Air quality assessment of the industrialized western Bushveld Igneous Complex
(North-West University, 2011)South Africa has the largest economy in Africa, with significant mining and metallurgical activities. A large fraction of the mineral assets is concentrated in the Bushveld Igneous Complex (BIC), with the western limb ... -
Atmospheric dry and wet deposition of sulphur and nitrogen species and assessment of critical loads of acidic deposition exceedance in South Africa
(ASSAf, 2011)We tested the hypothesis that acidic atmospheric pollution deposition, originating from the South African central industrial area, poses an environmental threat across a larger region within the dispersal footprint. A ... -
Atmospheric SO₂ and NO₂ flux measurements at a savannah-grassland-agriculture landscape in South Africa
(North-West University (South Africa), 2019)Deposition measurements of SO2 and NO2 in South Africa are mainly limited to passive sampling where a constant deposition velocity is assumed for a specific land use category. Gaseous deposition velocities in South Africa ... -
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 ... -
Spatial and temporal assessment of gaseous pollutants in the Highveld of South Africa
(ASSAf, 2011)Diverse natural and anthropogenic activities in the Highveld of South Africa contribute to elevated levels of inorganic and organic gaseous pollutant species. The primary aims of this investigation were to determine spatial ...
