The quality of atmospheric air can be seen as a major problem nowadays, since it has been deteriorating every day and characterizing as one of the most serious threats to the life quality of human beings. In this work, the air quality in the Interlagos and Ponte dos Remédios region is defined in terms of particulate matter concentration with a diameter smaller than 10μm (PM10). The PM10 concentration in the air is the final result of complex processes, which are due to several factors, that include not only the emission by the sources, but also their physical (dispersion) and chemical interactions (reactions). The variability of dispersion is directly connected to topography and weather conditions. In this context, the objective of this work was to analyze the relationship between meteorological variables (wind speed, relative humidity, temperature and precipitation.) and PM10 concentration in the extreme months of 2014 (highest and lowest concentrations) using the multiple linear regression model. The results showed that the MP10 concentration is correlated with the wind speed and relative humidity in the two localities under analysis. In addition, most of the unfavorable days to the PM10 dispersion in 2014 occurred in June and August. Months that focused the highest concentrations of PM10 in the two localities.
