assessing health risks of indoor air pollution.

Indoor exposure to air pollutants may occur in both private and public indoor environments such as homes, offices, schools and transport systems.
Some indoor air pollutants come from the outside, but most are released inside the building, for example when cleaning or when burning fuel for cooking and heating. Furniture and construction materials can also emit pollutants. Dampness and lack of ventilation may further increase indoor air pollution.
Because indoor air can contain a mixture of many different pollutants, it is very difficult to assess the associated risks to health. Moreover, there is no such thing as a “typical indoor environment”.
This opinion considers how health risks of indoor air pollutants are currently evaluated and how they should be assessed in the future, taking into account simultaneous exposure to multiple pollutants and particularly vulnerable groups of population such as children, pregnant women and elderly people.
