Special Issue Information
Dear Colleagues,
This Special Issue on “Atmospheric Mercury Dynamics in Remote Regions” is open to all aspects of atmospheric mercury science including, but not limited to, sources, transport, transformation, and atmosphere–surface exchange, with particular emphasis on remote regions. The rationale for this Special Issue is to understand mercury dynamics at baseline sites, i.e., in the absence of significant local/regional anthropogenic pressure, and to evaluate/predict variability in the context of global change.
Mercury has long been regarded as a global atmospheric pollutant, which can bioaccumulate to elevated levels in humans and wildlife upon exposure. The UNEP Minamata Convention on Mercury entered into force in 2017 and commits its 127 parties to curb anthropogenic emissions. Understanding the response of mercury dynamics to anthropogenic and natural perturbations (e.g., climate, land-use, atmospheric composition changes) is key to assessing the effectiveness of the Minamata Convention. Current and future climate change may for instance counterbalance international efforts to reduce mercury emissions by remobilizing legacy reservoirs. There is an urgent need to better understand and predict mercury dynamics in relatively pristine environments, where impacts of global environmental changes can be quantitatively assessed.
We are particularly open to process-based knowledge on atmospheric mercury in remote regions, including polar, open ocean, forest, or any locations surrounded by little point source emissions, which are representative of typical regional baseline atmospheric conditions and composition. The historical, present-day, and future evaluations of any changes regarded as global change such as climate change, land-use change, and changes in atmospheric composition, anthropogenic activities, and legacy emissions on atmospheric mercury are also welcome. The technical approach (concentration and isotope measurements, numerical modeling, trend analyses) to addressing these themes is unlimited.

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 submissions that pass pre-check are 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. Atmosphere 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 2400 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.
