Summary: This study investigated the effects of six common indoor ornamental plants and three types of microalgae on the removal of air pollutants. The results showed that microalgae, especially C. vulgaris, were more effective in removing PM2.5, PM10, formaldehyde, and VOCs. Physical methods were weaker compared to plants and microalgae in terms of increasing relative humidity and oxygen content. Overall, microalgae, especially C. vulgaris, can efficiently purify indoor air pollutants.

Summary: Indoor air quality in nursing homes often exceeds outdoor levels, which may adversely affect the health of elderly residents who are more susceptible to air pollutants. Regular monitoring and improvement of indoor air quality in nursing homes can reduce medical expenditures and improve residents' quality of life.

Summary: Exposure to particulate matter (PM) is an important risk factor for morbidity and mortality. The study measured indoor PM concentrations in a large-scale birth cohort, identifying important predictors such as indoor PM10-2.5, outdoor PM2.5, indoor smoking, and temperature. Findings highlight the importance of reducing outdoor PM concentrations, avoiding indoor smoking, and using air cleaners to improve indoor air quality.

Summary: This study focuses on catalytic oxidation of formaldehyde into CO2 at room temperature using platinum supported by waste eggshell. The addition of potassium enhances the catalytic activity, with reaction pathways involving dioxymethylene, formate, and carbon monoxide intermediates. The research opens new possibilities for developing high-performance biowaste-derived catalysts without external energy sources.

Summary: In this crossover study of 48 adults, it was found that traffic-related air pollution during commuting has health effects, but these effects can be mitigated by the use of cabin air filtration. The study results showed that cabin air filtration can reduce the concentrations of particulate air pollutants such as ultrafine particles, volatile organic compounds, and black carbon by almost a third.

Summary: The growth of India's food delivery sector has led to an increase in the number of delivery persons on the road, exposing them to traffic-related air pollution. This study assessed the exposure of delivery persons in Ghaziabad to particulate matter and volatile organic compounds, finding that their exposure levels exhibited significant diurnal variation, with higher levels at night.

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.

Summary: The study found a correlation between PM2.5 and the risks of weight gain and obesity, especially at PM2.5 concentrations below the national standard. Results were consistent across different sensitivity analyses, suggesting that PM2.5 air pollution may contribute to obesity and weight gain.

Summary: The rapidly growing vehicle population is a crucial contributor to severe air pollution and public health issues, particularly in urban areas where vehicles are important sources of air pollutants. Limited studies have focused on the variability in in-vehicle concentrations of traffic-related air pollutants and the impact of filtration devices. Results indicate that using high-efficiency cabin air filters can significantly improve PM2.5 filtration efficiency, enhancing in-cabin air quality and reducing health risks for drivers.

Summary: Volatile organic compounds (VOCs) emitted from building and vehicle cabin materials have a significant impact on indoor and in-cabin air quality and human health. This study investigated the effect of in-cabin chemistry on VOC emissions by conducting small-scale chamber tests on two types of vehicle cabin materials and one furniture material. The results showed that ozone had a significant impact on the concentrations of aldehydes and ketones, but had little effect on the concentrations of benzene series. This study demonstrated that ozone can react with VOCs emitted from various materials to produce aldehydes and ketones, reducing indoor and in-cabin air quality.

Summary: The popularity of facemasks has increased in northern China due to severe air pollution. While wearing facemasks can reduce exposure to particulate matter, the protection is limited as people spend most of their time indoors. Installing indoor air purifiers is a more effective strategy for long-term protection against particulate matter exposure.

Summary: Catalytic oxidation is effective in removing stable CO and light alkanes. Noble metal catalysts show excellent performance due to their strong chemisorption of CO and high activity towards methyl dehydrogenation. The interfacial effects dominate the charge states of noble metals through the metal-support interactions, thereby governing their stability and activation effects to reactants.

Summary: This study compares the particle and gas phase emission factors between cooking with an air fryer and a pan, finding that air frying chicken wings and breast results in higher PM10 emission factors compared to pan cooking. However, by increasing the amount of oil, air frying can achieve higher PM10 emission factors for French fries and asparagus. The emission factors of volatile organic compounds (VOCs) are also generally higher for air frying.
