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 ... -
Characterisation of air masses passing over the Vredefort Dome world heritage site
(North-West University (South Africa), 2015)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 ... -
A critical evaluation of local government air quality management: the Gauteng experience
(North-West University (South Africa), 2020)Environmental governance is complex in South Africa and is subject to a fragmented and ever-changing legislative framework. The National Environmental Management Air Quality Act, No. 39 of 2004 (NEMAQA) was promulgated in ... -
Evaluating the effectiveness of air quality management plans as a governance instrument in South Africa
(North-West University (South Africa), 2023-10)Since the 19th century, industrialised societies introduced technologies to enhance economic production and productivity, most notably related to energy generation. These caused ever-increasing levels of air pollution. The ... -
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 ...
