Special Issue Information

Dear Colleagues,

The air pollutants (e.g., NOx, SO2, VOCs, PM2.5, dust, etc.) from the related sources could be transported following the wind patterns to the “receptor regions” and undergo photochemical and chemical processing to form other kinds of secondary species, such as O3, organic aerosols, PANs, and so on, during the transportation. The recent intense sandstorm over the north of China in early March and the regular mountain fire smoke covering North American during summer/fall represent two extreme examples of the influence of the transportation of air pollutants to local air quality. The local atmospheric pollutions could be caused by mixing of local emissions of primary or secondary air pollutants with regional or larger scale transported compounds.

Numerous studies have showed the contribution of the transported pollutants in some typical locations, such as Beijing, New York City, Paris, and so on; however, there is still a large research gap for other regions, which have not raised as much attention. At the same time, there are some unconventional pollutant emissions (such as VOCs emission from shale gas productions in US) and unusual extreme pollutant events influenced by the pollutant transportation (e.g., the above-mentioned sandstorm, mountain fire smoke, and biomass burning) have raised much attention, which could also provide some new insights to the regional scale air quality. Thus, we organized this Special Issue to better understanding local air pollutants sources and help local governments to establish relevant clean emission controls. The topics of this Special Issue include but are not limited to:

(1) The identification of air pollutants emissions from some unconventional sources or special extreme events;

(2) The identification of the tracers for the transported air pollutants;

(3) The atmospheric processing during transportation;

(4) The contributions of transported pollutants to local air quality;

(5) The emission control policies and their social effects (e.g., health, economic development, etc.).

Northern China was hit by a severe dust storm on 15 March 2021, covering a large area and bring devastating impact to a degree that was unprecedented in more than a decade. In the study, we carried out a day-and-night continuous monitoring to the path of the moving dust, using multi-spectral data from the Chinese FY-4A satellite combined with the Japanese Himawary-8 from visible to near-infrared, mid-infrared and far-infrared bands. We monitored the whole process of the dust weather from the occurrence, development, transportation and extinction. The HYSPLIT(Hybrid Single Particle Lagrangian Integrated Trajectory) backward tracking results showed the following two main sources of dust affecting Beijing during the north China dust storm: one is from western Mongolia; the other is from arid and semi-arid regions of northwest of China. Along with the dust storm, the upper air mass, mainly from Siberia, brought a significant decrease in temperature. The transport path of the dust shown by the HYSPLIT backward tracking is consistent with that revealed by the satellite monitoring. The dust weather, which originated in western Mongolia, developed into the “3.15 dust storm” in north China, lasting more than 40 h, with a transport distance of 3900 km, and caused severe decline in air quality in northern China, the Korean peninsula and other regions. It is the most severe dust weather in the past 20 years in east Asia. Full article

Chlorine (Cl) released from coal-fired power plants can be harmful to power equipment, the ecological environment and human health. Here, we investigated the Cl releasing characteristics from four coal-fired power plants (CFPPs) in China’s Anhui province based on an ion chromatography analysis of the combustion by-production samples collected from different locations of the power plants. The results showed that Cl content in coals was low (198–367 μg·g−1), which positively correlated with the contents of lead, mercury and total sulfur, but was weakly correlated with the moisture and ash yield in coal. The releasing rate of Cl during coal combustion was highly correlated with temperature and volatile matter, and most Cl is transferred into the flue gas. Dust collector and wet flue gas devices equipped in the CFPPs were robust for removing Cl in the particulate phase, and the fabric filter showed a higher removal efficiency than the electrostatic precipitator. This study can provide theoretical support for Cl pollution control in coal-fired power plants. Full article
