Biography

Bongani Yalala is a Lecturer in the department of Applied Chemistry in the National University of Science and Technology, Zimbabwe.

Research Interest

Environmental research, which focuses on the speciation of inorganic and organic pollutants, their transport and fate, biogeochemical cycles of heavy metals, determination of bioavailability and bioaccessibility of heavy metals, health and environmental risk assessment studies due to exposure to pollutants, and application of new materials (adsorbents) for pollutant extraction of remediation studies. To achieve these research objectives, routine analytical techniques are employed to generate data, chemometric and statistical evaluation are used to validate the data, and geochemical modelling (predicting elemental speciation, solution equilibria, and secondary mineral formation) to understand and explain the transportation, mobility, fate of pollutants, and predict the outcome and fate of pollutants when environmental conditions change.
