2. Transport of Pollutants – Dispersion

Try these first

1. 1.

   What causes unstable atmospheric conditions?

   Hint

   Think about the role of wind in this context.

2. 2.

   Define mixing height.

   Hint

   Focus on the equilibrium between air parcels and the environment.

3. 3.

   What condition leads to rapid dispersion of pollutants?

   • Stable
   • Unstable
   • Neutral

   Hint

   Consider what happens during windy weather.

4. 4.

   True or False: Mixing height is the same as the height a pollutant can reach indefinitely.

   • True
   • False

   Hint

   Think about scenarios when pollutants can’t rise freely.

5. 5.

   Given a scenario with fluctuating environmental lapse rates, how would you predict pollutant dispersion over a day? Describe how you would approach this problem.

   Hint

   Think about the how changes in temperature at different times affect dispersion.

6. 6.

   Consider a city where thermal inversions frequently occur. Discuss the potential long-term environmental and health impacts.

   Hint

   Evaluate sustained exposure's effects on both human health and local wildlife.
