Indoor Air Quality

We spend 85% of our time (or more for certain susceptible populations such as young children and the elderly) in closed environments in which we may be exposed to multiple pollutants.

These pollutants are emitted by the building itself, its equipment or its decoration (wall coverings, flooring, furniture, etc.). They also come from the immediate outdoor environment and the activities of the occupants.  See the Agency’s work on this issue.
