Abstract:

As the separation and purification methods of rare earth elements(REEs) were well developed,REEs have been widely used at present in many fields of industry and agriculture. The widespread application of REEs as the additives in fertilizers will inherently lead to their residues in environment, accumulation in organism,and entering into a food chain. The bioavailability and toxicity of REEs mainly depend on its dissolved species which can be partly assimilated by plants and animals,thus, the speciation of REEs in environment and organisms becomes more and more important today.
