This paper deals with status of eight heavy metals (Hg, Cd, Pb, As, Cu, Cr, Ni and Zn) in the soil from the Fengrun region, Tangshan City, Hebei province and quality evaluation of the soil. The result of the investigation indicates that: 1. the study area soil is neutral — alkaline — strongly alkaline;2. the organic matter content is widespread low;3. high concentrations of all heavy metals distribute in the localities where there are intensive mankind's activities. The most outstanding localities are Xiaodaodi village, Shawoxin village, Puzhuangzi village, Qianxinzhuang village, Xuezhuang village and Hancheng town. The main pollutant exhausting enterprises in study area are Guofurunxing Milk Ltd., the hennery, Jinxiang chemical fibre factory, Tangshan Fuming steel Ltd.
