Presentation Transcript

  1. Why CHEMISTRY? • Understand & Predict human exposure and health effects; • Understand & Predict fate & effects in environment; • Design control measures

  2. Name: Pyrene • Molecular weight: 202 • Boiling point: 404oC • Melting point: 156oC • Vapor pressure: 7.9x10-9 atm • Solubility: 0.135 mg/L • log Kow: 4.88 Solid at room temperature Not highly volatile Moderately soluble Hydrophobic – may bioaccumulate

  3. Where in the environment is it likely to be found; • What will be major route of human exposure; • Will it bioaccumulate? • Will it be persistent?

  4. Choose and design appropriate treatment; • Predict where compound will go in conventional treatment schemes; • Find “greener” alternatives;

  5. GREENER?
