摘要

摘要: 黑碳(black carbons,BCs)是化石和生物质不完全燃烧形成的碳质连续体,广泛分布于土壤和沉积物中,对生源要素及污染物的迁移转化具有重要作用。新鲜BCs进入环境后会在生物或非生物的作用下发生理化性质的改变,即老化。研究该过程中BCs的变化规律及机理,对于预测其环境行为及生态效应非常重要。概括了氧气、水分、温度、pH等影响老化的环境因素,总结了国内外BCs老化研究的方法,分析了实验室各种老化模拟方法对BCs理化性质的影响,探讨了其机理,对比了人为老化和自然老化之间的差异。指出当前BCs老化研究存在的问题主要是自然老化数据欠缺,仍缺乏定量的、系统的研究,以及老化研究方法有待革新等。

Abstract: Black carbons (BCs) are carbon continua formed by incomplete combustion of fossil and biomass. They are widely distributed in soils and sediments and play important roles in migration and transformation of biogenic elements or pollutants. After entering the environment, the physical and chemical properties of fresh BCs will be changed by biotic or abiotic action, which is called aging. Investigating the change rule and mechanisms of aging processes of BCs are very important for predicting their environmental behaviors and ecological effects. Aging-related environmental factors such as oxygen, moisture, temperature, and pH were discussed. The domestic and foreign research methods of BCs aging were summarized, and the effects of various aging simulation methods on the physical and chemical properties of BCs were analyzed. Then, the mechanisms of BCs aging and the differences between artificial and natural aging were further discussed. The main problems in current aging research were summarized, including the lack of natural aging data, the lack of quantitative and systematic research, and the aging research methods needing to be innovated, etc.
