Special Issue Information

Dear Colleagues,

The process of land-air exchange is the bridge of material and energy exchange between the biosphere and atmosphere. Various substances between the land and the atmosphere are closely linked through the land–air exchange process. However, the exchange mechanism of active chemical components between the land and the atmosphere needs more detailed consideration, in particular, its emission, transport and sedimentation process. At the same time, there are still considerable uncertainties in the measurement and simulation of material and energy transport from the soil to the vegetation canopy to the atmospheric boundary layer. With global climate change and human activities, the land use state of the Earth's surface and the occurrence form of atmospheric components have undergone profound and complex changes. Whether these changes have caused changes in the land–air exchange mechanism, what impact they have on the Earth's environment and how to describe these changes and impacts more accurately through the improvement of observation technology and the optimization of numerical models require further scientific discussion. In this regard, we hope to discuss the current frontier issues in this Special Issue. We encourage research on new discoveries, new insights and new viewpoints related to the land-air exchange process, including, but not limited to, the following topics:

  • Observation and simulation of the land-air exchange process on different underlying surfaces;
  • Relationship between emissions, transport and the deposition of atmospheric components;
  • Interaction between air pollution change and terrestrial ecosystem;
  • Land-air interaction of new air pollutants such as antibiotics, etc.

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Studying atmospheric mercury (Hg) deposition in a forest system is a key step to understanding Hg biogeochemical cycles. However, observations based on Hg deposition fluxes in worldwide stations under forest ecosystems tend to differ considerably. In this work, a sampling station was set up in Dinghu Mountain to study the atmospheric Hg’s dry and wet deposition in typical forest ecosystems in Southeast China. One hundred and two atmospheric dry and wet deposition samples were collected with an automatic sampler from March 2009 to February 2010, and concentrations of Hg, magnesium (Mg), calcium (Ca), cadmium (Cd), copper (Cu), zinc (Zn), lead (Pb), and chromium (Cr) were detected. The results showed that the annual rainfall weighted average Hg concentration was 56.8 ng L−1, and 79.8 ng L−1 in the dry deposition. The mean total deposition flux was 158.8 μg m−2, and the wet deposition was predominant. The highest and lowest concentrations were detected in the high-temperature rainy season. Generally, the wet deposition flux was notably positively correlated with the rainfall. The source of atmospheric Hg deposition in Dinghu Mountain was analyzed using principal component analysis (PCA). The main source of Hg in precipitation was soil dust, followed by coal and fuel (automobile exhaust). The primary source of Hg in dry deposition was fuel (automobile exhaust), followed by soil dust, which indicates that Dinghu Mountain has been polluted by the anthropogenic sources of Hg.
