摘要

这篇综述的重点是地中海边缘海亚得里亚海的汞物种形成,由于人为汞负荷,亚得里亚海代表了其独特的生物地球化学亚单位。通过概述该领域的研究现状,介绍了亚得里亚海汞循环的最新知识:海水和沉积物中汞物种的时空分布和发生,以及化学转化。我们总结了汞物种形成的研究结果,以描述其在亚得里亚海的存在和命运。亚得里亚海是地中海的汞净来源,因为在北亚得里亚海观测到的汞总浓度最高,在南亚得里亚海坑观测到的甲基汞浓度最高。然而,汞的生物地球化学循环尚不完全清楚,我们对汞在隔间之间的迁移及其(生物)转化的理解也很有限。未来的研究需要侧重于汞转化的微生物和化学过程,以提高我们对亚得里亚海汞污染对环境和人类健康影响的理解。

The abundance, distribution and speciation of mercury in waters and sediments of the Adriatic Sea: a review
This review focuses on mercury speciation in the Adriatic Sea, a marginal sea of the Mediterranean, which represents its distinct biogeochemical subunit due to anthropogenic mercury loadings. The current knowledge about mercury cycling in the Adriatic is presented through an overview of the state of the art of research in this area: temporal and spatial distributions and occurrence of mercury species in seawater and sediment, and chemical transformations. We summarised research results of mercury speciation in order to describe its presence and fate in the Adriatic Sea. The Adriatic Sea represents a net source of mercury to the Mediterranean Sea due to the highest total mercury concentrations observed in the North Adriatic Sea and the highest methylmercury concentrations in the South Adriatic Pit. However, the biogeochemical cycle of mercury is not completely known and our understanding of mercury transport between compartments and its (bio)transformations is limited. Future research needs to focus on microbial and chemical processes of mercury transformations to improve our understanding of the impacts of mercury contamination on the environment and human health in the Adriatic Sea.
