- Air Pollution is a common contributor to health issues that is typically more abundant in urban environments. In this week's lab exercise you will examine levels of air pollution in the Phoenix Metropolitan area. The measurable levels of different pollutants indicate an overall air quality index (AQI). Anthropogenic sources of pollution (Carbon monoxide, Ozone) are a major contributor to higher AQI values but particulate matter (PM-10) is also important in determining an AQI score. Choose all listed sources that would contribute to increased particulate matter (PM-10) levels. and EXPLAIN WHY YOU CHOOSE IT. DEFEND YOUR ANSWER choices: a.
