Abstract: In order to ascertain the heavy metal content of organs of rice plants, distribution and accumulation of Cd, Cr, Pb in rice were studied after exogenous soluble heavy metals put in the paddy soil in 2013. The results showed that with the increase of heavy metal, heavy metal enrichment of rice plants rose, but at high concentrations of heavy metal pollution, enrichment factor decreased in rice plants. And there was no significant difference between the height of rice plant and dry matter. It was demonstrated that the migration capacity of heavy metals in rice plant in the order was: Cd>Cr>Pb, heavy metals in different organs of rice plant showed enrichment capability root>stem>leaf>grain. And the content of heavy metals of aleurone layer in rice grain was significantly greater than that in endosperm. After processing into milled rice, Cd content of brown rice can be reduced by 19%, Cr content can be reduced by 56.8%, Pb content can be reduced by 29.8%. Therefore, processing can reduce the risk of heavy metal pollution of rice and avoid certain eating risk.
