1.4. Mapping and Visualization of Pollutant Concentration

Try these first

1. 1.

   Define the Gaussian Dispersion Model.

   Hint

   Think about how air pollution spreads from sources.

2. 2.

   What are contour maps used for?

   Hint

   Consider 'isopleths' as lines of equal value.

3. 3.

   What is the Gaussian Dispersion Model primarily used for?

   • To measure sound levels
   • To predict pollutant dispersion
   • To calculate population density

   Hint

   Focus on air pollutants.

4. 4.

   True or False: Contour maps can represent geographic areas of even concentrations.

   • True
   • False

   Hint

   Think about how maps represent topography.

5. 5.

   Using the Gaussian model, calculate the estimated concentration of sulfur dioxide from a stack at different distances (50m, 500m) under varying stability classes (C and D).

   Hint

   Refer to the stability class chart for sigma values.

6. 6.

   Describe how you would model a scenario where two factories are emitting pollutants simultaneously next to a residential area. What factors would you consider?

   Hint

   Focus on applying the superposition principle of dispersion.
