Summary: With increasing concerns about the health effects of particulate matter (PM), controlling indoor PM has become crucial for occupants' well-being. Both active strategies, such as air purification and high-performance filtering, and passive strategies like air-tightness and compartmentalization, have shown promise in controlling indoor PM. In this study, a multi-zone-based method was investigated to evaluate the effectiveness of passive strategies. The results indicated that the multi-zone method accurately estimated outdoor particle transport and indoor PM concentrations, considering factors such as airflow rate, particle size, and outdoor temperature changes.

Summary: An inhalation model for particulate matter (PM) considering exercise load was established to assess its impact on residents' travel health. PM concentrations were collected at different transportation spaces, such as walking, bicycle, bus, taxi, and subway, using PM detectors. A multiple linear regression model, adjusted by road greening, was used to investigate the influencing factors on PM concentration. The air inhalation model, considering individual heart rate (HR) and characteristics, was obtained. The proposed model estimates PM2.5 and PM10 inhalation during a complete trip based on air inhalation per time unit, travel time, and PM concentration. Analysis of experimental data in Xi'an revealed significant differences in PM concentrations between taxi, bus, and subway carriages and environmental monitoring stations, while the differences were not significant in sidewalk, non-motorized lane, taxi station, bus station, subway concourse, and subway platform locations. PM concentration and humidity in the background environment positively influenced PM concentration in the transportation environment, while temperature and wind speed had negative effects. The mean values of air inhalation per time unit for males and females in each mode ranged from 9.6-26.8 L/min and 9.8-27.8 L/min, respectively. Exposure time in non-motorized transportation significantly affected PM inhalation, with walking connections and waiting in motorized transportation being the main contributing factors. The study results can be used to predict travelers' PM inhalation during completed trips and provide recommendations for choosing a healthier mode of transportation.

Summary: This paper investigates the relationship between traffic-related pollutant concentrations at pedestrian level and indoor pollutant concentrations in different rooms of a standard building. Through CFD modelling, the study simulates wind flow and pollutant dispersion both outdoors and indoors. The results show that indoor pollutant concentrations vary significantly depending on the floor, window configuration, wind direction, and incidence angle. Generally, indoor concentrations decrease with floor, but the extent of decrease varies across scenarios and rooms. Indoor concentrations higher than the street average are found in some rooms due to high pollutant concentrations near open windows. However, on average, indoor concentrations are lower than those at pedestrian level. The average ratio between indoor and outdoor concentrations is 0.56 +/- 0.24, consistent with previous studies. This paper provides a unified approach for assessing air quality in indoor and outdoor environments.

Summary: Urban vegetable gardens are often featured in cities to promote a sustainable lifestyle. However, pollution levels in cities, especially from traffic, can be high. Microplastics have emerged as a concern due to their environmental contamination and potential health impacts. This study compared the levels of microplastics in lettuce plants from urban gardens in Lisbon with those from a rural area and supermarket-bought samples. Microplastics were found in all washed leaves, with higher levels in lettuce grown in urban gardens with high traffic density. Weak correlations were found between microplastics content and concentrations of certain elements that are considered traffic-source tracers. These findings shed light on the microplastic contamination of vegetables grown in urban environments and the potential health risks from dietary intake.

Summary: The hygroscopic properties of atmospheric aerosol in a suburban environment in Athens, Greece, were studied. The growth factor distribution probability density function (GF-PDF) and mixing state were determined using a hygroscopicity tandem differential mobility analyzer (HTDMA). The results showed distinct hygroscopic ranges, with a non- and/or slightly hygroscopic mode (GF < 1.12) and a moderately hygroscopic mode (GF > 1.12), indicative of local/urban emissions and background aerosol influences. Cluster analysis revealed the link between aerosol hygroscopicity and emission sources and formation processes. The findings suggest that particles of similar nature and origin were present across the 50 nm and 80 nm sizes.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
