    Many studies have shown a close relationship between air pollution by particulate matter (PM10) and deterioration of human health. Because the particulate matter can contain a variety of chemical and biological components, in addition to its size directly influence the public health issue. Therefore, knowledge of particulate matter levels, as well as their composition, is important for preventive actions. In view of this problem, the study of the particulate material in the city of Catalão - GO was carried out in two different places (UFG-RC and Centro), and for the PM10 collection the AGV PM10 was used. We studied 30 samples collected between August 2017 and March 2018, in periods of 24 hours at a frequency of 6 days. The concentrations of PM10 of both sites did not exceed the established of 150 μg.m3 of PM10 daily, according to Resolution 003/90 of CONAMA. However, for the WHO recommendation setting 50 μg.m3 , there was extrapolation in the dry period for samples of equipment located in the city center. A correlation was observed between the meteorological conditions and the concentrations of the particulate material, because, as there was an increase in the pressure, temperature and wind speed, there was an increase in the PM and as the humidity increased, the concentration decreased. We found 13 elements in the filters through the use of EDXRF, which in turn, were associated with vehicular emissions and resuspension of the study environment. The cytotoxic study of the filters from both sites was performed, and it was possible to observe that there are microorganisms associated with the PM, but in the tests performed they were not harmful (toxic) to the microorganisms studied, since there was no halo of inhibition and there was growth of microorganisms. Therefore, the results showed that the concentration of PM10 for the city of Catalão - GO is in accordance with Brazilian legislation, thus, it presents good air quality. However, this particulate matter is small enough to penetrate the body and is harmful to human health because it has metals and microorganisms that may have a cumulative effect on the body.
