Urban vegetation affects air quality through influencing pollutant deposition and dispersion.
Both processes are described by many existing models and experiments, on-site and in …

Cities are facing significant challenges due to low outdoor air quality. Hence, a growing
number of studies have been conducted to develop strategies for improving air quality. This …

Improving city breathability has been confirmed as one feasible measure to improve
pollutant dilution in the urban canopy layer (UCL). Building height variability enhances …

High-rise deep street canyons usually experience poor ventilation and large vehicular
pollutant exposure to residents in near-road buildings. Investigations are still required to …

Urbanization itself is a major and furthermost imperative contributor to the release of
microplastics into the environments. As cities grow and develop, more plastic products are …

Validated by experimental data, this paper performs computational fluid dynamics (CFD)
simulations to investigate the influence of tree plantings on urban airflow and vehicular CO …

Environmental concerns have been raised on the adverse health effects of vehicle
emissions in micro-scale traffic-crowded street canyons, especially for pedestrians and …

Vehicular pollutant exposure of residents and pedestrians in high-rise deep street canyons
with viaducts and noise barriers requires special concerns because the ventilation capacity …

Air pollution is a global problem, which needs to be understood and controlled to ensure a
healthy environment and inform sustainable development. Urban areas have been …

Recent studies indicate the necessity of addressing traffic-related air pollution in urban
environments, as street canyons are known for their lack of natural ventilation and increased …
