The aim of the study was to assess the influence of the soil pH, from ploughed soil layer from the Ialomita region, on the mobility of heavy metals (Cadmium, Copper, Manganese and Zinc), estimated by heavy metals extractable contents in DTPA-TEA-CaCl2. Because heavy metals exist in soil in different solid-phase forms that vary in terms of availability, total content of metals in soil are poor indicators of toxicity. In order to assess a risk of heavy metal pollution in soil should consider both mobile and availabi...
