BACKGROUND In a previous study it has been shown that mean population perception of air pollution correlates well with physical measures of actual air pollution and could be used as a measure of exposure to air pollution, at least for those forms of pollution perceptible to humans. However, for such a measure to be valid researchers would need to be confident that it was not strongly biased by ...

One explanation is that smoking rates are higher in urban areas, although it is not clear whether the variations in smoking behaviour fully account for the observed urban/rural gradient in lung cancer incidence. Indeed, some studies have demonstrated an e...
