摘要：In order to evaluate potential risks of farmland soil heavy metals to the Xinxiang city, more than 50 samples were practically collected and analysed. Results show that Cd, Ni and Zn are in higher degree of enrichment with reference of national quality standard for soil environment (GB15618-1995). Ranking order based on index of geo-accumulation assessment is Cd > Ni > Cu > Zn > Cr. Results of coefficients of potential ecological risk index show risk ranking order is Cd > Ni > Cu > Zn > Cr, and Cd is in class of extremely potential ecological risk. Result of integrated Hakanson potential ecological risk assessment show this farmland soil of the Xinxiang city is under very high potential ecological risk. Result of risk assessment code indicates Cd makes a very high risk to human health and stability of ecosystem not only because of its very high enrichment but also its high bioavailability. ? 2013 Springer-Verlag.
