Summary: The study utilized fiber filter dust removal equipment and ultrasonic atomization technology to enhance the capture efficiency of fine particulate matters. A novel ultrasonic atomized dust removal system was developed through numerical simulations and experimental results. Adjusting the thickness of the filter and filling rate significantly improved the dust removal efficiency at low dust concentration, while these adjustments had little impact at high dust concentration.

Summary: The study conducted in downtown Lanzhou, Northwest China, found that vehicle emissions were the major source of PM pollution, especially in winter and autumn when they made significant contributions. With the reduction in industrial emissions and increase in vehicle numbers in China in recent years, vehicle emissions are projected to become the largest source of urban PM pollution. Efforts to control vehicle emissions, such as promoting clean-energy vehicles and encouraging public transportation, are crucial for sustainable improvement of air quality in Lanzhou and other Chinese cities.

Summary: This study aimed to assess the trimester-specific effects of PM2.5 and PM1 prior to the diagnosis of de novo HDP. The results showed that exposure to PM2.5 and PM1 during the first and early second trimesters was positively associated with the risk of de novo HDP. Pregnant women with maternal age above 35 and low maternal education level had a stronger association between fine particulate matter exposure and the risk of HDP. These findings highlight the importance of fine particulate matter in the development of hypertensive disorders of pregnancy.

Summary: Measurements were conducted in a laboratory kitchen to investigate the types, emission factors, and ozone formation potential (OFP) of non-methane hydrocarbons (NMHCs) generated during various cooking processes. The results showed that NMHC emission factors varied for different types of cooking activities and types of food materials. Trichloroethylene, toluene, n-dodecane, isoprene, ethylene, and 3-methylpentane were identified as the NMHC species with the greatest OFPs during cooking. These findings provide valuable information on the impact of Chinese kitchens on indoor air quality.

Summary: By quantifying the absorption of black carbon (BC), brown carbon (BrC) and the lensing effect, it was found that BrC dominates the total absorption at 450 nm, and the largest absorption contribution proportion of BrC could reach 78.3% during heavy pollution. The average absorption enhancement (E-abs) at 530 nm was only 1.38, indicating that BC is not coated well here. The absorption of polycyclic aromatic nitrogen heterocycles (PANHs) is comparable to that of nitro-aromatics, which should attract more attention to their impact on climate radiative forcing.

Summary: This study investigated the importance of atmospheric deposition on the phosphorus biological cycle and the distribution of different phosphorus forms in different seasons and particle sizes in Shanghai. The results showed a bimodal distribution of total phosphorus, mainly contributed by mineral dust in the coarse mode and related to anthropogenic and combustion emissions in the fine mode. Dissolved inorganic phosphorus and dissolved organic phosphorus showed a bimodal distribution in spring and summer, and a unimodal distribution dominated by a fine mode in autumn and winter. The study also identified the sources of phosphorus in atmospheric aerosols and estimated the deposition flux of total dissolved phosphorus.

Summary: This comprehensive study found that mobile sources and residential solid fuel burning are sensitive sources of potential secondary pollutants and potential inhalation health risks, respectively. Despite accounting for only 22.7% of the total mass, residential VOCs contribute significantly to both inhalation non-cancer risk (57.4%) and cancer risk (47.3%). Therefore, more attention should be paid to the formation of secondary pollutants from mobile sources, while policy priority should be given to reducing health risks from residential solid fuel burning.

Summary: In this study, sulfate (SO42-) samples from three haze events were analyzed for sulfur isotope signals. The results showed that after considering coal combustion and atmospheric oxidation, the source apportionment results of SO42- were highly consistent with those obtained from the Positive Matrix Factorization model. The sulfur isotope analysis, especially for the contribution of secondary SO42-, provided more accurate results by considering the fractionation from coal combustion. Therefore, sulfur isotopes were considered as a more sensitive pollution indicator than SO2 concentration, providing more reliable evidence for SO2 emission control.

Summary: This study investigated the presence of cyanobacteria on the pre-filter of HVAC systems and found that the concentrations were highest in autumn and significantly higher compared to winter and summer. The airborne transportation of aquatic and terrestrial cyanobacteria contributed to their presence on the pre-filter. The dominant cyanobacteria families identified were Chroococcidiopsaceae, norank_cyanobacteriales, Nostocaceae, and Paraspirulinaceae. Some detected genera, such as Nodularia sp., Pseudanabaena sp., and Leptolyngbya sp., potentially produced cyanobacterial toxins that could pose a threat to human health. This study provides new insights into the distribution of cyanobacteria outside of aquatic habitats.

Summary: A regional online chemical weather model, WRF/CUACE, is used to investigate the impact of cloud chemistry on SO2 and sulfate levels in typical regions of China. The cloud chemistry scheme is found to accurately reproduce observed cloud consumption and sulfate production. During a heavy pollution episode, cloud chemistry leads to a significant reduction in SO2 and an increase in sulfate. The Sichuan Basin is the most affected region, followed by the Yangtze River Delta and the southeast of the North China Plain.

Summary: The greening impacts in China from 2000 to 2017 increased vegetated areas and BVOC emissions. Accurate estimation of BVOC emissions is critical to understand their impacts on air quality. Different leaf area index (LAI) and land cover (LC) datasets were used to investigate the impact on BVOC emissions, and the effects on O-3 and SOA were evaluated. Results show that changing LAI and LC datasets of the model input has an impact on BVOC estimations, with the combination of C3S LC and GLASS LAI performing better. The uncertainties in MEGAN inputs should be fully considered in future O-3 and SOA simulations.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.
