Abstract

Indoor and outdoor aldehyde concentrations in a medium-sized French town R. Meininghaus*, E. Basthr, S. Bourdef, A. Cicolella\ D. Granier* & N. Gonzalez-Flesca* France Abstract Aldehydes are air pollutants with the potential to act as strong sensory irritants. Outdoors, these compounds play a part in the complex system of photochemical atmospheric reactions, and they are directly released by traffic and other combustion sources. Indoors, numerous emission sources have been identified, for example tobacco smoking or furniture. The objective of the present study was to measure average concentrations of selected aldehydes in typical urban environments. A pilot study was carried out in Nancy, a medium-sized town in the Northeast of France. Outdoor concentrations of seven aldehydes were measured by exposing passive samplers for two periods each lasting five days. 30 samplers were installed at background sites and at sites frequently visited by people. Moreover, 20 volun
