CHEM 2505

A study of chemical reactions in the environment. Topics include composition of the atmosphere, photochemical reactions in the stratsphere (ozone production and loss) and troposphere (production of smog), simple models to describe room air quality, transfer of gases across interfaces, chemistry of natural waters (hardness, alkalinity), treatment of drinking water (chlorination and aeration/coagulation) and waste water (primary, secondary and tertiary treatments). Chemicals to be discussed include formaldehyde, chlorinated hydrocarbons, pesticides, PAHs, and heavy metals.
