3. Gaussian Dispersion Model - Example, Additional topics
The chapter covers the Gaussian dispersion model to estimate the concentration of pollutants emitted from various sources. It discusses the application of this model in real-world scenarios, emphasizing the significance of receptor locations in assessing air quality. Further, it highlights the importance of planning for emergency responses and the strategic siting of industrial sources to minimize public exposure to pollution.

What we have learnt
- The Gaussian dispersion model helps estimate pollutant concentrations at specified locations based on emissions and meteorological data.
- Stability classes and plume rise significantly influence the dispersion of pollutants in the atmosphere.
- Planning for industrial site locations and emergency responses can mitigate public health risks associated with air pollution.
Key Concepts
- -- Gaussian Dispersion Model
- A mathematical model used to predict the concentration of pollutants in the atmosphere from point sources based on emission rates and environmental conditions.
- -- Stability Class
- A categorization that defines atmospheric stability conditions, impacting the dispersion of pollutants; typically classified as A to F depending on the thermal stability of the air.
- -- Isopleth
- A contour line on a map representing areas of equal pollutant concentration, derived from dispersion modeling data.
