Pick a commonly used and potentially harmful chemical and do some research to learn about (a) what it is used for and how widely it is used, (b) its potential harm, (c) the scientific evidence for such claims, and (d) proposed solutions for dealing with this threat. Pick a study area, such as your dorm or apartment building, your block, or your city. In this area, try to determine the level of presence of the chemical you are studying. You could do this by finding four or five examples of items or locations containing the chemical and then estimating the total amount based on your sample. Write a report summarizing your findings.
