EESA10H3 Chapter Notes - Chapter 2: Hemoglobin, Antimetabolite, Therapeutic Irrigation
Document Summary
Whole communities were engulfed in air pollutants resulting in serious illness and death among individuals with cardiopulmonary diseases. They were caused by air stagnation which resulted in increased concentrations of pollutants including sulfur dioxide and suspended particles. London was the worst case and mortality was due to bronchitis, pneumonia and acute exacerbation of underlying respiratory disease. Air pollution has no boundaries and contaminants are transported, diluted, precipitated and transformed. Primary emissions of sulfur dioxide, nitrogen oxides, and carbon monoxide are polluting cities and towns in asia, africa, and america. Relationship between air pollution and wealth: poorer countries had higher levels of total suspended particles than wealthier nations. Indoor air pollution contribute to the high mortality rates for acute respiratory disease. So2 produced by the combustion of sulfur contained in fossil fuels (coal and crude oil) Sources: electric power generating plants, oil refineries and smelters. Nations like china greatly depend on coal.
