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 ...
Recommendation of a classification system and occupational exposure limits for chemical carcinogens
(2015)
Introduction: An increased number of occupational cancers reported annually can be attributed to workers being exposed to hazardous chemical substances (HCSs) in their workplace. Carcinogen classification systems such as ...
Dermal exposure and skin barrier function of workers exposed to copper sulphate at a chemical industry
(2013)
Copper exposure is known to be a rare cause of skin irritation and allergic reactions and according to our knowledge occupational dermal exposure to copper sulphate has not yet been characterised. As a result, the objectives ...
Dermal exposure to platinum group metals at a precious metal refinery : a pilot study
(2014)
Background: Workers in a platinum group metals (PGMs) refinery are potentially exposed to various precious metals (iridium, osmium, palladium, platinum, rhodium and ruthenium) and their metal-salt compounds which may cause ...
The influence of pH on the in vitro skin permeation of rhodium
(2014)
In occupational settings where rhodium is produced or used, such as the mining industry, refineries and catalytic industries, workers are at risk of being dermally exposed to this metal in either the metallic form or its ...
In vitro skin permeation of selected platinum group metals
(2014)
Background: Platinum group metal (PGM) mining and refining is a large constituent of the mining sector of South Africa and contributes significantly to the gross domestic product. The PGMs include the rare metals platinum ...
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 ...
Dermal and respiratory exposure to cobalt salts in a packaging area of a base metal refinery
(North-West University, 2010)
Cobalt is a commonly known sensitiser in industrial settings and has been classified by the IARC as a possible group (2B) human carcinogen. Workers at a South African base metal refinery are potentially exposed to cobalt ...
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 ...
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. ...
