The present work had the objective of quantifying the PM10e, black carbon elemental carbon in the fine and coarse fractions, and verify through canonical analysis relations with the meteorological variables and heat sources. Sampling was carried out in the state of Mato Grosso from October to October 2004. The PM10 was continuously collected with the Thin and Fine Particulate Sampler which contained filters that separated material within a coarse fraction (2.5 <of <10 mm) and other (<2.5 mm), with a collection time of 48 and 72 hours. The analytical techniques employed for these analyzes were Gravimetry and Reflectance. The mean PM10 concentration was 20.6 μg.m-3, 62.2% of which was coarse particulate and only 37.8% of fine particulate. The fine black carbon had an amplitude of 0.3 to 4.2 μg.m-3. The result of the canonical correlation analysis showed that 42% and 61% of the changes in the respective fine and coarse particulate fractions are explained by the meteorological variables and heat sources. No significant relationship was detected with heat pockets.
