Effect of ventilation Particle number concentrations in vehicle air roughly 45% of on-road levels NO/NO2: no clear difference during ventilation Effect of recirculation Drastic decrease in number concentration in vehicle air (<15% of on road level) NO/NO2: no difference; steady level? Exposure: NO and NO2: similar as on the road Particle number: less but still above urban background while ventilating Car’s cabin does (indeed) not protect against traffic pollution Setting a car’s ventilation system to “recirculate” is the best way to reduce exposure to particulate pollution
