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 ... -
Emissions management and health exposure: should all power stations be treated equal?
Pretorius, Ilze; Piketh, Stuart; Burger, Roelof (Springer, 2017)At the centre of all air quality regulation stands the right of humans to an environment that is not harmful to health and well-being. In many developing countries, including South Africa, coal-fired power station emissions ... -
OMI satellite and ground-based Pandora observations and their application to surface NO2 estimations at terrestrial and marine sites
Kollonige, Debra E.; Thompson, Anne M.; Josipovic, Miroslav; Beukes, Johan P.; Burger, Roelof; Van Zyl, Pieter G.; Laakso, Lauri (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 ... -
A perspective on South African coal fired power station emissions
Pretorius, Ilze; Piketh, Stuart; Burger, Roelof; Neomagus, Hein (Energy Research Centre, University of Cape Town, 2015)This paper investigates trends of historical and projected future South African coal-fired power station criteria (total primary Particulate Matter (PM), Sulphur Dioxide (SO2) and Nitrogen Oxides (NOx)) and Carbon ... -
Three years of measurements of light-absorbing aerosols over coastal Namibia: seasonality, origin, and transport
Formenti, Paola; Piketh, Stuart John; Klopper, Danitza; Burger, Roelof; Broccardo, Stephen; Walton, Nicola (EGU, 2018)Continuous measurements between July 2012 and December 2015 at the Henties Bay Aerosol Observatory (HBAO; 22∘ S, 14∘05′ E), Namibia, show that, during the austral wintertime, transport of light-absorbing black carbon ...
