Abstract:
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
