Abstract:

The heavy metal pollution of farmland soil directly affects agricultural products’ quality safety and threatens human health, so it is of great significance to carry out the classification management and risk control of farmland soil. By reviewing relevant policy papers and literatures at home and abroad, this study summarized current situation and characteristics of heavy metal pollution in farmland soil of China, analyzed the source of heavy metals in farmland soil, and systematically outlined the risk control measures of heavy metal pollution in farmland. Moreover, this study highlighted the latest research progress of soil remediation technologies such as agronomic regulation, soil improvement, bioremediation and so on. Finally, existing problems in risk control of heavy metal pollution in farmland soil were pointed out and future research directions were discussed.
