外源REE对生态环境影响研究
- Title:
- Studies of the Effect on Extra-REE for Bio-environment
- Keywords:
- REE; environment effect; study
- 摘要:
- 通过示踪区植物对稀土元素的吸收和分布研究，以及对利用稀土元素示踪法研究土壤侵蚀的野外径流小区径流地中清水样品的稀土元素含量分析，证明示踪REE的生物地球化学行为较为稳定，不易被植物吸收，也不会因水迁移而影响地下水和地表水的水质。
- Abstract:
- The REE distributions in the plants grown in tracing area and the REE contents in the water collected from field plot runoff pool built up for studying soil erosion by using REE tracer method have been determined in this study. Experimental results show that because the geochemical activity of REE marked in soil is of comparative stable and is difficultly absorbed by plants,it does not effect the quality of both underground water and surface water.
