Aquatic Sciences and Biogeochemistry

溶解有机物（DOM）调节水生态系统中金属的运输和生物利用度，尽管其突出的环境作用，其特性和对金属的反应性仍然是有争议的问题。一个多元的方法DOM的生态地球化学特征将开发和应用于DOM从各种水生生态系统，包括陆地和海洋北极系统。通过连接实验室实验和现场观察，这一创新的研究计划将产生对金属的命运和流动性以及环境约束对污染物途径的影响的全面了解。该研究项目的结果将为风险评估人员提供一个更可靠的工具，用于预测人为影响和环境变化。

Dissolved organic matter (DOM) regulates the transport and bioavailability of metals in aquatic ecosystems and, despite its prominent environmental role, its characterisation and reactivity toward metals are still matters of debate. A multivariate approach for the biogeochemical characterization of DOM will be developed and applied to DOM from various aquatic ecosystems including terrestrial and marine arctic systems. By bridging laboratory experiments and in situ observations, this innovative research program will yield a comprehensive understanding of the fate and mobility of metals and of the impact of environmental constraints on pollutant pathways. The results of this research program will provide a more reliable tool to risks assessors for the prediction of both anthropogenic impact and environmental change.
