| Abstract: | Field investigation with two years were carried on.The results obtained were shown:(1) The content of Cu,Zn,Pb,Cd,As in soils was significantly negatively correlated with the dis- tance to the soures of pollution.(2) The content of Cu,Zn,Pb,Cd in all parts of rice plant was highly positive correlated with the content of total Cu,Zn,Pb,Cd and soluble Cu,Zn,Pb,Cd (DTPA).More than 80% of Cu,Zn,Pb,Cd uptaked by rice plant accumulated in stem and leaf.(3) The results of regression was shown that the content of heavy metal in brown rice was affected not only by total content and soluble Cu,Zn,Pb,Cd of soils,but also by pH,OM and CEC of soils. |
