20.500.12556/DKUM-89926 Porazdelitev črnega ogljika glede na oddaljenost od ceste magistrsko delo The distribution of black carbon with respect to distance from the road V našem magistrskem delu smo proučevali problematiko črnega ogljika, pomembnega onesnaževalca zraka, ki ga večinoma izločajo vozila z notranjim izgorevanjem in procesi gorenja biomase. Osredotočili smo se na merjenje njegovih koncentracij ob prometni cesti kategorije R1, kjer so bile le-te najvišje. Izvajali smo meritve na razdaljah 0, 20, 50 in 100 metrov od ceste. Ugotovili smo, da so koncentracije črnega ogljika najvišje tik ob cesti, nato pa postopoma padajo s povečevanjem razdalje od nje. Kljub temu smo opazili neobičajno visoke koncentracije na 100 metrih, ki so v nekaterih primerih presegle celo izhodiščne vrednosti. Opravili smo tudi štetje prometa, kar nam je omogočilo boljše razumevanje vpliva prometnega pretoka na koncentracije črnega ogljika. Rezultati kažejo na visoke koncentracije ob cestah, kar poudarja pomemben vpliv prometa na onesnaženje zraka. Koncentracije na 100 metrih od ceste so nekoliko presenetljive, kar nakazuje kompleksnost dinamike črnega ogljika v okolju, kjer lahko vplivajo različni dejavniki, kot so vremenski pogoji, smer vetra, topografske značilnosti ter vsebnost vozil. Pomembno je nadaljevati s celovitimi raziskavami, ki bodo prispevale k boljšemu razumevanju vpliva prometa na kakovost zraka in razvoju ustreznih ukrepov za zmanjšanje emisij črnega ogljika ter izboljšanje kakovosti okolja. In our master's thesis, we investigated the issue of black carbon, a major air pollutant mainly emitted by internal combustion vehicles and biomass burning processes. We concentrated on measuring its concentrations along a primary road (category R1), where levels were highest near the road. Measurements were taken at distances of 0, 20, 50, and 100 meters from the road. Our findings showed that black carbon concentrations peaked right next to the road and gradually decreased with distance. However, we noted unexpectedly high concentrations at 100 meters, sometimes even surpassing the baseline values. Traffic counts were also conducted to better understand the effect of traffic flow on black carbon levels. The results revealed high concentrations near roads, underscoring the significant impact of traffic on air pollution. The elevated concentrations at 100 meters were surprising, indicating the complexity of black carbon behavior in the environment, influenced by factors such as weather conditions, wind direction, topography, and vehicle content. Ongoing comprehensive research is crucial for better understanding the impact of traffic on air quality and developing effective measures to reduce black carbon emissions and improve environmental quality. črni ogljik onesnaženje meritve črnega ogljika porazdelitev črnega ogljika Celjska kotlina black carbon pollution black carbon measurements distribution of black carbon Celje basin true true false [L.
