There is growing recognition that air pollution has deleterious effects on health, but emphasis has largely been concerned with outdoor pollutants. Most of the population, however, spends the majority of their time indoors. Studies in ALSPAC homes have shown that the levels of a number of different pollutants can be influenced by factors such as new furnishings, type of heating and cooking as well as chemicals used such as aerosols and so-called air fresheners. However the way in which different outcomes are affected, the combinations of pollutants that may be harmful, the genetic composition of the most susceptible individuals and the consequences on the next generation(s) have yet to be identified.

This project is devised to set the scene by identifying the different variables available for in-depth studies by experts in different fields.
