Summary of research paper published in Atmospheric Chemistry and Physics titled: Spatial, temporal and source contribution assessments of black carbon over the northern interior of South Africa
(NACA, 2017)
According to the latest assessment report of the
Intergovernmental Panel on Climate (IPCC), aerosol black
carbon (BC) is considered the second most ...
Cr(VI) generation during sample preparation of solid samples - a chromite ore case study
(WRC, 2010)
South Africa holds more than 70% of the world's viable chromite ore reserves and produces ~46.2% of the world's high carbon ferrochrome. It was recently reported that beneficiated South African chromite ores contained ...
Long-term observations of aerosol size distributions in semi-clean and polluted savannah in South Africa
(EGU, 2013)
This study presents a total of four years of sub-micron aerosol particle size distribution measurements in the southern African savannah, an environment with few previous observations covering a full seasonal cycle and the ...
The chemical composition and fluxes of atmospheric wet deposition at four sites in South Africa
(Elsevier, 2016)
South Africa is the economic hub of southern Africa and is regarded as an important source region of atmospheric pollutants. A nitrogen dioxide (NO2) hotspot is clearly visible from space over the South African Mpumalanga ...
Multiple daytime nucleation events in semi-clean savannah and industrial environments in South Africa: analysis based on observations
(EGU, 2013)
Recent studies have shown very high frequencies of atmospheric new particle formation in different environments in South Africa. Our aim here was to investigate the causes for two or three consecutive daytime nucleation ...
Determining the baking isotherm temperature of Söderberg electrodes and associated structural changes
(Elsevier, 2013)
One of the most commonly employed electrode systems in industrial metal smelting applications is continuous self-baking electrodes, i.e. the Söderberg electrode system. In this system, the temperature at which transition ...
Correction for a measurement artifact of the Multi-Angle Absorption Photometer (MAAP) at high black carbon mass concentration levels
(EGU, 2013)
The Multi-Angle Absorption Photometer (MAAP) is a widely-used instrument for aerosol black carbon (BC) measurements. In this paper, we show correction methods for an artifact found to affect the instrument accuracy in ...
General overview: European integrated project on Aerosol Cloud Climate and Air Quality Interactions (EUCAARI): integrating aerosol research from nano to global scales
(EGU, 2011)
In this paper we describe and summarize the main achievements of the European Aerosol Cloud Climate and Air Quality Interactions project (EUCAARI). EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a ...
Characterisation and liberation of chromium from fine ferrochrome waste materials
(Elsevier, 2014)
Three types of generic chromium (Cr)-containing wastes are generated during ferrochrome (FeCr) production,
i.e. slag, bag filter dust (BFD) and venturi sludge. Slag is by volume the largest waste; however,
fine FeCr waste ...
A survey of Cr(VI) contamination of surface water in the proximity of ferrochromium smelters in South Africa
(WRC, 2014)
South Africa holds approximately three-quarters of the world’s viable chromite ore reserves and is one of the largest ferrochrome producers. It is impossible to completely exclude oxygen from all high-temperature ferrochrome ...
