Clean Air Act
• Since the time of the Industrial Revolution, air pollution has been a major public health problem. In 1948, in Donora, Pennsylvania, an air pollution episode resulted in the deaths of nineteen people in a community of 14,000; 43 percent of the population were adversely effected. The cause was industrial emissions of combustion products combined with a thermal inversion. Today, air pollution still causes extensive rates of morbidity and mortality, and it poses a particular risk for children and those with chronic lung disease. Air pollution is a complex mixture of substances discharged into the air in a myriad of ways.
