EESA10H3 Chapter Notes - Chapter 2: Bronchoconstriction, Particulates, Asbestosis
After these epidemics, scientists and governments paid increased attention to the health effects of air pollution: i. e. identifying specific pollutant sources and their transport in atmosphere, elucidating exposure response relationships, and developing air pollution control. Despite efforts, air pollution still occurs today because: of changes in atmosphere resulting in the transportation, dilution, precipitation, and transformation of contaminants, primary emissions of heavy metals (i. e. cadmium and lead), sulfur and nitrogen oxides, carbon monoxide, and respirable particulates severely polluting cities and towns in asia, africa, latin america, and eastern. Sources: coal and oil power plants, oil refineries, smelters, stoves burning wood, coal, and kerosene, motor vehicle emissions, fossil fuel burning, automobile emissions, fossil fuel power plants, oil refineries, automobile emissions, ozone generators, aircraft cabins, diesel exhaust, cigarette smoke, stove smoke, natural, asbestos mines and mills. Insulation: building materials, copper smelters, cigarette smoke, pollen, animal dander, house dust.
