Heavy metal contamination in soil-rice system and its spatial variation in southeastern China: a review

Food safety and the associated health risk is now one of the major concerns worldwide, especially in China. Rice is the dominant agricultural product in China and ranks second by quantity in the world. The quality of rice, thus, affects greatly human health. Among the factors influencing the food quality, soil contamination and the related quality are the main sources leading to the food contamination. It is very necessary to conduct some investigations on the contamination and relationship of heavy metals in the soil-rice system at a rice production region. The results will provide guidelines beneficial to soil quality improvement, scientific distribution of rice plant and food security in rice production areas.
