Lecture 18 - Environmental Transport

See Lecture Schedule for Delivery Date

Learning Objectives

  1. Understand the spatial and temporal diversity of toxicological and contamination events.
  2. Describe the linkage between natural forces and chemodynamics of contaminants.
  3. List important zones of impact and understand the relationships of human activity and potential for chemical release and contamination.
  4. Understand the relationship of transport and specific chemical processes of contaminants.
  5. Explore, as an example, the fundamental processes of dissimilatory iron reducing bacteria and their role in contaminant transformation and transport.
  6. Develop knowledge of groundwater movement and processes related to contamination.
  7. Understand the interaction of non-aqueous phase liquids with groundwater.
  8. Gain an introductory understanding of atmospheric transport of contamination using acid rain as an example.
