Abstract

Laboratory tests for the development of a new high uptake rate passive sampler for nitrogen dioxide measurements A. Minguy, H. Plaisance, J.-C. Galloo & R. Guillermo Ecole des Mines de Douai, Departement Chimie et Environnement, France 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
