Assessment of polar organic aerosols at a regional background site in southern Africa
Booyens, Wanda; Beukes, Johan P.; Van Zyl, Pieter G.; Josipovic, Miroslav; Laakso, Lauri (Springer, 2019)A recent paper reported GCxGC-TOFMS analysis used for the first time in southern Africa to tentatively characterise and semi-quantify ~1000 organic compounds in aerosols at Welgegund – a regional background atmospheric ... -
Characterising particulate organic nitrogen at a savannah-grassland region in South Africa
Booyens, Wanda; Van Zyl, Pieter G.; Beukes, Johan P.; Vakkari, Ville; Josipovic, Miroslav; Laakso, Lauri (MDPI, 2019)Although atmospheric organic N compounds are considered to be important, especially in new particle formation and their contribution to brown carbon, these species are not that well understood. This can be partially ... -
Plume characterization of a typical South African braai
Venter, A.D.; Jaars, K.; Booyens, W.; Beukes, J.P.; Van Zyl, P.G.; Josipovic, M.; Hendriks, J.; Laakso, L. (SACI, 2015)To braai is part of the South African heritage that transcends ethnic barriers and socio-economic groups. In this paper, a comprehensive analysis of atmospheric gaseous and aerosol species within a plume originating from ... -
Size-resolved characterisation of organic compounds in atmospheric aerosols collected at Welgegund, South Africa
Booyens, Wanda; Van Zyl, Pieter G.; Beukes, Johan P.; Josipovic, Miroslav; Venter, Andrew D.; Jaars, Kerneels; Pienaar, Jacobus J.; Laakso, Lauri (Springer, 2015)The organic fraction of atmospheric aerosols is 20 to 90 % of which only a small percentage has been chemically characterised. Two-dimensional gas chromatography with a time-of-flight mass spectrometer (GCxGC-TOFMS) is a ... -
