英文摘要A labile rhizosphere soil solution fraction has been recommended to predict the bioavailability of heavy metals and rare earth elements to plants. This method used moist rhizosphere soil in combination with a mixture of 0.01 mol L-1 of low-molecular-weight organic acids (LMWOAs) as extractant. The extracted soil solutions were fractionated into two colloidal fractions of <0.45 mum (F-3) and <0.2 mum (F-2), and one truly dissolved fraction including free metal ions and inorganic and organic complexes (fractionr(0.2 mum,LMWOAs) approximate tor(0.45 mum,LMWOAs). In the case of rare earth elements the good correlation was obtained for both the wheat roots and shoots. Generally, the correlation coefficients obtained by LMWAOs were better than that obtained by the first step of BCR method. Therefore, LMWAOs and Firs, were strongly recommended to predict the bioavailability of metals in soil pools to plants.
