the usage of DDTs to protect vegetation in CL.
