Abstract

Abstract

In order to study the surface soil of old town of Shenyang City,10 soil samples were collected in five major urban areas.The content of Zn, Cr, Ni, Pb, Cu, As and Cd in soil samples was determined by flame atomic absorption spectrometry and atomic fluorescence spectrometry,and their distribution characteristics were analyzed.The single factor pollution index method, potential ecological risk and human exposure risk assessment were used to analyze environmental risk and human exposure risk.The results showed that the average content of six heavy metals except As in old town was higher than that of Shenyang background values, among which the average content of Zn, Cd and Pb reached 3.45, 3.03 and 2.67 times of the background values; The single factor pollution index method result showed that As was in a clean state, but all the other elements had different levels of pollution, especially Zn and Cd reached heavy pollution level.The potential ecological risk result showed that Cd reached strong harm and other elements belong to slight level, and the total potential ecological risk index of the city, RI=44.28, belong to medium level of risk.Human exposure risk assessment result showed that children’s daily average exposure and non-carcinogenic risk were higher than that of adults, but the total non-carcinogenic risk of the studied heavy metals was less than 1, and the risk of carcinogenic heavy metals was also low.
