| 1 | 三峡库区消落带土壤溶解性有机质溯源:基于氮/碳比值的线性双端元源负荷分析显示文摘土壤溶解性有机质(soil DOM)作为陆地系统天然有机质的重要组成部分,以其活跃的生物地球化学性质,在污染物的环境行为中扮演着极其重要的作用.而了解其来源和结构组成是进一步明确其'结构-反应活性'的关键和前提.本文以三峡库区消落带土壤DOM为研究对象,基于传统氮/碳比值(N/C)及衍生的双端元源负荷模型,讨论该溯源方法在分子水平上的合理性;同时采用光漂白试验,进一步讨论各样本反应活性与其源负荷的相关性.结果表明,N/C值和双端元线性混合模型值均表明土壤DOM具有'陆源'和'内源'的双重特性——这与其他高级分析技术溯源结果基本一致.这种传统溯源分析结果在分子水平上具有合理性,但仅仅反映DOM结构和来源在特定面相上的信息,只能证明库区土壤DOM属于'混合型来源',却无法提供分辨率更高的特定组分来源信息.另外,N/C元素比值及源负荷分别和光漂白动力学过程极显著相关,因此可作为较方便的指标,快速简单判断DOM的光化学反应活性.但在关注DOM本身生物地球化学的研究工作中,仍建议使用多重方法的比较分析,以便于提高单一解析方法的分辨率. | 江韬 Joeri Kaal 梁俭 刘江 张耀玲 王定勇 魏世强 赵铮 | 2019 | 环境科学2019，40，6： | 5 |
| 2 | Linking the electron donation capacity to the molecular composition of soil dissolved organic matter from the Three Gorges Reservoir areas,China显示文摘Soil dissolved organic matter(DOM)plays an essential role in the Three Gorges Reservoir(TGR)as a linkage between terrestrial and aquatic systems.In particular,the reducing capacities of soil DOM influence the geochemistry of contaminants such as mercury(Hg).However,few studies have investigated the molecular information of soil DOM and its relationship with relevant geochemic al reactivities,including redox properties.We collected samples from eight sites in the TGR areas and studied the link between the molecular characteristics of DOM and their electron donation capacities(EDCs)toward Hg(II).The average kinetic rate and EDC of soil DOM in TGR areas were(0.004±0.001)hr-1 and(2.88±1.39)nmol e-/mg DOMbulk,respectively.Results suggest that higher EDCs and relatively rapid kinetics were related to the greater electron donating components of ligninderived and perhaps pyrogenic DOM,which are the aromatic constituents that influenced the reducing capacities of DOM in the present study.Molecular details revealed that even the typical autochthonous markers are important for the EDCs of DOM as well,in contrast to what is generally assumed.More studies identifying specific DOM molecular components involved in the abiotic reduction of Hg(II)are required to further understand the relations between DOM sources and their redox roles in the environmental fate of contaminants. | Tao Jiang Joeri Kaal Jiang Liu Jian Liang Yaoling Zhang Dingyong Wang | 2020 | Journal of Environmental Sciences2020，32，4： | 2 |
