Use of drones to asses tropospheric quality
Problem: Pollution of the troposphere has a major impact on the health of the population. Despite the effort to reduce emissions at source, there may be situations where immision limit values are exceeded. These situations can be studied with drones that are significantly more flexible than automatic air pollution monitoring stations.
Solution: The developed semi-automatic atmospheric sampler is capable of selectively detecting concentrations of inorganic gases (SOx, H2S, NOx, O3, …) from the level of 5 μg/m3 as well as the size and concentration of dust particles. In this way, a three-dimensional model of the spread of pollution can be obtained. A qualitative analysis can be performed by capture of pollutants on suitable sorbents, followed by analysis using GC-HRMS.
