Abstract
Lead and Cadmium are two types of heavy metals considered toxic for living organisms. Our researches focused on the speciation of Pb and Cd on soil which cultivated vegetables. In addition, organic matter content, pH and cation exchange capacity as a factor influencing heavy metal speciation and bioavailability for plants also analyzed. Heavy metals speciation carried out using a sequential extraction method then the Pb and Cd content on each fraction was analyzed by the atomic absorption spectrophotometer. The lead fraction in the soil is in the following order F3>F1>F5>F4>F2 whereas cadmium order F4> F1>F3>F5>F2. The organic matter, pH and cation exchange capacity on soil was 3.05%; 5.56 and 20.30 mek/100 g, respectively. The value of daily intake of metal (DIM) and health risk index (HRI)<1 indicates that the vegetables were relatively safe for consuming.
