Palas® experts have published an article titled “Impact of ambient air filters on PM concentration levels at an urban traffic hotspot” in the journal Atmospheric Pollution Research by specialist academic publisher ELSEVIER.
Air pollution can have a severe impact on public health. Today, a large fraction of the world’s urban population is exposed to elevated concentrations of fine dust regularly. A novel approach to lower the local particle concentrations at urban hotspots is ambient air filtration.
The authors placed a Palas® Fine dust measurement device Fidas® next to the B14 federal motorway “Am Neckartor” in Stuttgart for monitoring outdoor PM concentrations. The particle mass concentration was monitored by periodically opening and closing the filter and using an optical particle counter. Determine the effect of Palas® Fine dust measurement device Fidas® on PM10 and PM2.5 concentrations. After a 466-hour long-term study, PM10 at the measurement site was reduced by an average of 10.4%. And the effect can be clearly measured in the aisle area of the entire installation site.
Fidas® 200 S is an aerosol spectrometer developed specifically for regulatory air pollution control. It analyzes continuously the fine dust particles present in the ambient air in the size range 180 nm – 18 µm and calculates simultaneously the immission values PM10 and PM2.5 to be monitored by law. At the same time PM1, PM4, PMtot, the particle number concentration Cn and the particle size distribution are calculated and recorded. It thus delivers comprehensive information about the fine dust particles, as only provided by a counting, single-particle measuring principle.
In this article, the authors describe in detail the process of using Fidas® for air quality monitoring and the method of comparing the monitoring data in the experiment.
