Abstract:

Ambient air pollution is one of the biggest threats to human health over the whole world. One of the most important forms of ambient air pollution is particulate matter (PM); within this, the PM2,5 and PM10 concentrations are analysed. The concentrations of PM are impacted by meteorological conditions as well as local variations. This research aims to look at to what extent weather conditions and spatial distribution affect the PM10 and PM2,5 concentrations, within the city of Vienna, Austria. The results show that certain weather conditions like wind direction, wind speed, cyclonic conditions, precipitation, and humidity have a significant impact on the PM10 and PM2,5 concentrations. Furthermore, analysis has been done on the effects of spatial distribution on the PM concentrations; the results show differences in PM concentrations near green spaces compared to more dense urban areas with busy roads and built-up areas. These mobile measurements were done in the winter months and the summer months to see if there is a difference in the PM concentrations with the seasons. The mobile measurements indicate that the location of the measurements is highly correlated to the PM concentrations. The results show that the combination of meteorological conditions and the spatial distribution of PM affects the concentrations significantly. When looking at the PM10 concentrations, the results show that wind direction, cyclonic or anticyclonic conditions at 925hPa and at 500hPa and humidity conditions have a significant impact on the PM10 concentrations. When looking at the PM2,5 concentrations the results show only wind direction and humidity conditions have a significant impact on the concentrations. The results show that the PM10 and PM2,5 concentrations are impacted by the characteristics of their surroundings.
