title: Effects of heavy metal terbium on contents of cytosolic nutrient elements in horseradish cell.
abstract: The wide application of rare earth elements (REEs) has led to the accumulation of REEs in soil and plant. Thereby, the effect of Tb(3+) on the contents of cytosolic nutrient elements in horseradish was investigated with the synchronous detection technique of scanning electron microscope and energy dispersive X-ray spectrometry. It was found for the first time that the foliar spraying treatment of Tb(3+) destroyed the structure of horseradish mesophyll cells, and then changed the contents of the cytosolic nutrient elements in horseradish, especially Ca. The effect of Tb(3+) was increased with increasing the concentration of Tb(3+). The hydroponical treatment of Tb(3+) could not obviously change the structure of protoplast and the contents of the cytosolic nutrient elements in horseradish leaves. The results indicated that the accumulation of Tb(3+) in soil and plant leaves displayed the different toxic effect on plant leaves.
