SALINI CALDERON, Giovanni Angelo  e  MEDINA MITMA, Evelin Jhovana. STUDY ON THE TEMPORAL DYNAMICS OF COARSE PARTICULATE MATTER (PM ₁₀ ) CONCENTRATIONS EMITTED AT COCHABAMBA, BOLIVIA. Rev. Int. Contam. Ambient [online]. 2017, vol.33, n.3, pp.437-448. ISSN 0188-4999.  https://doi.org/10.20937/rica.2017.33.03.07.

This paper presents a study of PM10 time series showing the poor air quality at Cochabamba city through statistical tools used in studies on nonlinear dynamics. The daily average of PM10 follows patterns similar to large cities with high of environmental pollution patterns. One of the parameters resulted from the same order and characteristic as those presented in similar studies on the chaos in pollution variables such as ozone, PM2.5, CO, demonstrating the chaotic origin of these data. Our results contribute to the literature since they introduce a more detailed methodological analysis of the nonlinear nature of PM10 concentration.

Palavras-chave : air pollution; nonlinear dynamics; air quality; nonlinear time series; chaos.
