Abstract
Outdoor measurements provided by continuous monitors are inappropriate to
assess nitrogen dioxide personal exposure because people spend most of their
time in indoor environments. A passive sampler is a good alternative.
Unfortunately, it can only provide an integrated concentration measure due to the
long sampling time required to obtain reliable results.
The department developed a new passive sampler which is 45 times as
sensitive as a Palmes tube and can provide reliable measures on a very short
sampling period (in the order of one hour).
Uptake rate and environmental factors affecting this sampler performances
(such as wind speed, temperature, humidity) have been determined thanks to an
exposure chamber.
It was tested in a
