中文摘要: |
砷及重金属元素从环境进入土壤后,其可浸提性、可交换性、生物有效性或毒性均会随时间的延长而缓慢变化,即发生所谓的"老化"。本文对外源砷进入土壤后老化的过程、影响因素、机理等进行了较系统探讨,可为相关研究提供参考。 |
英文摘要: |
After the arsenic and heavy metal elements enter into the soil from the environment, the extractability, exchangeability, bioavailability or toxicity of them will slowly decrease with time, which is described as aging process. In this paper, the process of exogenous arsenic aging in soil, the influences of soil properties on aging process and associated aging mechanisms are systematic discussed, which will provide reference for the related study. |
