Research areas
Development and application of modern analytical procedures for characterising and monitoring pollutants in the environment
These projects use modern analytical techniques to resolve environmental problems.
SMPS, ICPMS, GCMS, Particle Size Analyzer, TOC Analyzer, and chemometrics techniques have been used in recent studies on:
- emissions of ultrafine and nanoparticles
- elements and organic compounds from motor vehicles
- analysis of priority pollutants in soil, house dust, stormwater and ambient/indoor air.
Application of multivariate data analysis techniques to chemical data
These projects apply multivariate data projection techniques and multi-criteria decision-making procedures to data obtained from the following types of studies:
- environmental
- clinical
- drug screening
- chromatographic
- spectroscopic.
These techniques:
- recognise patterns in the data
- predict outcomes
- facilitate decision-making.
We are exploring the use of more complex factor analysis techniques.
Receptor modelling and source apportionment of pollutants in air, water and soil/dust samples
The projects use receptor models and meteorological data to:
- unveil hidden structures in chemical data
- identify plausible pollution sources
- estimate their compositions
- identify their possible locations
- quantify their contributions to pollution at different receptor sites.
This should assist the development, planning and prioritisation of pollution control strategies.
Synthesis, characterisation and application of organometallic and inorganic compounds
These projects involve the synthesis, characterisation, reactivity and application of organometallic/inorganic compounds that may be used for specific purposes, e.g. removal of environmental pollutants, use as anti-fungi and anti-tumour agents etc.
