Air Pollution Dispersion
- Air pollution dispersion is often
studied with simple models called box models.

- The ventilation factor gives us a
way of relating the pollution concentration to
the parameters that control dispersion of the
pollution in the local environment.
- Basically, increasing either the mixing
height or the wind
speed increases the effective volume in which
pollutants are allowed to mix.
- The larger the volume, the lower
the pollution concentration
