An air quality assessment in the industrialised western Bushveld Igneous Complex, South Africa
(ASSAf, 2012)South Africa has the largest industrialised economy in Africa, with significant mining and metallurgical activities. A large fraction of the South African mineral assets is concentrated in the Bushveld Igneous Complex ... -
Assessment of atmospheric trace metals in the western Bushveld Igneous Complex, South Africa
(ASSAf, 2014)Trace metal species emitted into the atmosphere from natural and anthropogenic sources can cause various health-related and environmental problems. Limited data exist for atmospheric trace metal concentrations in South ... -
A comparison of surface NO2 mixing ratios and total column observations at a South African site
(SASAS, 2014)The total column density nitrogen dioxide (NO2) retrievals collated by a ground-based sun-tracking spectrometer (Pandora/GSFC) and the satellite-borne (Aura) Ozone Monitoring Instrument (OMI) were compared to the volume ... -
Modelling new particle formation events in the South African savannah
(ASSAf, 2014)Africa is one of the less studied continents with respect to atmospheric aerosols. Savannahs are complex dynamic systems sensitive to climate and land-use changes, but the interaction of these systems with the atmosphere ... -
Size-resolved characterisation of organic compounds in atmospheric aerosols collected at Welgegund, South Africa
(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 ...
