5.2. Dissolved Organic Carbon facilitated transport

Try these first

1. 1.

   What is dissolved organic carbon (DOC)?

   Hint

   Think about its role in aquatic systems.

2. 2.

   Define resuspension.

   Hint

   Consider what happens during a storm.

3. 3.

   What does DOC stand for?

   • Dissolved Organic Carbons
   • Dissolved Organic Compounds
   • Dissolved Organic Carbon

   Hint

   Remember the full term.

4. 4.

   True or False: Bioturbation can decrease the porosity of sediment.

   • True
   • False

   Hint

   Think about how worms interact with sediment.

5. 5.

   Discuss how fluctuating environmental conditions might affect DOC's ability to facilitate contaminant transport in various ecosystems.

   Hint

   Consider how each factor influences chemical interactions.

6. 6.

   Design an experiment to measure the impact of bioturbation on contaminant dispersion in sediment.

   Hint

   Think about how to measure changes in both setups effectively.
