During the national survey conducted by the French Observatory of Indoor Air Quality in 2003-2005 in a representative sample of the housing stock, subjects completed daily diaries reporting for every 10-minute interval their domestic activities and the products used for them. The analysis of these diaries yields percentages of domestic activities and product use among i) individuals and ii) dwellings where at least one occupant performed the activity or used the product. Moreover, this analysis provides for the individuals concerned, the daily frequency and cumulative duration of each activity and product use. These results are consistent with those of the time use survey conducted by the National Institute of Statistics and Economic Studies in 2009-2010, for the metropolitan population and for the activities common to both studies. The percentage of use of the products seems to be underestimated, while the individual durations of use are consistent with the data commonly used for consumer exposure assessment in Europe. These results provide exposure data specific to the French population, useful for risk assessment linked to domestic activities and residential use of consumer products.
