Lecture 18 - Environmental Transport
See Lecture Schedule for
Delivery Date
Learning Objectives
- Understand the spatial and temporal diversity of
toxicological and contamination events.
- Describe the linkage between natural forces and
chemodynamics of contaminants.
- List important zones of impact and understand the
relationships of human activity and potential for chemical
release and contamination.
- Understand the relationship of transport and specific
chemical processes of contaminants.
- Explore, as an example, the fundamental processes of
dissimilatory iron reducing bacteria and their role in
contaminant transformation and transport.
- Develop knowledge of groundwater movement and processes
related to contamination.
- Understand the interaction of non-aqueous phase liquids
with groundwater.
- Gain an introductory understanding of atmospheric
transport of contamination using acid rain as an example.
