Summary: This study demonstrates the efficacy of roadside green infrastructure (GI) in improving local air quality by capturing and reducing airborne particulate matter (PM). A recently installed 'tredge' was found to be effective in intercepting and depositing PM, resulting in significant reduction in exposure in a school playground setting. The findings suggest that GI can be a cost-effective mitigation strategy.

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: Urban areas with trees offer various ecosystem services to residents, including the removal of air pollutants like particulate matter. This study in Bogota, Colombia investigated the variation of intercepted particulate matter concentration (IPMC) by tree leaves, finding that IPMC decreased as PM2.5 concentration increased. Species like Ligustrum-lucidum and Lafoensia-acuminata showed the strongest trend of decreasing IPMC with increasing PM2.5 concentration, with larger leaf area associated with higher IPMC. Additionally, higher wind speeds were linked to higher PM2.5 concentrations and decreased leaf IPMC.

Summary: Oxidative stress in cells is caused by an imbalance between oxidant production and the antioxidant system's ability to detoxify reactive products. This stress can lead to genotoxic damage, mutation, and play a role in carcinogenesis. Particulate matter (PM) air pollution has been identified as a cancer risk factor, and evidence suggests that PM-induced oxidative stress can contribute to various events promoting carcinogenesis. This review emphasizes the importance of studying the oxidative and genotoxic mechanisms associated with PM in malignant cell transformation and calls for more accurate approaches to assess its carcinogenic potential.

Summary: The study found that plants at all layers of urban forests accumulate particulate matter (PM). Herbaceous plants growing along roadsides efficiently accumulate PM, while trees and shrubs accumulate PM that was not deposited on herbaceous plants. As the distance from the road into the forest increases, the PM content on herbaceous plants decreases and the accumulation on trees and shrubs increases. The results demonstrate the important role of meadow vegetation and urban forests in air purification.

Summary: Green walls offer a significant but underexplored potential in mitigating urban PM pollution. There are still uncertainties and challenges regarding the effectiveness and optimal plant characteristics for PM deposition on green walls, which require further research and validation. Rainfall plays an important role in the PM deposition pathway, although it is not a crucial factor for sustaining PM deposition on plant leaves.

Summary: Depositions of trace elements of air particulates in the atmosphere have been studied, and the impacts of dry deposition flux and Saharan dust intrusion on elemental concentrations have been determined. The concentrations of trace elements in rural and urban particulate matter were characterized, and dry deposition fluxes were found to be higher in coarse particulate matter compared to fine particulate matter. Additionally, the modeling analysis showed that the highest daily surface dust concentration was observed in the central and south-west of Turkey during the peak period of Saharan dust transport in March.

Summary: The emergence of multidrug-resistant bacteria poses a significant threat to global public health. Majority of clinical bacteria are found to be multidrug-resistant, with antibiotic resistance genes on their plasmids that can be horizontally transferred. The presence of optimal concentration of antibiotics or heavy metals facilitates horizontal gene transfer. High levels of arsenic in water were discovered in the Shukratal region of India, corresponding to high serum arsenic levels in infected individuals and increased antibiotic resistance in bacterial strains isolated from that area. This research highlights the imminent threats to global health due to improper waste disposal, increased antibiotic concentrations and human interference.

Summary: This study investigates the energy impact of air handling units (AHUs) located in different positions and orientations on a building rooftop on the energy demands of air filtration. The results show that the ventilation PM2.5 concentration is equal to the ambient when positioned near the windward wall. A decrease in the filter loading rate of 33% and 60% occurs at wind speeds of 7.5 m/s and 2.5 m/s at the leeward wall. When the AHU is positioned on the windward side, there is no energy savings, but there is a reduction in energy consumption of 9.8% at the centre and 19.4% at the leeward side. Comparing the effect of wind orientation for identical AHU positions on the rooftop centre resulted in a 26-35% reduction in AE and incurred energy savings of 25.8%.

Summary: This critical review analyzes the feasibility of mitigation and adaptation measures for sand and dust storms (SDS) in the Eastern Mediterranean Region (EMR). It concludes that implementing appropriate measures at the local level is possible, but poses a new challenge at a wider scale. The EMR, being at the intersection of three major SDS areas with diverse economic, political, and social conditions, adds complexity to this challenge. The review also highlights the lack of adaptation measures in the region and identifies successful mitigation strategies for similar environmental issues.

Summary: This review summarizes the emissions and chemical composition of ultrafine particles (UFPs) from residential solid fuel combustion, and evaluates the factors affecting their emissions and the effectiveness of mitigation strategies. The study found that emissions are influenced by fuel quality, stove types, and combustion conditions. UFPs are mainly emitted during the coking and flaming phases of combustion. Improved stoves, mineral additives, and small-scale electrostatic precipitators have limited effectiveness in reducing UFP emissions. Further research on different improved heating stoves is needed to better understand their emissions of UFPs.

Summary: The impact of bicycle lane designs on cyclist exposure to air pollution is a significant concern. This study found that in the city of Medellin, Colombia, the sections without dedicated bicycle lanes had the highest PM2.5 exposure and inhaled dose. Cyclists had higher PM2.5 exposure and inhaled dose during morning peak hours compared to evening peak and off-peak hours. Segregated cycling lanes on the sidewalk can considerably lower PM2.5 exposure and inhaled doses for cyclists.

The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
