One specific objective of the AEROMET project is to apply mobile X-ray spectroscopy techniques combined with particle sampling techniques to quantify particle compositions in the field for real time analysis. Results are then corroborated by a backup lab-based reanalysis of samples.
During summer 2018 two on-site campaigns were conducted in Hungary and Italy. Aerosols were captured with different sampling technologies, e.g. a Dekati 13 stage impactor, which fractionates particles in the range from 0.03 to 10 µm. Sampling was performed on acrylic discs, which were directly measured with one of Bruker's TXRF spectrometers without any further treatment. Even after short sampling times, toxic elements like Ni, Pb, As could be quantified and related to specific particle fractions.
