Rohwer, Egmont Richard Geldenhuys, Genna-Leigh UCTD Denuder Underground Platinum mines Diesel Particulate Matter Diesel exhaust emissions Dissertation (MSc)--University of Pretoria, 2014. Concentrations of diesel particulate matter (DPM) and polycyclic aromatic hydrocarbons (PAHs) in platinum mine environments are likely to be higher than in ambient air due to the use of diesel machinery in confined environments. PAHs may be present in gaseous or particulate phases each of which have different human health impacts due to their ultimate fate in the body. The sampling of both phases was made possible by means of small, portable denuder sampling devices consisting of two polydimethylsiloxane multi-channel traps connected in series and separated by a quartz fibre filter. Thermal desorption coupled with two dimensional gas chromatography with mass spectrometric detection (TD-GCxGC-ToFMS) was employed to analyse samples from three different platinum mines. The underground environments revealed that PAHs were predominantly found in the gaseous phase with naphthalene and mono-methylated derivatives being detected in the highest concentrations ranging from 0.15 – 8.73 μg.m-3. Similarly higher gas phase PAH loading was found in the Daspoort Tunnel. The particle bound PAHs underground were found in the highest concentrations at the Load Haul Dump (LHD) vehicle exhaust with dominance of fluoranthene and pyrene and concentrations ranged from 0.52-109.60 ng.m-3. This work highlighted the need to characterise both gaseous and particulate phases of PAHs in order to assess occupational exposure and demonstrated the successful application of these portable denuders in the mining environment. tm2015 Chemistry MSc Unrestricted 2015-07-02T11:08:28Z 2015-07-02T11:08:28Z 2015/04/16 2014 Dissertation Geldenhuys, G 2014, Characterization of diesel emissions with respect to semi-volatile organic compounds in South African platinum mines and other confined environments, MSc Dissertation, University of Pretoria, Pretoria, viewed yymmdd <http://hdl.handle.net/2263/46248> A2015 http://hdl.handle.net/2263/46248 en © 2015 University of Pretoria.
