Abstract:Investigation and assessments of pollutions of heavy metals such as Zn、Pb、Ni、Cu、Cr、As and Hg in outer suburbs of Guangzhou City were carried out. The present polluted degree and potential ecological hazards of heavy metals were evaluated by the nemerow index and the potential ecological risk index (RI). The heavy metal concentrations of 26 soil samples were higher than the local background value, some indicators exceed the national recommended environmental quality secondary standard for soils, and with the uneven of space distribution. The mean nemerow synthesis index of heavy metal in soils was 0.82, the degree of pollution was alert level. The soil of Nansha Guangzhou City was of the slightly ecological hazard, Cu and Hg were primary ecological hazard factors.
