Abstract

The serious issue on heavy metal pollution in farmland of China has posed a potential threat to food security. On the basis of the current status of heavy metal pollution in farmland soils and grain in China, three categories of forbidden area, limited-yield area, and suitable yield area for agricultural producing areas should be emphasized. The application of crop varieties with low accumulation of heavy metals and passivation-barrier technology together with agricultural management could achieve the safe utilization of farmland with light-moderate heavy metal pollution. And this could definitely provide technical support for the safety of grain production of China and even the world. Furthermore, some key points and suggested strategies have also been proposed towards the safe utilization of farmland in China.
