This summer I was an intern with the Indiana Department of Environmental Management (IDEM). My department was air quality permitting. In this position, I was able to learn about the ways Indiana monitors and controls air pollution. I also read two books to compliment what I was learning as I worked, I read An Air That Kills by Jhon Reiuwerts, and Poison Spring by E.G Valliantos. In this paper I will first talk about my experience at IDEM then I will compare the US, Britain and Chinas using knowledge gained in school, at my internship, books, and other research. First, I will talk about pollution events that promoted response and then some of the policies that came from these events. Then I will compare the current systems in place to monitor air pollution in each nation. Then I will go over where the pollution comes from and what makes up that pollution. After that I will discuss some of the issues with current monitoring techniques.
