These plant mechanisms are sufficient to desorb readily bioavailable polluting metals, such as Cd, which predominantly form easily hydrolysable, low-energy bonds to the soil solid phase [23]. To make plants take up Pb and other low bioavailable metals, which are much more strongly bound to the soil solid phase than Cd, strong synthetic chelating agents have been used to bring metals into the soil solution. For example, the addition of Na salt of ethylenediamine-tetracetic acid (EDTA) to soil shifted Pb mostly from the carbonate fraction to the fraction soluble in the soil solution, in which the Pb concentration increased from 3 to 362 mg kg-1 (Figure 3).
