title: Measurement of background urban nitrogen dioxide pollution levels with passive samplers in Montpellier, France.
abstract: Background nitrogen dioxide (NO2) pollution levels in Montpellier were measured in the context of an assessment operation carried out by the local monitoring network (AMPADI-LR), using Palmes passive samplers. The equipment was validated by continuous measurement with automatic chemiluminescence analyzers. Measurements from representative background pollution sites and the ensuing cartographic representation provide information about local pollution data, a description of seasonal evolution and an assessment of the influence of various sources. The study may be used to define parameters for establishing an exposure index, taking into account roads with heavy traffic, which affects the distribution of NO2 over Montpellier, and meteorological factors. This is a pilot study which will subsequently be used for a more precise assessment measuring the personal exposure of inhabitants, for the purposes of a study on effects on health.
