Document Summary
As a result of epidiemics, scientisits increased attention to the health effects of air pollution- identifiying specific pollutant sources and their transport in the atmosphere, elucidating exposure-response relationships. These crisis have several aspects: first since the atmosphere is dynamic and always changing, contaminants are transported, diluted precipitated and transformed. Second, the primary emission of sulphur oxides, nitrogen oxides, carbon monoxide, resporable particulates and metals are severely polluting cities and twon in asia, africa and latin eastern europe. Poor countries had higher level of total suspended particulates then wealthier countires. Third in nations, that have reduced the primary emissions from heavy industry, power plants and automobiles, new problems have arisen from air pollution contribute to heavily to the high mortality rates observed from acute respiratory disease. Any effect that results in altered structure or impaired function or that represents the beginning of a sequence of events leading to altered structure or function is considered an adverse health effect .
