Special Issue Information

Dear Colleagues,

Mercury (Hg) is a pollutant of much concern due to its global distribution and toxicity to living organisms. Fluvial ecosystems are crucial sites to investigate Hg biogeochemistry due to the pivotal role of floodplains for human activities. Globally, many fluvial ecosystems are severely impacted by Hg, derived from multiple sources such as coal combustion, smelting of metal ores, Hg/Au mining, and soda/PVC plants. On the other hand, Hg atmospheric distribution around the globe can affect pristine fluvial networks without local emission sources. Once they enter rivers, Hg hotspots are rapidly diluted and transported hundreds of kilometers from the original source, and finally redistributed in all sediment of the river corridors ruled out by river hydrodynamics. Sediments then become new nonpoint sources of Hg in rivers, and Hg recycling may last for hundreds of years, leading to great variability in spatial patterns, and difficult management strategies. Additionally, Hg methylation may occur in anoxic sediments, favoring the uptake by local biota.

This Special Issue invites critical reviews, research papers, and communications bringing together knowledge on the behavior of Hg in fluvial environments, including implications for human health, management of contaminated sediment, and future research needs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Environments is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
