Abstract: Abstract It is shown that distribution of PM2.5 concentration recorded by eight air quality monitoring stations during 2021, covering a large part of the Santiago metropolitan region of Chile, can be explained by a q-Weibull function, which has been related in some papers to complex and non-equilibrium statistical systems. It was found that this function has an excellent fit performance on non-filtered data, which cannot be reached by other physical-statistical functions widely used to modeling air pollution distribution in the literature. Finally, relevant interpretations from the fit parameters are shown as well. Graphic Abstract
