    Abstract Atmospheric pollution can affect human production life and physical and mental health to a great extent. In this paper, the hourly pollutant monitoring data from five state-controlled automatic atmospheric monitoring stations in Daqing City from 2017 to 2021 are collected to analyze the temporal and spatial variation patterns of CO, SO2, NO2, PM2.5, PM10, O3. And to assess the health risks of atmospheric particulate matter. The HYSPLIT model is applied to analyze air pollutants' transport pathways and the potential source areas of atmospheric particulate matter with the PSCF model. The results show that the concentrations of SO2 and NO2 are higher in the north of Daqing and the concentrations of pollutants generally show a decreasing trend with time. The hazard quotient (HQ) for atmospheric particulate matter, which is slightly above the safe range set by the EPA, is higher in winter and spring. After principal component analysis, CO, NO2, and PM10 are the main factors affecting PM2.5. In the summer, the main urban area's air pollution is mostly influenced by the southwest pollution trajectory. In other seasons, the northwest route predominantly regulates the regional transfer of contaminants. The key regions that could be the sources of atmospheric particulate matter include North China, Inner Mongolia, Mongolia, and Russia.

    Abstract With cotton production in Xinjiang increasing annually, the impact on the environment of agricultural waste produced to improve production has been reflected. This study selected Bozhou of Xinjiang, the main cotton producing region in northern Xinjiang, as the research object, and collected hourly concentration data of six pollutants from 2017 to 2021, and analyzed the spatial and temporal distribution characteristics of each pollutant. At the same time, Morlet wavelet analysis was used to further analyze the variation period of PM

    Abstract In recent years, with the continuous advancement of China's urbanization process, regional atmospheric environmental problems have become increasingly prominent. We selected 12 cities as study areas to explore the spatial and temporal distribution characteristics of atmospheric particulate matter in the region, and analyzed the impact of socioeconomic and natural factors on local particulate matter levels. In terms of time variation, the particulate matter in the study area showed an annual change trend of first rising and then falling, a monthly change trend of "U" shape, and an hourly change trend of double-peak and double-valley distribution. Spatially, the concentration of particulate matter in the central and southern cities of the study area is higher, while the pollution in the western region is lighter. In terms of social economy, PM

    Abstract During the “13th Five Year Plan” period, the nationwide mean concentration of PM₂.₅ in 2020 decreased by 28.8% compared to that in 2015. Exploring the relative impact of anthropogenic emission control and meteorological conditions to the reduction in PM₂.₅ concentration is a key step in further ensuring the accuracy of plans for the control of atmospheric environmental problems. In this study, the KZ filter and WRF-CMAQ model were used to quantitatively evaluate the relative impact of anthropogenic emission control and meteorological conditions to the decline in PM₂.₅ concentration. The KZ filter results show that the changes in PM₂.₅ concentration in Changchun were mainly caused by the short-term (45.95%–54.74%) and seasonal (31.62%–42.65%) fluctuations of pollution precursor emissions and meteorological conditions, and the average decline rate for the PM₂.₅ concentration after meteorological adjustment (3.36) is lower than that of the original data (3.74). Based on the KZ filter results, the relative impact proportions of meteorological conditions and anthropogenic emission control to the decline in PM₂.₅ concentration in Changchun are 11.36% and 88.64%, respectively, while the numerical simulation results of the WRF-CMAQ model show values of 14.79% and 85.21%, respectively. The results of both methods indicate that, although both meteorological conditions and anthropogenic emission control are conducive to the improvement of the atmospheric environment, anthropogenic emission control played a major role in the decline in PM₂.₅ in Changchun from 2015 to 2020, and the impact of meteorological conditions is relatively limited.

    Abstract Land use and land cover (LULC) changes have a considerable influence on the surface energy balance, altering regional meteorology and air quality. However, this impact is not quantified in Changchun, an important city in the old industrial base of Northeast China. In this study, based on the Weather Research and Forecasting-Community Multiscale Air Quality (WRF-CMAQ) model, the LULC2017 (LULC data in 2017) and LULC2001 (LULC data in 2001) scenarios were simulated for January and July 2017, respectively, to assess the impact of LULC changes on meteorology and fine particulate matter (PM₂.₅) concentrations in Changchun. The results show that the sensible heat flux in the urban expansion area (UEA) increased during the daytime, reaching a maximum value of 154 W/m² and 162 W/m², respectively, while the latent heat flux decreased during the daytime, reaching a maximum value of 22.84 W/m² and 180.75 W/m², respectively. Consequently, 2 m temperature (T2) increased by 4 °C and 3 °C, respectively; 10 m wind speed (WS10) increased by 1.05 m/s and 1.60 m/s, respectively; and planetary boundary layer height (PBLH) increased by 100 m and 117 m, respectively. These variations in meteorological factors can substantially impact the spatial distribution of air pollutants. In the UEA, PM₂.₅ concentrations decreased by 34 μg/m³ and 20 μg/m³ in January and July, respectively. The change in SO₄²⁻ accounted for approximately 25% of the total concentration change of PM₂.₅, with a decrease of approximately 5–6 μg/m³ during the nighttime in January. Secondary organic aerosol (SOA) formed from biogenic volatile organic compounds (BVOC) precursors (BSOA) slightly decreased owing to the reduction in croplands dominated by green vegetation. Meanwhile, PM₂.₅ concentrations in the surrounding areas of the UEA increased significantly in January. The results of the process analysis based on the CMAQ model indicate that the main reason for the spatial variation of PM₂.₅ concentrations is the enhancement of transport and diffusion in the horizontal and vertical directions in the UEA. In January, the negative contribution of vertical advection (ZADV) and horizontal advection (HADV) processes to PM₂.₅ in the UEA increased by 25 μg/m³ and 40 μg/m³, respectively. Vertical diffusion (VDIF) process caused an increase in PM₂.₅ diffusion by 40 μg/m³ and 16 μg/m³ during the daytime and nighttime in the UEA, respectively. In July, the negative contribution of VDIF and HADV processes to PM₂.₅ increased by 40 μg/m³ and 32 μg/m³ during the nighttime in the UEA, respectively.
