Mrs. Goitsemang Keretetse

Goitsemang Keretetse is an environmental and occupational health researcher whose work centers on exposure to volatile organic compounds in vulnerable worker populations in South Africa. Research consistently examines formal and informal sectors, with particular attention to nail technicians, petrol attendants, and informal food traders. This body of work highlights occupational inequalities and the health implications of low-level, chronic chemical exposures.

Publications demonstrate expertise in personal exposure monitoring, passive sampling, real-time air quality assessment, and biomonitoring techniques such as the comet assay for DNA damage. Studies on nail technicians provide comparative analyses of ventilation, work practices, and solvent profiles, while introducing participatory self-assessment methods to strengthen exposure datasets in resource-constrained settings.

Keretetse’s contributions extend to risk characterization, including non-carcinogenic and carcinogenic risk estimation for compounds such as benzene and formaldehyde. Earlier work linking petrol VOC exposure to genotoxic effects established a foundation for later applied research. Collectively, these studies advance occupational hygiene knowledge and inform practical interventions for safer working environments.
