Corn can repair heavy metal contaminated soil

Can corn be used to repair soil contaminated with heavy metals?


Correct! On the 27th, a repair technology was demonstrated at a vegetable base in Baiyun District, Guangzhou, and the restoration effect was good.


Due to the pollution of waste water, waste gas, solid waste and the application of chemical fertilizers, pesticides and sludge, heavy metals have formed a certain accumulation in the agricultural soil of the urban suburbs of the Pearl River Delta. The content of heavy metals in the soil is generally high, and soil pollution has become The bottleneck restricting the healthy and sustainable development of modern agriculture.


The project “Study on the Environmental Chemical Behavior and Remediation Mechanism of Pollutants in Soils”, completed by South China University of Technology and other units, has carried out the release, migration and conversion of heavy metals and pollutants around the poisonous heavy metals and organic pollutants in the soil. Study on the environmental chemical behavior and repair mechanism of the removal process, the corn can repair the soil contaminated by heavy metals and organic pollutants, and develop a “production-side repair” of the heavy metal-organic compound contaminated soil using economic crop corn. Repair technology.
