Air Pollution Exposure: Measurement

Exposure Assessment:  Measurement

This body of work is defined by pioneering research that uses on-board and portable instruments to directly measure human exposure to air pollutants in real-world microenvironments. Novel contributions include characterizing exposure in vehicles, public transit systems, schools, and even a college football stadium. This research provides high-resolution data on the concentration of pollutants such as PM_2.5 and CO, offering new insights into the sources of variability in exposure and providing a data-driven basis for public health interventions that go beyond ambient air monitoring.
