Research Progress on Influencing Factors of Migration and Transformation of Heavy Metalsat Water-sediment Interface

水-沉积物界面是重金属发生迁移转化的主要场所,环境中各种因素可对其过程产生影响,为探讨这些因素对重金属在水-沉积物界面迁移转化过程的影响,围绕沉积物周围的潜在因素进行全面分析,选择上覆水环境因子(pH值、氧化还原条件、离子强度和温度)、重金属赋存形态和沉积物颗粒大、小分别对重金属迁移转化的影响进行分析,探讨上述各因素对重金属迁移转化的影响机理机制过程,最后对重金属迁移转化方面的研究进行归纳总结和未来展望。

The water-sediment interface is the main place for the migration and transformation of heavy metals,and various factors in the environment will affect the process.In order to explore the influence of these factors on the migration and transformation process of heavy metals at the water-sediment interface,a comprehensive analysis was made around the potential factors around the sediment.The environmental factors of overlying water(pH,redox conditions,ionic strength and temperature),the occurrence form of heavy metals and the size of sediment particles were selected to analyze the influence on the migration and transformation of heavy metals,and the mechanism and process of the influence of these factors on the migration and transformation of heavy metals were discussed.Finally,the research on the migration and transformation of heavy metals was summarized and prospected in the future.
