Article Abstract
This paper investigates the multifractal characteristics of six air pollutants using the coupling detrended fluctuation analysis method. The results show that coupling correlations exist among the air pollutants and have multifractal characteristics. The sources of multifractality are identified using the chi square test. The coupling strengths between different pollutants are quantified. In addition, the coupling contribution of a series in the haze system is calculated, and SO, as the main pollutant, plays a key role in the pollution system. Moreover, the Kriging interpolation method is used to analyze the spatial characteristic on coupling contribution of SO. The spatial analysis of coupling strength for air pollutants will provide an effective approach for pollution control.

Epidemiological studies have already established associations between air pollutants and adverse health outcomes, but the causal associations between air pollutants and chest pain (CP) and gingival pain (GP) remain unclear. This study aimed to explore the potential causal effects of air pollutants on CP and GP. Utilizing genome-wide association study summary statistics from European-ancestry populations, we conducted bidirectional two-sample Mendelian randomization (MR) analyses.

Recently, the atmospheric aerosol surface, which is reported to be quite acidic, is recognized as an important microreactive medium for atmospheric chemistry, profoundly impacting air quality and global climate. Nevertheless, the molecular-level understanding of the effect of surface-bound acids on atmospheric chemical reactions remains limited. Herein, the reactions between CO and NH/amines at the air-water interface with organic acids are investigated using combined molecular dynamic simulations and quantum chemical calculations.

Limited research has examined the relationships of co-exposure to air pollutants, temperature, and road traffic noise with chronic kidney disease (CKD) incidence and the interaction between PM and temperature. To address this gap, the present study explored these associations and interactions in Taiwan. A cohort of 3,041 older individuals (aged ≥55 years) was recruited in 2009 and followed until 2019.

Airborne pathogens and pollution control typically necessitate multiple membranes, each specializing in efficient aerosol filtration, moisture regulation, or antimicrobial protection. Integrating all these functions into a single membrane is highly advantageous but remains inherently challenging due to material incompatibility and inevitable performance trade-offs. Here, we present a photoactive Janus nanofibrous membrane for highly efficient air purification, engineered via sequential electrospinning.
