Perceived indoor air quality and its relationship to air pollutants in French dwellings

摘要

Perception of indoor air quality (PIAQ) was evaluated in a nationwide survey of 567rnFrench dwellings, and this survey was combined with measurements of gaseous andrnparticulate matter (PM10 and PM2.5) indoor air pollutants and indoor climate parameters.rnThe perception was assessed on a nine-gradernscale by both the occupants of therndwellings and the inspectors who performed the measurements. The occupants perceivedrnthe air quality in their homes as more pleasant than the inspectors. The inspectorsrnperceived the air quality as more unpleasant in dwellings in which the residentsrnsmoked indoors. Significant associations between PIAQ and indoor air pollutant concentrationsrnwere observed for both the inspectors and, to a lesser extent, the occupants.rnIntroducing confounding parameters, such as building and personalrncharacteristics, into a multivariate model suppressed most of the observed bivariaterncorrelations and identified the tenure status of the occupants and their occupation asrnthe parameters that most influenced their PIAQ. For the inspectors, perceived air qualityrnwas affected by the presence of smokers, the season, the type of ventilation, retrofitting,rnand the concentrations of acetaldehyde and acrolein.
