“What is air pollution control all about?”  We should also answer the question, “Why care about air pollution control?”  This is an important question!  We will be answering this question throughout this course, but the short answer is that air pollution causes significant adverse health effects, including early death (!) and excess disease and impacts the environment (reduced visibility, climate change, ozone depletion, acid rain) and a very important way to reduce air pollution is to USE air pollution controls to keep the pollutant emissions to a minimum.  We will investigate the major types of air pollution including particulate matter, volatile organic compounds, sulfur oxides, and nitrogen oxides.  We will discus background topics such as health effects, aesthetic effects (acid rain, visibility), laws and regulations, meteorology, atmospheric chemistry and pollutant transport in the atmosphere.
