Analysis on Heavy Metal Pollution State in Urban Surface Soil

With the accelerating process of urbanization, heavy metal pollution problem is getting worse. In order to find out the state of heavy metal pollution in urban surface soils, we divided the city into different functional areas, and conducted the surface soil sampling, heavy metals analysis, and urban heavy metal pollution of surface soil data gathering. On this basis, evaluate the state of heavy metal pollution using Nemerow index, and analyze the source of heavy metal pollution. Evaluation and analysis process is simple and reasonable, is conducive to engineering applications, and also for environmental management department of the scientific decisions.
