Key Points

This research aims to evaluate the impact of traffic restrictions on urban air quality, specifically focusing on particulate matter levels and sources.
Examined particulate matter concentrations in a coastal urban environment under strict traffic restrictions.
Analyzed the chemical composition and sources of particulate matter to identify contributions from traffic emissions.
Utilized air quality monitoring stations across the urban area for data collection.
Traffic restrictions led to a significant reduction in particulate matter concentrations, with levels decreasing by 30% (p<0.01).
Chemical analysis revealed that traffic emissions were identified as the primary source of particulate matter, accounting for 60% of the overall composition.
Overall air quality improved, showcasing the effectiveness of traffic restrictions in urban environments.

Reveals effects of traffic restrictions on particulate matter in urban areas, suggesting improved air quality outcomes.

sources in a coastal urban environment, highlighting the importance of reducing traffic-related emissions to improve urban air quality.
