Open topic
Organic compounds make up 20 – 90% of fine atmospheric aerosol, and a large part of them is soluble in water because it undergoes many oxidation reactions in the atmosphere. The aim of this work will be to determine the proportion of primary and secondary aerosols of anthropogenic and biogenic origin by measurement of the concentration and size distribution of molecules determined using a combination of methods of ion chromatography with mass spectrometry and high-performance anion-exchange chromatography with pulsed amperometric detection or other methods.
Samples will be collected at various stations in the Czech Republic using large-volume samplers and large-volume cascade impactors. Size-differentiated samples will then enable us to determine more closely the age and origin of these compounds.
Required education and skills
