1.1. Experimental Data on Dibenzofuran

Try these first

1. 1.

   What happens to the flux of dibenzofuran when soil dries?

   Hint

   Think about how moisture levels change.

2. 2.

   What is dibenzofuran?

   Hint

   Remember: it's a specific type of chemical.

3. 3.

   What is the effect of soil moisture on dibenzofuran flux?

   • Flux decreases with higher moisture
   • Flux increases with higher moisture
   • Flux remains the same

   Hint

   Consider how water affects chemical movement.

4. 4.

   Is the Thornwaite-Holzman equation useful for estimating dispersion parameters?

   • True
   • False

   Hint

   Think about the complexity involved in the movement of chemicals in air.

5. 5.

   How would you experimentally determine the flux of dibenzofuran in a given contaminated zone? Describe required techniques and data needed.

   Hint

   Think about measuring both concentration and moisture levels.

6. 6.

   Discuss potential errors in measuring dibenzofuran flux due to turbulence. What factors could influence accuracy?

   Hint

   Consider conditions that make measurements less precise.
