Document Summary
Air pollution emergencies were caused by ait stagnation, which resulted in greatly increased concentrations of atmospheric pollutants, especially sulphur dioxide and suspended particulates. Asia, africa, latin america, and eastern europe: relationship between air pollution and wealth; poorer countries (relying heavily on coal) had significantly higher levels of total suspended particulates (tsps) than wealthier nations. In nations that have reduced the primary emissions from heavy industry, power plants, and automobiles, new problems have arisen from pollution by newer industries and from air pollution caused by secondary formation of acids and ozone. The resulting high levels of air pollution (including indoor air pollution) contribute heavily to the high mortality rates observed for acute respiratory disease in children under the age of 5 in many developing countries. Defining adverse health effects: adverse health effect; any effect that results in altered structure or impaired function that represents the beginning of a sequence of events leading to altered structure or function.
