Outline of air pollution dispersion

Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, and the natural or built environment.

Air pollution dispersion has become the focus of environmental conservationists and governmental environmental protection agencies (local, state, province and national) of many countries (which have adopted and used much of the terminology of this field in their laws and regulations) regarding air pollution control.

Plumes are of considerable importance in the atmospheric dispersion modelling of air pollution.

[10] Such that, for flows where the cloud of pollutant is smaller than the largest eddies present, there will be mixing.

Table 1: The Pasquill stability classes Table 2: Meteorological conditions that define the Pasquill stability classes Incoming solar radiation is based on the following: strong (> 700 W m−2), moderate (350–700 W m−2), slight (< 350 W m−2)[13] The stability class can be defined also by using the Advanced air pollution dispersion models – they do not categorize atmospheric turbulence by using the simple meteorological parameters commonly used in defining the six Pasquill classes as shown in Table 2 above.
