1.6. Gaussian Dispersion Model Parameters

Try these first

1. 1.

   What is the definition of an emission rate?

   Hint

   Think about emissions in terms of quantity and time.

2. 2.

   What does an emission factor help to determine?

   Hint

   Consider how one could assess emissions from specific activities.

3. 3.

   What is an emission factor?

   • A measure of air quality
   • A coefficient for estimating emissions
   • The total emissions produced

   Hint

   Think about how we quantify pollutants.

4. 4.

   True or False: Fugitive emissions are planned releases of pollutants.

   • True
   • False

   Hint

   Consider the nature of the term 'fugitive'.

5. 5.

   Develop a dispersion model that incorporates both plume reflection and fugitive emissions for a manufacturing facility. Consider the types of pollutants emitted.

   Hint

   Consider how to estimate both known and unknown emissions.

6. 6.

   Examine how seasonal changes might affect the emission factors for a coal power plant and discuss strategies for compensating in models.

   Hint

   Think about how combustion and emissions might change with differing fuel types and weather patterns.
