Meta studies of air pollution epidemiology have resulted in the use of transferable dose-response coefficients whereby the statistical relationship between air pollution and human health is applied outside the countries of the original studies. The aim is to predict changes in premature mortality and morbidity. Some studies then apply economic valuations in order to see if health damage from air pollution should be treated as a priority concern in the countries to which the coefficients are applied. Preliminary work suggests that some forms of air pollution, notably inhalable particulate matter and ambient lead, are serious matters for concern in the developing world.
