Overview

• Researchers combined air quality data with daily mobility patterns for a comprehensive exposure assessment.
• The study found a 2.4% increase in exposure to particulate matter when daily travel is considered.
• Southeastern Bronx, with its expressways and industries, showed the highest pollution levels.
• Hispanic communities experienced some of the highest exposure levels, with notable disparities within these groups.
• The findings highlight the potential for using city fleets as mobile pollution sensors for better air quality monitoring.
