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 ... -
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 ... -
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 ... -
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 ... -
The composition of ambient and fresh biomass burning aerosols at a savannah site, South Africa
(ASSAf, 2016)Atmospheric aerosols play a key role in climate change, and have adverse effects on human health. Given South Africa’s status as a rapidly-developing country with increasing urbanisation and industrial growth, information ... -
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 ... -
Environmental education's influence on awareness and perception of air quality in Grade 5 learners and their parents/guardians
(North-West University (South Africa)., 2023)Education is an essential right. Education aims to form open-minded citizen scientists that will focus on real-world issues. Environmental education offers learners the opportunity to gain familiarity with sustainability ... -
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 ... -
OMI satellite and ground-based Pandora observations and their application to surface NO2 estimations at terrestrial and marine sites
(Wiley, 2018)The Pandora spectrometer that uses direct-Sun measurements to derive total column amounts of gases provides an approach for (1) validation of satellite instruments and (2) monitoring of total column (TC) ozone (O3) and ...
