The seasonality of the drought period in the Brazilian Midwest presents peculiarities regarding the potential of damage to the environment and human health through atmospheric pollution. This paper aims to analyze the concentrations of particulate matter (MP1, MP2.5 and MP10) in the urban area of the municipality of Rondonópolis (MT), relating to the meteorological variables and hot flashes, from August to September 2017. Weather data comes from the National Institute of Meteorology (INMET). The data from heat sources were obtained from the National Institute for Space Research (INPE). In the field, air pollution data were collected using the measurement of particulate matter - MP, MP1, MP2.5 and MP10, by means of the Aeroqual model AQM10 device installed at the Municipal Secretariat of the Environment (SEMA). Statistical analysis was used as the 5% significance Kendall correlation, which was later adjusted to the Gamma regression model, belonging to the Generalized Linear Models (MLG) class, with a significance level of 5% (p <0, 05). Kernel density was applied, and a map of heat foci was created. Climatic variables, temperature, relative humidity and precipitation influence the concentrations of particulate matter (MP₁, MP₂, ₅ and MP₁₀) in the atmosphere of Rondonópolis, southern Mato Grosso region.
