5. Contaminated Sediments Remediation Options

Try these first

1. 1.

   What is bioturbation?

   Hint

   Think about how animals interact with soil.

2. 2.

   Define advection.

   Hint

   Consider how a river carries debris.

3. 3.

   What is the main role of bioturbation in sediments?

   • It prevents pollution.
   • It redistributes contaminants.
   • It only cleans sediments.

   Hint

   Think about how organisms impact soil.

4. 4.

   True or False: Advection is the process of spreading pollutants from high to low concentration.

   • True
   • False

   Hint

   Remember the definitions of advection and diffusion.

5. 5.

   Propose a remediation plan for a contaminated sediment site near an urban area. What factors would you consider in your plan?

   Hint

   Think about the environmental and social contexts of the area.

6. 6.

   Analyze how changed bioturbation levels due to habitat loss would impact sediment remediation strategies.

   Hint

   Reflect on the role of living organisms in sediment health.
