  • Nitrogen dioxide measurements in the Lower Seine region by the passive sampler method and analysis of the results with respect to the European Directive


The passive sampler method was used for a three-month period (April to June 1990) to map the nitrogen dioxide levels in the Lower Seine region. The average concentrations obtained during the campaign, compared with the values of the EC Directive, show that the risk of exceeding the Directive's limit value and the guideline value in the background sites (i.e. at least at 50 m of busy roads) is low. It seems advisable to set up two extra measuring stations: one in Rouen centre and one in Le Havre, both traffic survey oriented. There seem to be enough stations for the survey of industrial emissions.
