It is necessary to realize the current situation, harm, and management strategies of heavy metal pollution. On the basis of the situation of heavy metal pollution in the rice fields, the best methods which were match with rice fields can be chosen, including controlling heavy metal pollution sources, screening rice varieties of low absorption of heavy metal, using soil amendment, planting hyper-accumulator and growing transgenic plants. These methods were beneficial to improve yield and quality of rice, thus beneficial to human health. Now there were few rice varieties of low absorption of heavy metal, so greater efforts were needed in the future. Also, only if the select of hyper-accumulator change from repair single heavy metal pollution to compound, it could adapt to the complication of pollution places. What was more, there was a great space to develop transgenic plants. In a word, much attention should be paid to heavy metal pollution and control sewage water irrigation.
