| Abstract: | The paper has investigated and evaluated the contents of heavy metals in the soil of Nanchong City. The result shows the most soils of Nanchong City are polluted to a different degree. Refering to average integrated index of factors,the index is over 2,being grave pollution. The main pollution factors of heavy metals in soil are Cd and Cu,the average respective factors of Cd and Cu are 2.75 and 1.01. The pollution degree of different places is very different, mainly decided by factories or hospitals there. |
