Description In the present paper, long-memory in air pollutant concentrations is reviewed and outcome of the past studies is
analyzed to provide the possible mechanism behind temporal evolution of air pollutant concentrations. It is observed
that almost all the studies showair pollutant concentrations over time possess persistence up to a certain
limit. Self-organized criticality of air pollution, multiplicative process of pollutant concentrations, and uniformity
in emission sources leading to self-organized criticality are fewof the phenomena behind the persistent property
of air pollutant concentrations. The self-organized criticality of air pollution is linked to atmosphere's selfcleansing
mechanism. This demonstrates that inspite of increasing anthropogenic emissions, self-organized criticality
of air pollution is sustained and has lowinfluence of human interventions. In the future, this property may,
however, be perturbed due to continuous air pollution emissions, which may influence the accuracy in
predictions.
