This experiment was carried out to investigate the concentration level of heavy metals on soil, brown rice and cooked rice in the basic research of food contamination caused by heavy metal in irrigation water. The suitable range of pH to extract the Cadmium, Copper, Lead and Zinc was from 5 to 10. The effect of diverse ions on determination did not showed. The contents of heavy metals in irrigation water were Cadmium 28.68ppb. copper 1,693.27ppb, Lead 298.45ppb, Zinc 1,946.15ppb and Arsenic 128.17ppb, respectively.
After cultivation of paddy rice with polluted water, the contents of heavy metals on soil, brown rice and cooked rice were raised, but did not serious degree.
