ABSTRACT To study soils and plants pollution with heavy metals and remediation techniques, five pot experiments were carried out. A surface clay soil sample was collected (0 – 20 cm) and prepared for experiments. Ni, Cd, Cu and Zn metals were chosen for this study. The first experiment was conducted on the chosen metals (in carbonate form) with different concentrations for each metal. Whereas, the experiments from 2 to 5 were conducted in sulphate form (0.5% Ni, 0.25% Cd, 1% Cu and 1% Zn of soil weight). The conducted experiments were carried out in two replicates for each treatment. Chemical amendments (CaCO3, CaHPO4 and CaSO4.2H2O) were added in 0, 2, 4 and 6% for each metal in experiments 2, 3 and 5, respectively. Whereas, NH4H2PO4 amendment was added in 0, 1 and 2% in experiment 4. The metals and amendments were mixed well with soil pots. All treatments were planted with barley and fenugreek then irrigated with nutrient solution (experiments 1, 2, 3 and 5) and distilled water (experiment 4). After 35 days, all plants were totally collected, washed well, dried, weighted and prepared for metal determination. This process was repeated three times. The obtained results showed that metals uptake by barley and fenugreek increased as the metal in the soil increased. Addition of chemical amendments to polluted soil differ in their effects on reducing uptake of Ni, Cd, Cu and Zn metals by cultivated plants, depending on soil pH, type of metal, type of amendment, rate of amendment, plant species and characteristics. Generally, the used amendments in this study reduced DTPA-extractable and uptake (except in some cases) of Ni, Cd, Cu and Zn by cultivated plants in polluted soils. More studies are needed to answer and solve the problems of soils and plants pollution with heavy metals.
