Measurements and model simulations of air pollution in urban agglomerations and industrial places have shown high concentrations of gaseous and particulate matter pollutants such as photochemical gaseous pollutants and particulate matter.The world's urban population increased over the past 50 years with an average rate of 2.7% year~(-1).By contrast,the total world population increased with an average rate of only 1.8% year~(-1).This illustrates the increasing global importance of urban agglomerations and industrial activities,thus their growing significance for the world's air quality and climate problems.Air quality degradation in urban agglomerations and industrial sites has significant effects to human health leading to increased morbidity and mortality,to urban and regional air quality degradation and consequently to the earth's climate.
