Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.

In this study, we report a change of morphological distribution for PM2.5 air pollution in Ulaanbaatar. Comparing the measurement results in 2011 and 2017 the concentration of particle size 0.8μm was decreased from 92% to 76.7%. Among winter samples in 2011 it is identified 0.4-0.8μm sized particles covering 48.8% of total, and for samples in 2017 it is 61.7%. This shows that 0.4-0.8 microns of particulate matter predominate in the air pollution caused by solid fuel combustion. The 66.8% of the particles identified <0.8μm sized are in summer samples in 2011. This percentage has increased up to 94.5% in the samples in 2017. It is having been to the most harmful fraction of particulate matters for human health. About particulate shapes distribution, irregular shapes dominated in winter in 2011 and sphere shapes dominated in summer samples. While irregular shapes dominated in the samples in 2017, it was independent of season. This provides on origin of pollution, for example, the summer PM2.5 pollution is sphere shape from the soil in summer and winter PM2.5 pollution is irregular from the solid fuel combustion. This is a pilot compared study of PM2.5 particles in air pollution of Ulaanbaatar.

AbstractCold-season air quality in Seoul, South Korea, has been improved noticeably between 2001 and 2015 with a near-50% decrease in the mean concentration of particulate matter with aerodynamic diameters ≤10 μm (PM10). Like the change in mean concentration, the occurrence frequency and intensity of the extreme-high-PM10 episodes exceeding 100 μg m−3 has significantly decreased as well. In addition to the multilateral efforts of the South Korean government to reduce air pollutant emissions, this study proposes that large-scale circulation changes also could have contributed to the air quality improvements. Specifically, the recent weakening of the Aleutian low may have intensified the tropospheric westerlies around the Korean Peninsula, resulting in a shorter residence time of particulate matter over South Korea. Thus, despite constant governmental effort to reduce pollutant emissions, the improvement in air quality over South Korea may be delayed if the Aleutian low recovers its past strength in the future. This study emphasizes the importance of the meteorological field in determining the air quality over South Korea.
