1. Environmental Quality: Monitoring and Analysis

Try these first

1. 1.

   Define bioturbation.

   Hint

   Think of how worms affect the soil.

2. 2.

   What does advection refer to?

   Hint

   How does wind or water carry substances?

3. 3.

   What is bioturbation?

   • a) Movement of water
   • b) Mixing of sediments by organisms
   • c) Process of erosion

   Hint

   Think about worms and their activity in soil.

4. 4.

   True or False: Advection only occurs in water bodies.

   • True
   • False

   Hint

   Consider where air pollution comes from.

5. 5.

   Calculate the flux if 10 mg/L of a contaminant enters a closed system while 4 mg/L exits over an area of 2 m².

   Hint

   Remember the mass balance principle.

6. 6.

   Design an experiment to evaluate bioturbation's effect on sediment quality in a freshwater environment.

   Hint

   Include factors like water flow, organism types, and sediment types.
