Summary: This study investigated the characteristics of airborne archaea in Beijing during springtime, revealing soil as the primary source for releasing archaea into the environment. It was found that air quality and sandstorms can impact the abundance of airborne archaea, and dispersal-related neutral processes play a crucial role in shaping the structure of the archaeal assembly.

Summary: Rapid urbanization has led to a significant amount of construction waste, which can have negative impacts on the living environment of residents. Dust-proof nets have been implemented in construction sites to reduce pollution from dust particles, and this study used Earth observation techniques to monitor their efficacy. The research conducted a case study in Zhengzhou, China, using multispectral remote sensing and a classification method to identify construction waste and dust-proof nets. The results showed that the classification method was effective in tracking solid waste management and air pollutant concentrations, contributing to better urban environmental governance and achieving sustainable development goals.

Summary: A comprehensive study was conducted to investigate the formation process of winter haze pollution in Jinan, China, using ground and satellite observation data from January 2 to January 13, 2022. Three haze pollution events were identified during this period, with event 2 lasting longer and exhibiting a cumulative growth state. The combination of local and nearby pollutant emissions was the main cause of this event. Weather factors such as lower wind speeds, stable inversion layer, and higher relative humidity contributed to pollution accumulation and haze event formations. The study's results provide important insights into the formation of haze pollution in Jinan and can aid in regional climate change research and government efforts to prevent and control haze pollution in eastern China.

Summary: This study conducted a multi-city time-series analysis in Anhui Province, China to explore the relationship between short-term exposure to air pollutants and the risk of outpatient visits for osteoarthritis (OA). The results showed that particulate matter (PM2.5 and PM10) was associated with increased risk of OA outpatient visits, while gaseous pollutants (SO2, O3, and CO) did not show any significant association. Additionally, the risk of OA varied between different seasons.

Summary: In this article, a new real-time scene recovery framework is proposed to restore degraded images under different weather/imaging conditions. The method introduces a rank-one matrix to characterize the degradation phenomenon and achieves real-time recovery. Experimental results demonstrate that the proposed method outperforms several state-of-the-art imaging methods in terms of efficiency and robustness.

Summary: This study analyzed ground-based and satellite data from December 1, 2020 to January 12, 2021 to investigate the formation process of haze events in Jinan area during winter. Two typical types of haze pollution were identified in the area, with different causes and characteristics. Local pollutant emissions and pollutants transported from surrounding areas contribute to type 1 haze pollution, while a mixture of long-range transported dust and locally emitted pollutants cause type 2 haze pollution. Unfavorable meteorological factors such as stable inversion layer, continuous cold high-pressure system, high relative humidity, and low wind speed play crucial roles in the formation of both types of haze pollution.

Summary: After a year of observation, it was found that foggy, haze, dust, and haze-fog days have a significant impact on the concentration and viability of bacteria in the air, altering the seasonal variation trend of total airborne microbes and non-viable bacteria. Different weather conditions have varying effects on bacterial viability, with special weather events negatively affecting certain bacterial species.

Summary: The study in Zibo, China during autumn and winter found that secondary aerosols had a significant impact on PM2.5, closely related to relative humidity, slow winds, and precursor materials. Photochemistry played a major role in the secondary formation of NO3-, with peak levels occurring during morning and evening rush hours. Additionally, smaller particles were found to contribute more to slight pollution, while PM2.5 played a larger role during severe haze events.

Summary: Serious PAHs pollution was found in residential dust in eight cities across China, mainly from biofuel combustion. The concentrations of PAHs in residential dust exceeded acceptable levels, and the combustion processes and automobile exhaust emissions were identified as the main sources. Indoor air environmental factors, household characteristics, and residents' behavioral lifestyles may affect the concentration of PAHs in residential dust.

Summary: This study analyzed the records of 160,555 ischemic stroke hospitalizations in nine cities in Sichuan, China and found that short-term exposure to air pollution is associated with increased hospitalizations for stroke. The study also assessed the economic burden associated with these hospitalizations. The results showed that short-term exposure to PM2.5, PM10, O3, and CO can lead to increased hospitalizations for stroke and a quantifiably greater economic burden.
