Abstract :
Heavy metals are elements with high atomic weight, and large amounts of these metals may be harmful to living organisms. Mercury is one of these metals and can cause various problems for human health. The aim of this study was to investigate the bioavailability of mercury by Afraplet species. With the permission of Natural Resources seedlings a year of Maple of nursery was prepared and the solution Chloride Mercury with concentrations of 20, 40 and 60 mg per liter of prepared solution is then added to the soil, and the seedlings of maple in the pot after the period of six months from growth of seedlings, leaves, stems and roots of the seedlings were sampled. Using ANOVA and Duncan test were examined.The highest level of Mercury accumulation in aerial organs in leaves, stems and roots and, respectively, 55; 40; 45.67; mg/kg. Based on the results of this research maple species suitable for remediation of soils contaminated with metal is mercury.
