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 study found that forced resuspension is an effective method for reducing deposited particulate matter in indoor environments, with four-way airflow being more effective than one-way airflow. The orientation and velocity of the airflow have an impact on the resuspension and removal efficiency of particulates, with a flow velocity of 5 m/s or higher being necessary to resuspend deposited particulate matter.

Summary: This study examines the composition, size, and dispersion of settleable particulate matter (SePM) in water, revealing high levels of metal elements, especially in areas influenced by the steel and iron industry. Agglomeration of nanoparticles and dissociation in water contribute to water pollution effects from SePM.

Summary: The study aimed to determine ventilation conditions for managing indoor air quality during cooking in a typical South Korean residential home. The PM10 and PM2.5 concentrations varied depending on ventilation conditions, but were high when inappropriate methods were used. Using appropriate ventilation conditions is effective in reducing PM10 and PM2.5 generated during cooking.

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 evaluates the contribution of emission sectors and fuels to fine particulate matter (PM2.5) in South Asia, finding that residential combustion, industry, and power generation are the primary contributors to PM2.5-related mortality. Solid biofuel is the leading combustible fuel contributing to PM2.5-attributable mortality, followed by coal and oil and gas. State-level analyses reveal higher contributions from residential combustion in states with high ambient PM2.5 levels. Reducing emissions from traditional energy sources across multiple sectors in South Asia can improve population health.

Summary: Sub-Saharan Africa is experiencing rapid urbanization, with air pollution emerging as a major concern in growing cities, especially in Accra, Ghana. The study found that commercial, business, and industrial areas have the highest levels of PM2.5 pollution, with concentrations 2-4 times higher than WHO guidelines. Additionally, PM2.5 levels peak during the dry dusty Harmattan period, and have decreased by 50% compared to measurements in 2006-2007. Effective policies are needed to reduce pollution levels and protect public health in urban areas.

Summary: Oxidative potential (OP) is a parameter that can indicate the ability of particulate matter (PM) to generate reactive oxygen species (ROS). This study evaluated the OP of PM10, PM2.5, and PM1.0 samples in two cities of Chile. The results showed differences in OP between cities, PM size fractions, and seasons, and a strong correlation between OP and certain metals and meteorological variables. Based on these findings, it is suggested that OP be used as a complementary measure to PM mass concentration in air quality management.

Summary: Agricultural operations are significant sources of organic dust containing particulate matter and endotoxins, which can have negative health consequences for both humans and animals. This study in Belgium found associations between PM fractions and endotoxin concentrations in calf barns with lung consolidation, respiratory tract inflammation, and infection in group-housed calves. Strategies to control fine dust fractions in calf barns may benefit respiratory health for humans and animals.

Summary: Emerging evidence suggests that ambient particulate matter (PM) has negative effects on male fertility, especially the association between ambient PM2.5 exposure and semen quality. Long-term exposure during the past 70-90 days and 0-9 days, as well as throughout spermatogenesis, has significant effects on semen quality.

Summary: Air quality, both indoor and outdoor, is crucial for public health. This study introduces a new methodology using low-cost sensors and source apportionment techniques to understand the importance of different air pollution sources on indoor air quality. The results demonstrate the highest concentrations of PM in the bedroom, the highest PM spikes in the kitchen during cooking times, and the highest PM1 concentrations in the office due to outdoor infiltration. Source apportionment analysis shows that up to 95% of PM1 comes from outdoor sources in all rooms.

Summary: The diverse composition and abundance of suspended particulate matter make it difficult to identify the exact precursors for atmospheric pollutants. Phytoliths, microscopic biogenic silica deposited by plants, are dispersed into the atmosphere through dust storms, forest fires, and stubble burning. Due to their durability, chemical composition, and diverse morphology, phytoliths are considered a possible particulate matter that can impact air quality, climate, and human health. Estimating the phytolith particulate matter, its toxicity, and environmental impacts will help develop effective policies for improving air quality and reducing health risks.

Summary: Daily activities performed by music instructors generate high sound levels that could potentially lead to overexposure. Approximately one-third of daily exposures exceeded recommended limits, with brass and conducting instructors having the highest exposures. Conductors experienced the highest between-day variability in daily exposures.

Summary: The study surveyed commercially available filter media to potentially substitute for N95 respirators in 3D-printed masks. Results indicated that while some filter media could replace those in traditional N95 masks, their use in 3D-printed masks led to decreased efficiency and increased breathing resistance.

Summary: Serum samples from both rural and urban communities were analyzed for 74 sulfated metabolites of PCBs. The urban group showed significantly higher concentrations of PCB sulfates compared to the rural group. Several specific congeners contributed to the majority of the assessed PCB sulfates. The distribution of PCB sulfates differed from previous studies in the same communities. There were location and mother-child dyad-specific correlations.

Summary: This study investigated the immunomodulatory effects of inhalation exposure to copper oxide nanoparticles (CuO NPs) in different immune conditions. The results showed that CuO NP exposure decreased T(H)1 and T(H)2 cells and increased T-bet(+) Treg cells in healthy mice. However, CuO NP inhalation exposure resulted in decreased T(H)2 responses and increased T-bet(+) Treg cells in mice with house dust mite (HDM) asthma, and increased T(H)2 cells in AIT-treated asthmatic mice.
