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 ...
Assessing atmospheric trace gas concentrations in rural areas of the North West Province
(North-West University (South Africa), 2020)
Anthropogenic activities are increasing the ambient atmospheric concentrations of inorganic gaseous pollutants, which include nitrogen dioxide (NO₂), sulphur dioxide (SO₂), and ozone (O₃). These species were also included ...
Factors governing rain chemistry and wet deposition at a regional background site in South Africa
(North-West University (South Africa), 2020)
Wet deposition is an atmospheric sink that is essential to sustain the Earth-atmosphere biogeochemical balance. Deposited species can either be introduced as nutrients or toxins into a surface environment, which can be ...
Aerosol optical properties at a savannah grassland site in South Africa
(North-West University (South Africa), 2020)
Atmospheric aerosols affect the earth’s radiative budget in two ways: firstly, particles directly absorb and scatter short- and long-wave radiation and, secondly, particles indirectly influence the lifetime and physical ...
