	abstract = {Eighty-seven soil samples collected from North China were analyzed for Dechlorane Plus (DP). The concentrations of DP ranged from not detectable (ND) to 12.21 ng/g with a mean of 0.55 ng/g. The mean concentrations of total DP and syn-DP in four regions of North China were in the following order: Jingjin (Beijing and Tianjin) \&gt; Shandong \&gt; Shanxi \&gt; Hebei, while the mean concentrations of anti-DP in the four regions were in a different order: Shandong \&gt; Jingjin \&gt; Shanxi \&gt; Hebei. The mean f (syn) values for Jingjin (0.27), Hebei (0.24), and Shanxi (0.24) were close to 0.25, while the mean f (syn) value for Shandong (0.31) was closer to 0.35. In addition, the f (syn) value for Shandong was significantly higher (P \&lt; 0.01) than those of the other regions (Jingjin, Heibei, and Shanxi), indicating specific sources of DP. Syn-DP displayed a strong linear relationship with anti-DP (R (2) = 0.74), indicating that no obvious stereoselective process occurred in the soil of North China. Ordinary kriging was undertaken to map the spatial patterns of DP. High concentrations of DP in soils were present in south of Shanxi, central Hebei, south of Tianjin, and the south and northeast of Shandong, which were suggested to be connected with human activities such as e-waste dismantling.},
