In 2007, it was announced that the Vredefort Dome will be proclaimed South Africa’s seventh UNESCO (United Nations Educational, Scientific and Cultural Organisation) world heritage site. It is the largest and second oldest ...
Applicability of analytical techniques to quantify trace metals in particulate matter for source apportionment in South Africa
(North-West University (South Africa), 2020)
The impacts of atmospheric trace metal species in particulate matter (PM) on human health and the environment is well documented. Rapid advances in the development of analytical techniques used for characterisation and ...
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 ...
Spatial and temporal deposition of selected biogeochemical important trace species in South Africa
(North-West University, Potchefstroom Campus, 2018)
The concern of potential adverse environmental effects due to increased anthropogenic emissions to
the atmosphere necessitates the need for long-term atmospheric deposition programmes. Wet and dry
depositions of emitted ...
