Abstract: Effect of heavy metal mixture pollution on rice growth is studied through pot experiment. Solutions for extracting available copper and cadmium are also explored. The results indicate that 2. 5% HAc can be used as available copper and cadmium extracting agent in acid paddy soil. Less than 5 mg/kg cadmium in soil will not have any effect on rice yield, however, cadmium concentration in the rice will exceed China National Adminissible Standard foi Food.
