As people spend a considerable amount of time indoors, either at work or at home, indoor air quality plays a significant part in their general state of health. This is particularly so for children, elderly people and other vulnerable groups.
The WHO guidelines for indoor air quality, developed under the coordination of WHO/Europe, address three groups of issues:
These three categories were recommended by experts in 2006 in view of their public health relevance. Experts also discussed the role of WHO guidelines in reducing the health risks due to indoor air pollution, and recommended scope and format of the guidelines.
WHO/Europe published the guidelines for dampness and mould in 2009, those on selected pollutants in 2010 and expects to issue those on indoor combustion of fuels in 2011.
