Assessment of the indoor air quality at the corporate offices of a South African mining company
(2013)The aim of the study was to evaluate the indoor air quality (IAQ) of a semi-airtight (the building only utilises mechanical means to ventilate the occupied spaces however an airtight seal is not established as a result of ... -
Blootstelling aan stof, geraas en waterstoffluoriedgas in 'n kunsmisfabriek en die gesondheidsgevare verbonde daaraan
(North-West University (South-Africa), 1999)In this study three environmental stressors were monitored, namely noise, superphosphate dust and hydrogen fluoride gas. The purpose of the study was to quantify the exposure to superphosphate dust and hydrogen fluoride ... -
Die blootstelling van werkers aan vlugtige organiese oplosmiddels by pad- en spoorlaairakke van 'n petrochemiese nywerheid
(Potchefstroom University for Christian Higher Education, 2002)BACKGROUND: The liver serves as a first pass filter and is an important metabolising organ for VOC's. Thus the concentration that the liver is exposed to is higher than that of other organs. The substances have different ... -
Characterisation of airborne dust in a South African opencast iron ore mine : a pilot study
(2013)The iron ore mining industry makes use of various processes that result in the release of airborne dust into the surrounding atmosphere where workers are exposed, to produce a final product. The deposition in the lung and ... -
Characterisation of airborne dust in South African underground and opencast coal mines : a pilot study
(2015)Dust is a well-known occupational hygiene challenge and has been throughout the years, especially in the coal mining industry. The hazards arising from coal dust will differ between geographical areas due to the unique ... -
Comparison of airborne particulate exposure in two platinum refining process areas
(North-West University, 2010)The aims and objectives: The aims and objectives of this study were to characterize and compare the airborne particulate matter in the tankhouse and crusher areas of a base metal refinery sampled with two separate methods, ... -
Die invloed van lugdrukbeitel geïnduseerde vibrasie en geraas op die kardiovaskulêre sisteem van die mens
(North-West University (South-Africa), 1996)The effect of repeated handling of a hand-held pneumatic tool on the cardiovascular system of the operator was studied. The stressors vibration, noise, combination of vibration and noise and muffled noise were evaluated. ... -
Diesel particulate matter and polynuclear aromatic hydrocarbon exposure of diesel vehicle operators in small to medium sized underground coal mines
(North-West University, 2010)Limited data is currently available for diesel particulate matter (DPM) and polynuclear aromatic hydrocarbon (PAH) exposure in underground coal mines in South Africa. The lack of regulatory exposure limits for DPM and PAH ... -
DNA damage and repair detected by the comet assay in lymphocytes of African petrol attendants : a pilot study
(North-West University, 2007)Petrol attendants are exposed to petrol volatile organic compounds (VOCs) which may have genotoxic and carcinogenic effects. The single cell gel electrophoresis assay (comet assay) is a method highly sensitive to DNA damage ... -
DNA damage and repair in nail technicians caused by occupational exposure to volatile organic compounds
(North-West University, 2010)Objectives: The aim of this study was to determine if exposure to volatile organic compounds can lead to DNA damage and impaired DNA repair capacity. Nail cosmetics is a fast growing industry around the world where employees ... -
Die effek van ototoksiese koolwaterstowwe op die gehoordrempels van werkers by 'n petrochemiese fabriek
(North-West University, 2004)The aim of this study was to determine in an empirical manner whether the phenomenon of hearing loss due to the exposure to volatile organic solvents was present in the gasification plants of a petrochemical factory. The ... -
Evaluation of DNA damage and DNA repair by the comet assay in workers exposed to organic solvents
(North-West University, 2004)Rapid development of the chemical industry over the past two decades makes the study of the effects of chemical substances (such as benzene) on the human body essential, Benzene toxicity involves both bone marrow depression ... -
Evaluation of exposure to airborne soluble platinum in a precious metal refinery during non–routine operations
(North-West University, 2011)Background: Platinum refinery workers are exposed to various elements during the refining process, with soluble platinum salts posing a potential health risk. Platinum salts are extremely potent sensitisers that can result ... -
Evaluation of surface sampling methods for platinum salts
(North-West University, 2010)Motivation: The health effects of platinum on the human body are a great concern. It affects the respiratory system as well as the skin. The demands for platinum have seemingly increased over the last few years due to its ... -
Evaluation of thermal desorption as an alternative technique for the measurement of coal tar pitch volatiles
(North-West University, 2011)Motivation: The accurate and reliable measurement of the concentration of coal tar pitch volatiles (CTPVs) in ambient air has proved to be a challenge for occupational hygienists. The challenge must however be confronted ... -
Exposure of welders to manganese in welding fumes
(North-West University, 2012)Aims and objectives: The general aim of this study was to determine the personal respiratory exposure and biological monitoring of manganese (Mn) present in welding fumes as well as its neurological influence on welders. ... -
Exposure to hand–arm vibration and its effects on workers at a mine rock drill repair and maintenance workshop
(North-West University, 2012)In many occupations, exposure to hand-transmitted vibration (HTV) over a prolonged period causes various disorders involving the vascular, neural and musculoskeletal systems, collectively known as the hand-arm vibration ... -
Die hematologiese profiel van persone werksaam by 'n koolteeraanleg van 'n petrochemiese fabriek
(Potchefstroom University for Christian Higher Education, 2000)BACKGROUND: Oxygen is essential for life. If any factor inhibits the body's usage of oxygen, the body will react with a variety of feedback systems to retain life. When a person stays in an area with a slightly lower oxygen ... -
The influence of occupational exposure to sulphuric acid mist on skin barrier function in a base metal refinery
(2014)Motivation: The skin is the primary barrier between the internal and external environment. Damage to this barrier will lead to adverse health effects such as water loss through the skin as well as the absorption of exogenous ... -
An investigation into visual problems of crane operators at a petrochemical factory and the possible link with exposure to hydrocarbons
(North-West University, 2004)The aim of this investigation was to determine the exposure to total hydrocarbons including toluene and to determine if there are any relation between exposure to toluene and visual problems experienced by crane operators. ...
