Abstract:The NAS four-step and potential ecological risk index were used to evaluate the Xishan brownfield environment risk which included the health risk and ecology risk. The health risk was against the nearby residents (both the adults and children), while the ecology risk was against the surrounding environment. The results show that the adult and child carcinogenic risk was 7.06′10-8 and 1.16.′10-7, respectively, and the adult and child non-carcinogenic risk was 1.12′10-1and 5.76.′10-2, respectively . The heavy metals Pb and Cr produced more non-carcinogenic risk. The ecology risk was in moderate hazard in Xishan District. The ecology risk caused by the heavy metal Cd was the most serious. Among the four urban development module in Xishan District, the environment risk in the Tin East Metro was the maximum, followed by Anzhen-Yangjian and Donggang-Xibei new towns , and the Swan Lake new towns was the least.
