Aerosol source apportionment in southern Africa
(North-West University (South Africa), 2021)South Africa, and especially the Highveld region, contributes significantly to the atmospheric aerosol loading over southern Africa. South Africa has recognised the importance of localised air quality and its impact on ... -
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 ... -
Determination of the occurrence of toxic trace metals at two sites in the North West Province using size of atmospheric aerosols
(2012)The concentration levels of atmospheric aerosols of different sizes of particulate matter namely PM 10, PM 2.5, PM 1 and PM <1 were determined in the North West province mining towns of Rustenburg which is a platinum ... -
Impacts of coal-fired power plants on aerosol particles in the Highveld
(North-West University (South Africa), 2023)Industrialisation and urbanisation of the interior plateau of South Africa (i.e. the Highveld) have resulted in air quality that infringes on South Africans' right to an environment that is not damaging to human health or ... -
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 ... -
Observation and quantification of aerosol outflow from southern Africa using spaceborne lidar
(ASSAf, 2020)Biomass burning in Africa provides a prolific source of aerosols that are transported from the source region to distant areas, as far away as South America and Australia. Models have long predicted the primary outflow and ... -
Plume characterization of a typical South African braai
(SACI, 2015)To braai is part of the South African heritage that transcends ethnic barriers and socio-economic groups. In this paper, a comprehensive analysis of atmospheric gaseous and aerosol species within a plume originating from ... -
Sensitivity of simulated clouds to aerosols in the Benguela Region
(North-West University (South Africa), 2023)Aerosol-cloud interactions have been studied since the 1970s. The interactions of the processes, such as aerosols’ direct, semi-direct, and indirect effects on clouds in the atmosphere, are complex. There are large ... -
Spatial, temporal and source contribution assessments of aerosol black carbon over the northern interior of South Africa
(North-West University (South Africa). Potchefstroom Campus, 2019)After carbon dioxide (CO2), aerosol black carbon (BC) is considered to be the second most important contributor to global warming. Africa is one of the least studied continents, although it is regarded as the largest source ... -
Temporal assessment of atmospheric trace metals in the industrialised western Bushveld Complex
(North-West University, 2011)The presence of trace transition metal species in the atmosphere can be attributed to the emission of particulate matter into the atmosphere by anthropogenic activities, as well as from natural sources. Trace metals ...
