Exposure to clean air
"Subjects will be exposed to filtered indoor air (clean air) for 4 hours in the Fraunhofer Environmental Exposure Chamber. The chamber can accommodate up to 18 subjects, is ventilated by HEPA-filtered and conditioned air, ensuring a constant humidity (40 ± 10%), temperature (22 ± 2°C), and airflow (1500 ± 100 m3/hr). During exposure they will perform an intermittent bicycle ergometer activity at 50 W for 10 minutes alternating with 20 minutes rest."
Exposure to urban air
"Subjects will be brought to a traffic dense urban region (urban air) with high traffic density and increased levels of particulate matter and vehicle emissions. Subjects will stay in this area for 4 hours. During exposure, all subjects will walk together with study staff. Rest periods are only allowed outside. Intervals of activity and rest will be similar to the clean air regimen."
