Special Issue Information

Dear Colleagues,

Rising temperatures and changing climate have various implications on all the spheres of the earth’s system. One of the most important and complex elements of climate change is dust pollution. It plays a pivotal role in global ecological processes and biogeochemical cycles. Dust, once considered to be a natural emission of particles into the atmosphere, is directly and indirectly influenced by anthropogenic activities to a large extent in the current scenario. Humans influence dust emissions directly by escalating land use through deforestation and increased construction activities, among others, and indirectly by contributing to atmospheric warming, which results in desertification. Complex dynamics, processes, and interactions of dust with the environment, ecosystems, and humans require thorough study in the context of climate change and human interference. The complexity of dust stems from the varied mixtures of compounds it contains. Robust measurement approaches therefore underpin our ability to develop a holistic picture of atmospheric dust pollution. This will enable scientists and engineers to design controls and develop blueprints for various systems to adapt and deal with the increasing dust pollution levels.

The main aim of this Special Issue is to integrate and summarize the contemporary insights and findings from dust pollution research. We invite submissions of original research articles and reviews on dust pollution including but not limited to:

  • Source forensics of dust;
  • Physical, chemical, and biological characterization of dust aerosols;
  • Fate and transport of dust at both regional and global scales;
  • Interaction of dust with biogeochemical and hydrological cycles;
  • Influence of dust pollution on air microbiome;
  • Human health and environmental impacts of atmospheric dust;
  • Consequences and influence of climate change on the synergistic exchanges between atmospheric dust and land-ocean ecosystems;
  • Control strategies and designs to lessen the effects of dust pollution.

A new method, namely, force–distance curve mapping, was developed to directly measure the adhesion force of individual aerosol particles by atomic force microscopy. The proposed method collects adhesion force from multiple points on a single particle. It also takes into account the spatial distribution of the adhesion force affected by topography (e.g., the variation in the tip angle relative to the surface, as well as the force imposed upon contact), thereby enabling the direct and quantitative measurement of the adhesion force representing each particle. The topographic effect was first evaluated by measuring Polystyrene latex (PSL) standard particles, and the optimized method was then applied on atmospherically relevant model dust particles (quartz, ATD, and CJ-1) and inorganic particles (ammonium sulfate and artificial sea salt) to inter-compare the adhesion forces among different aerosol types. The method was further applied on the actual ambient aerosol particles collected on the western coast of Japan, when the region was under the influence of Asian dust plume. The ambient particles were classified into sea salt (SS), silicate dust, and Ca-rich dust particles based on individual particle analysis (micro-Raman or Scanning Electron Microscope/Energy Dispersive X-ray Spectroscopy (SEM-EDX)). Comparable adhesion forces were obtained from the model and ambient particles for both SS and silicate dust. Although dust particles tended to show smaller adhesion forces, the adhesion force of Ca-rich dust particles was larger than the majority of silicate dust particles and was comparable with the inorganic salt particles. These results highlight that the original chemical composition, as well as the aging process in the atmosphere, can create significant variation in the adhesion force among individual particles. This study demonstrates that force–distance curve mapping can be used as a new tool to quantitatively characterize the physical properties of aerosol particles on an individual basis. Full article

In recent years, hazy weather (hazy weather (HW) has frequently invaded peoples’ lives in China, resulting in the disturbance of social operation, so it is urgent to resolve the haze pollution (HP) problem. A comprehensive understanding of HP is essential to further effectively alleviate or even eliminate it. In this study, HP characteristics in China, after 2013, were presented. It was found that the situation of HP is getting better year by year while it has been a pattern of high levels in the north and low levels in the south. In most regions of China, the contribution of a secondary source for HP is relatively large, and that of traffic is greater in the regions with rapid economic development. Hazards of HP were then summarized. Not only does HP cause harm to human health, but it also has effects on human production and quality of life, furthermore, property and atmospheric environment cannot be ignored. Next, the source and non-source control technologies of HP were first reviewed to recognize the weakness of HP control in China. This review provides more systematic information about HP problems and the future development directions of HP research were proposed to further effectively control HP in China. Full article
