Abstract
Through leaching experiments and simulated rainfall experiments characteristics of vertical leaching of exogenous rare earth elements REEs and phosphorus P and their losses with surface runoff during simulated rainfall in different types of soils terra nera soil cinnamon soil red soil loess soil and purple soil were investigatedResults of the leaching experiments showed that vertical transports of REEs and P were relatively low with transport depths less than 6 cm The vertical leaching rates of REEs and P in the different soils followed the order of purple soil terra nera soil red soil cinnamon soil loess soil Results of the simulated rainfall experiments 83 mm h−1 revealed that more than 92 of REEs and P transported with soil particles in runoffIn this study the laboratory simulated rainfall experiments were conducted at Fangshan Experimental Center of Beijing Normal University The authors thank Professor Liu Baoyuan and Mr Gao Xiaofei of Beijing Normal University for their help in the experiments
