6. Conclusion and Future Directions

Try these first

1. 1.

   What are the two main mechanisms of contaminant transport in sediments?

   Hint

   Think about how chemicals move through solids and liquids.

2. 2.

   State one effect of sediment contamination on aquatic ecosystems.

   Hint

   Consider the relationships between species.

3. 3.

   What is the process by which sediment particles enter the water column called?

   • Diffusion
   • Resuspension
   • Adsorption

   Hint

   Think about disturbances that release sediment into the water.

4. 4.

   True or False: Sediments can only act as sinks for contaminants.

   • True
   • False

   Hint

   Consider the dual role of sediments in pollution.

5. 5.

   Analyze a scenario where heavy rains cause increased turbidity in a river. What impacts could this have on native fish populations?

   Hint

   Consider the relationship between water quality and fish health.

6. 6.

   Design a strategy to monitor sediment contamination over time in a river ecosystem. What factors would you consider?

   Hint

   Think about multi-faceted monitoring techniques.
