Summary: This study investigated the association between ambient particulate matter (PM) pollution of different sizes (PM1, PM2.5, and PM10) and the risk of rehospitalization among stroke patients in China. The results showed that higher levels of PM pollution were associated with an increased risk of rehospitalization, and the association was stronger for annual average concentrations compared to seven-day average concentrations. The study also estimated the burden of stroke rehospitalization attributable to PM pollution, and found that it is responsible for a significant proportion of rehospitalization cases and associated costs.

Summary: The study shows that the particle pollution in Hefei can be divided into three stages: accumulation, outbreak, and dissipation. During the outbreak, the particulate matter first appears in the upper part of the boundary layer and then accumulates downward, leading to ground pollution. The increase in particulate matter with a diameter of 0.8-1.6 μm is significant during the outbreak, with smaller particles growing before larger ones. Sulfate particles play a crucial role in the outbreak and dissipation of pollution, and they are the most sensitive factor in the pollution process.

Summary: The study investigated the impact of PM exposure on surfactant proteins, finding a significant decrease in circulating SP-D and an increase in serum SP-A among smokers. These results suggest that circulating surfactant proteins may serve as biomarkers for respiratory injury caused by air particulate matter.

Summary: Over the past 30 years, environmental pollution, particularly ambient particulate matter, has significantly affected human health and longevity. Recent studies have demonstrated that exposure to particulate matter directly leads to respiratory system damage, including free radical peroxidation, intercellular calcium regulation imbalance, and inflammation, resulting in respiratory diseases. The respiratory microbiome plays a crucial role in lung immunity and development, and previous research has confirmed its association with chronic respiratory diseases. However, there is still limited knowledge about the changes in the respiratory microbiome in relation to particulate matter exposure and respiratory diseases. Therefore, this review aims to summarize and discuss the existing evidence, from in vivo to clinical studies, regarding the effect of particulate matter exposure on the respiratory microbiome and respiratory diseases.

Summary: The study found that ambient PM2.5 is a direct transmission mode for influenza virus infection to the human alveolar epithelium. It demonstrated a correlation between chemicals in PM2.5 and the activity of influenza viruses in the atmosphere, highlighting the importance for establishing prevention and control strategies for influenza outbreaks.

Summary: This study investigated the association between ALRI and exposure to size-specific particulate matter using different exposure metrics. The adverse effects of particulate matter exposure on ALRI hospitalizations were reconfirmed, and DECH may be a possible alternative exposure indicator for PM2.5 assessment.

Summary: In this study, we examined the concentration and composition of PM2.5 in the New York City subway system. Realtime measurements were taken on train cars and platforms, revealing higher concentrations underground than aboveground. XRF analysis showed that iron accounted for a significant portion of the PM2.5 mass, surpassing outdoor levels. The comparison with US EPA standards based on fossil fuel combustion is not appropriate, and further health impact analysis is needed.

Summary: Household humidification is beneficial for combating dry indoor air, but the use of ultrasonic humidifiers may lead to the generation of PM that can affect indoor air quality. Further investigation is needed to understand the impact of humidifier operation on human health and indoor atmospheric chemistry.

Summary: The study found that different sizes of particulate matter have varying impacts on hospitalizations for pneumonia and bronchitis in children. Additionally, the associations between different types of particulate matter and specific respiratory infections remained stable after adjustments, suggesting consistent effects of particulate matter on children's respiratory health.

Summary: The co-occurrence of PM2.5 and O-3 pollution during the warm season has a super-additive effect on respiratory admissions, contributing significantly to the burden of respiratory diseases. Prioritizing O-3 control is a cost-effective strategy for Beijing, while addressing both PM2.5 and O-3 pollution is crucial.

Summary: Plant leaves can accumulate particulate matter from the air, with different plant species having varying capacities for retention. Some plants demonstrated strong retention capacity for PM particles, while others had weaker retention capacity. These findings provide a scientific basis for using plants to mitigate particulate air pollution.

Summary: This article discusses possible violations of the assumption of no multiple versions of treatment in studies on outdoor PM2.5 air pollution. Differences in particle composition can lead to different health risks for the same treatment level. Confounding bias may occur if these factors are not identified and controlled for in the analysis. Violations of this assumption can be an underappreciated source of bias in studies on outdoor PM2.5.

Summary: Nine out of 10 people breathe air that does not meet World Health Organization pollution limits, leading to approximately 8 million deaths annually. Particulate matter is the most dangerous form of air pollution, causing inflammatory and oxidative tissue damage. This review will summarize the impact of particulate matter on physiological systems, referring to relevant epidemiological and toxicological studies.
