Jeu de données relatif à la deuxième campagne nationale de mesures de la qualité de l'air intérieur dans les logements français (CNL2)

The Indoor Environment Quality Observatory (OQEI) presents the results of the second national campaign on indoor air quality in homes across France. This campaign covers the period from November 2020 to February 2023. It combines one-week air quality measurements taken in participants' homes with a survey on housing characteristics, household composition, and existing equipment. The survey also includes the frequency of domestic activities and occupants’ perceptions of their comfort. A self-administered questionnaire on respiratory and allergic health, collected for analysis by Santé publique France, concludes the study.

The measured parameters were selected based on a health prioritization updated according to their toxicity and prevalence, as well as their impact on comfort. Over 170 pollutants and parameters were measured in the indoor air of homes during this national campaign.

At the end of the fieldwork, 571 homes had been surveyed, and a total of 1,516 individuals responded to the questionnaire. The surveyed homes are located in 321 municipalities across 84 departments. A weighting system was developed to extrapolate the observed results to the scale of the 29.7 million primary residences in mainland France.
