Research Progresses and Challenges of Mercury Biogeochemical Cycling in Global Vegetation Ecosystem
-
摘要: 汞是联合国环境规划署重点管控的全球性污染物.植被是联结大气圈与土壤圈的关键纽带，在全球汞生物地球化学循环中扮演着举足轻重的角色.植被生态系统是全球大气重要的汞汇，但由于大气‒植被‒土壤的汞界面交换过程及植物组织中汞的分布、来源与迁移转化规律及驱动机制认识不清，致使当前的全球汞生物地球化学循环模型缺失植被过程模块，无法厘定全球植被的大气汞汇通量.近年来迅速发展的汞同位素地球化学、同步辐射和微气象汞通量观测等新方法，为多层次解析不同类型植被与土壤及大气界面汞交换过程，阐明植物组织中汞的分布、来源与迁移规律提升了可能，能为进一步解决当前森林生态系统汞的生物地球化学循环的研究难点提供独辟蹊径的视角.Abstract: Mercury (Hg) is a global pollutant which has been listed by the United Nations Environment Programme focusing on control. Vegetation is a foundational link between atmosphere and pedosphere, and plays an important role in global Hg cycles. Currently, vegetation has been regarded as the important global sink of atmospheric Hg. However, the distinct knowledge gaps in Hg cycling among interface of air-vegetation-soil, and Hg distribution, sources, transformation and their biogeochemical mechanisms in vegetation components, lead to the current global Hg models with the poor parameterization schemes of vegetation related Hg processes. These largely restrain the comprehensive quantification of the vegetation sink for atmospheric Hg across the globe. Recently, the quickly developing Hg isotopic chemistry, HR-XANES/micro-XANES, and micro meteorological mercury flux observation technology provides a new insight in understanding the interface Hg biogeochemical processes among vegetation-soil-air surfaces, and assessing Hg sources and transformation and translocation in vegetations, specifically in forest ecosystems.
