Distribution and Ecological Risk Assessment of Heavy Metal Elements in Soil

Abstract:

Article Preview

In order to assess the risk of heavy metal elements, including mercury, cadmium, lead, chromium, copper and zinc in soil, the soil was tested by Nemerow and Hakanson methods to assess the pollution and potentially ecological risk. The results indicated that among six kinds of heavy mental elements, cadmium had the highest accumulation, lead and chromium had the lowest accumulation in urban topsoil by comparison to the background concentration of the second grade standard values of the Chinese environmental quality standards for soil. The pollution degree of heavy metals used by Nemerow methods was showed medium pollution in one-third sample sites and the others were slight. The potentially ecological risk was slight. The degree of heavy metal pollution and the potentially ecological risk were slight using the two methods.
