Rapid modernization is proceeding and water pollution by detergents, agricultural chemicals, heavy metals and other toxic chemicals is now on problem with magnification of human activities in China. In this paper, the effect of cadmium on rice growth, bioaccumulation of cadmium to each part of rice, removal rate of cadmium from water and safety of food were investigated. Rice was grown from young plant to harvesting stage in vinyl house and exposed to cadmium for 80 days.The rice grew normally at the concentration range from 0.001 to 0.1mgCd·l-1, however, the growth of rice was extremely inhibited at the concentration of 100mg Cd·l-1. The Cd concentration of each part of rice was in the order of root>stem>leave>stalk>grain>brown rice. In the first 40 days of the treatment, the accumulation rate of each part of rice reached to 70-94% for the final accumulation at the harvesting time. It was found that the Cd concentration in water satisfying the safety standard is below 0.029mgCd·l-1, when Cd concentration in brown rice is 0.4mgCd·kg-1.
