Oro taršos kietosiomis dalelėmis tyrimas Naujojoje Akmenėje ; The Study of Air Pollution by Particulate Matter in New Akmenė
Modern living and working conditions have changed over the past decades, and rapid technological development has led people to spend most of their lives indoors. The aim of the research is to determine the contamination of public spaces in the city of Naujoji Akmenė with solid and biological particles and to assess the air quality of these premises. The particulate concentration of 15 different air sizes was measured with a FLUKE 983 dust gauge. The results are expressed in μg / m3. Microscopic fungi in indoor air were collected by a cyclonic air trap and grown on potato dextrose agar medium. The microscopic fungus species were identified by a light microscope, the final results are given in colony forming units of 1 m3 air (CFU / m3). Studies have shown that the World Health Organization recommended limit values for PM2.5 (25μm / m 3 ) and PM10 (40 μm / m3) were exceeded in VDA child occupancy group indoor air (KD 0.5 and 1.0 μm). Attention should be paid to indoor ventilation systems in event halls, because after the festive event VDŽ-2 air was polluted with PM particles: from 2.0 μm 25 ± 2 μm / m3 to 196 ± 52 μm / m3. Concentrations in excess of WHO recommendations have also been identified in the library's occupation department: 5.0 and 1.0 μm concentrations were about 50 μm / m3. Analysis of indoor air pollution by microscopic fungi showed that there is no correlation between solid particles and microscopic fungi. However, there was a tendency for the construction and agricultural trade hall air to be polluted with 5.0 μm particles (45 μm / m3) and microscopic fungi - 1649 ± 253 CFU / m3 (WHO recommendation 500 CFU / m3) Dust analysis showed that a very topical issue is cleaning the air vents. In four of the nine air vents tested, the microscopic fungus content was ≤100 units / plate. In the air and on the dust, allergic reactions and microscopic fungi generating mycotoxins - Penicilium spp., Aspergillus spp., Cladosporium spp.
