PhD (reading) MPhil Nuclear & Environmental Protection, University of Ghana, 2011 BSc Chemistry, University of Ghana, 2007
Gustav is a PhD candidate, currently investigating the transformation and degradation processes of polycyclic aromatic hydrocarbons (PAHs) in road dust, a major repository of PAHs in an urban environment leading to the generation of some toxicologically enhanced transformed PAH products.
Research Interests
- Development and optimization of rapid and cost-effective analytical methods for assessing various hazardous and emerging micro-organic pollutants
- Evaluation of the health and ecological risks posed by various hazardous pollutants through modelling
- Implementation of effective and sustainable disposal measures for radioactive waste materials is of keen interest in line with the International Atomic Energy Agency’s (IAEA) safety protocols
Current Project
Stormwater pollution is a critical environmental issue. Mitigating stormwater pollution is essential in safeguarding human health and the ecosystem. Remedial measures are designed typically based on the assumption that hazardous stormwater organic pollutants sorbed to solid particles persist in their originally emitted form. This research characterized the transformation and degradation processes of polycyclic aromatic hydrocarbons (PAHs) in road dust, a major repository of PAHs in an urban environment. Pressurized fluid extraction (PFE) and triple-quadrupole gas chromatography analytical methods were developed and optimized to holistically measure these pollutants. A novel risk assessment approach via the quantitative structure-activity relationship (QSAR) modeling of the toxicity equivalency factors (TEFs) has also been developed to evaluate the carcinogenic health risk associated with PAHs and their resultant transformed products. The new knowledge gained has been used to define the fate and pathways of PAHs in stormwater environment leading to the greater protection of the ecosystem and human health.
