The present study aims to track the influence of location and climate dynamics on the distribution and relationship of fine particulate matter (FPM) and airborne microorganisms. Hot spots, green urban areas and green peripheral areas in five Bulgarian cities with different climatic specificities were studied - Sofia, Plovdiv, Stara Zagora and Burga. The samples were collected using an air spinner. The total number of microorganisms was established, as well as the percentage of individual microbiological groups rel...

Air pollution is a major problem related to human health and the protection and quality of the environment. Increasingly emphasis is placed on the problems associated with fine dust particles, without paying enough attention to the potential problems associated with the increase of microorganisms in the ground air layer. The present pilot study aims to establish the dynamics in the number of microorganisms at different height in the ground air. Six hot spots and six green zones were analyzed at a distance from the...
