The present study aims to track the quantity and distribution of microorganisms in the ground air in "hot points" and park areas of the territory of the city of Sofia. For this purpose, 6 "hot points" were selected, on the territory of boulevards and intersections, and six in the park areas of the capital. The study was carried out using the "Open air" method on suitable solid nutrient media. Each measurement was performed in five replicates. The total microbial number was determined, as well as the amount of the main microbiological groups. The potential presence of streptococci and staphylococci was reported. The data show several times increased levels of the total microflora in the hot spots compared to the green areas. There is also a difference in the percentage participation of the different microbiological groups in the two types of areas studied. In the hot points, fungi represent the main group of microorganisms, followed by bacteria. In green areas, bacteria represent the main group of microorganisms.
