Air Pollution History
The 19th century (1800’s) and the industrial revolution
Heavy burning of wood and coal
Caused disease and death
Thermal Inversion
Warm air from the south and cooler air from the north collide over the wasatch front.
Higher levels of souther warm air flows over the lower levels of northern cooler air, creating the inversion.
Traps pollutants beneath layers of warm and cool air so pollutant can’t rise and disperse
Exacerbated Diseases by Air Pollution
Asthma, chronic bronchitis, lung cancer, heart disorders
Chlorofluorocarbons
Contain chlorine which is released in the atmosphere, interacting with ozone to form oxygen which does not protect us from UV radiation.
Chemicals that precipitate acid in the atmosphere
