This lab will be used for measuring physico-chemical properties of organic compounds (e.g., aqueous solubility, Henry's law constants, and octanol-water partition coefficients), kinetics of transformation of organic xenobiotic compounds under environmentally-relevant conditions, and sorption rates and equilibrium concentrations. Concentrations of xenobiotic compounds in natural samples from air, water, and sediment will also be analyzed. The measurements are used in conjunction with computational chemistry to predict, based on chemical structure, how these chemicals are transported, transformed, and mineralized in the environment. The general goal of the research conducted is to further the ability to predict xenobiotic compound fate and transport based on molecular structure. The knowledge obtained in this laboratory benefits society by elucidating where these chemicals, which are carcinogens and teratogens, end up in the environment, and pathways and rates at which they are transformed and mineralized. This lab is closely linked with the Environmental Chemistry Research Laboratory (rm 835) which will serve as a preparation laboratory for analytical determinations of organic compounds in liquid and solid phases.
