Summary: The study found that household fine particulate matter (PM2.5) pollution in China is severe, especially in rural areas where the HPL is higher than in urban areas. There are significant differences in PM2.5 concentrations in households across different seasons and geographic locations. Urgent measures are needed to reduce indoor pollution and protect residents' health.

Summary: Household heating with wood stoves in rural areas of the US can lead to elevated indoor PM2.5 concentrations. Failure to clean chimneys and use of low-quality stoves can significantly increase PM2.5 levels. Regionally appropriate interventions such as upgrading to higher-quality stoves and regular chimney cleaning are essential for improving indoor air quality in rural wood-burning regions.

Summary: Traditional cooking with solid fuels creates household air pollution, leading to millions of premature deaths worldwide. This study analyzed the impact of household and personal variables on exposure to fine particulate matter and black carbon. Stove type was found to have the greatest influence on exposure. Future research should include tracking participants' cooking behaviors and daily activities to further understand exposure variations.

Summary: This study proposes an organic film-based method to assess semivolatile organic compound (SVOC) exposure in indoor environments. Various phthalate exposure pathways were examined in children and adults, and the findings provide important baseline data for future research in health risk assessments and SVOC exposure utilizing organic films.

Summary: The study assessed daily exposure levels of EPFRs for urban residents in Beijing, finding that carbon-centered radicals dominated in winter, while oxygen-centered radicals dominated in summer. Coal combustion in winter was identified as a key influencing factor, and an intuitive assessment concluded that one urban resident may inhale the equivalent of 46 cigarettes per day in EPFRs. Further research on the health risks of these free radicals, especially during winter, is recommended.

Summary: The study found that personal use of air filtration units can significantly reduce indoor fine particulate matter concentrations by 11% to 82% under real-world situations. However, factors affecting the reduction of indoor particulate matter concentrations include geographical location, filtration technology, indoor environment, and air pollution sources.

Summary: Particulate matter (PM) pollution is a significant environmental concern due to its negative impact on human health. This study evaluates the daily exposure and inhaled dose of PM chemical compounds by integrating the concentrations measured in the micro-environments (MEs) where children spend most of their time. Results indicate that homes and schools contribute the most to children's daily exposure and inhaled dose. The study also highlights the high contribution of indoor sources to the organic fraction of particles, particularly in schools where mineral elements from dust resuspension and chalk usage stand out. Additionally, outdoor activities result in higher inhalation rates, leading to a higher contribution of outdoor particles to the inhaled dose. Overall, this study emphasizes the importance of indoor air quality in relation to children's exposure and health.

Summary: This study proposes a new 3D approach for modeling indoor airborne particulate matter (PM) concentration using cellular automata (CA) framework. By considering four major PM transport mechanisms, the CA approach achieves high accuracy and efficiency in numerical simulations, making it a useful tool for 3D simulations of indoor PM transport and distribution.

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: This study characterized particle size distribution from biomass-related pollution and assessed lung-deposited doses using multiple-path deposition modeling. Results showed high PM2.5 concentrations in kitchen and personal exposures, with a primary accumulation mode at 0.21 µm and a secondary coarse mode at 3.17 µm. Additionally, the study provides unique data on lung deposition of biomass smoke.

Summary: This study investigated the impact of air purifiers in removing different particulate matter in dormitories, and found that smoking significantly lowered the efficiency of removing PM10, PM2.5, PM1, and PNC. However, using air purifiers can reduce the levels of PM10 and PM2.5, even below the WHO guideline, in non-smoker rooms, reducing the non-carcinogenic risks of exposure.

Summary: Air pollution levels in the United States have decreased, but racial-ethnic exposure disparities persist. Targeting specific locations for emission reductions can eliminate national exposure inequalities, while existing regulatory strategies require significant reductions. Additionally, location-specific strategies are found to be the most effective in reducing overall exposure and national inequalities.

Summary: This study identified an association between prenatal exposure to PM2.5 and placental gene expression, particularly in the first half of pregnancy. Offspring sex may also play a role in modulating this association, with a positive correlation observed in males and a negative correlation in females.
