Therefore, the objectives of this study are to add the different levels of copper and zinc, total 6 treatments of different levels of copper and zinc in soil, into 3 different Taiwan rural soils to understand the bioavailability of copper (Cu) and zinc (Zn) in the contaminated soils and also to understand the Cu and Zn uptake in the brown rice. The treated soils are incubated for one month for rice production in pot experiments. We can provide more information to make the evaluation on the food safety and rice productivity of brown rice growing on the Cu- or Zn-contaminated soils in Taiwan.重金屬土壤管理技術作物安全性土壤污染銅鋅Heavy metalssoil management techniquesfood safety土壤污染soil pollution銅copper鋅Zincfood safetysoil pollutionCopperZinc
