    • Bird species richness and densities in relation to sulphur dioxide gradients and environmental variables 

      Muyemeki, Luckson; Burger, Roelof; Piketh, Stuart J.; Evans, Steven W. (Taylor & Francis, 2017)
      The expansion of coal-fired power stations in South Africa has resulted in growing environmental concerns as they are the largest emitters of sulphur dioxide (SO2). Sulphur dioxide emissions from power plants pose a potential ...

    • Coal-derived low smoke fuel assessment through coal stove combustion testing 

      Kühn, Thys; Bunt, John R.; Neomagus, Hein W.J.P.; Piketh, Stuart J.; Everson, Raymond C.; Coetzee, Sansha (Elsevier, 2017)
      A study was undertaken to investigate the production of low smoke fuel from coal currently used in low-income households in South Africa. Pyrolysis of large coal lumps was studied as a possible production method, and an ...

    • Investigating atmospheric photochemistry in the Johannesburg-Pretoria megacity using a box model 

      Lourens, Alexander S.M.; Beukes, J. Paul; Van Zyl, Pieter G.; Butler, Tim M.; Fourie, Gerhard D.; Lawrence, Mark G. (ASSAf, 2016)
      Urban air pollution has become a major concern over the past decades. One of the largest conurbations in Sub-Saharan Africa is developed around the cities of Johannesburg and Pretoria (Jhb-Pta megacity). In this study, ...

    • Moving households to cleaner energy through air quality offsets 

      Langerman, Kristy E.; Piketh, Stuart J.; Pauw, Christiaan J.; Smith, Hendrik J. (IEEE, 2018)
      Highest levels of exposure to polluted air in South Africa occur in low-income settlements where households burn solid fuels. The Department of Environmental Affairs has recently developed a legally enforceable mechanism ...

    • Ozone concentrations and their potential impacts on Vegetation in Southern Africa 

      Laakso, Lauri; Beukes, Johan Paul; Van Zyl, Pieter Gideon; Pienaar, Jacobus J.; Josipovic, Miroslav; Venter, Andrew; Jaars, Kerneels (Elsevier, 2013)
      The tropospheric ozone concentrations over southern Africa are relatively high due to large precursor emissions from biomass burning, vegetation and anthropogenic sources and the intensity of solar radiation. In this study, ...
