19.Air Pollution and Climate Change
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 earth's surface - 0.5 m, 1 m and 1.5 m, respectively. An “open air” method was used. Samples were taken simultaneously at all points. Basic meteorological parameters were recorded - air temperature, air humidity, wind direction and speed, solar radiation. The amounts of bacteria, microscopic fungi and actinomycetes were recorded. The total microbial number for each of the points per 1 cubic meter of air was calculated. The data show a different scatter of the total number of microorganisms depending on the height. The number of airborne microorganisms is higher in hot spots. Certain differences in the dominant microbial groups were reported depending on the altitude and area considered. The data suggest a direct link, with increased levels of the airborne microbial community and vehicular traffic intensity in hotspots.
