Abstract: Uberlandia is an important city of the Brazil central region. In this work, the Total Suspended Particles (TSP) and particles smaller than 10 μm (PM₁₀) were sampled from 2003 to 2006. The Geostatistical technique was used to evaluate the temporal dependence and the time-series analysis with 2004 and 2005 data was used to predict 2006 values. The selection of the best model was conducted using Akaike|s information criterion. The obtained results show that the PM₁₀ and TSP series present trend and seasonal components. The SARIMA (0, 2, 1) (0, 2, 1) was the tested model that presented the best predictions.

Keywords: particulate matter; air pollution; time series; PM10; Brazil; total suspended particles.
