As part of a NERC funded PhD, I am currently studying spatial and temporal variations in potentially toxic elemental (Sb, Pb, Cu and Zn) and polycyclic aromatic hydrocarbon (PAH) concentrations and associations in run-off from urban and rural areas of Scotland. Supervised by Margaret Graham, the research is part of the University of Edinburgh’s Global Change Research Institute in the School of GeoSciences.
The effect of climate change and the induced perturbations in weather patterns is changing how potentially toxic elements and PAH concentrations are stored in the environment; contaminants that were previously bound to soil have increased mobility due to extreme weather from flooding and droughts. The key aim of the project is to research this area and identify the principal geochemical processes influencing the fate of elements and PAHs.
After graduating with a BSc, I joined the Scottish Environment Protection Agency (SEPA) where I studied part-time to complete an MSc with distinction in Instrumental Analytical Chemistry for Environmental Monitoring. Although my initial time at SEPA was spent reporting and analysing environmental samples for organic contaminants using instrumentation such as Gas Chromatography and Liquid Chromatography. The majority of my time was spent developing SEPA’s lipophilic monitoring network, where persistent organic pollutants were monitored in the freshwater environment using brown trout (Salmo trutta) and freshwater eels (Anguilla Anguilla) as bio-indicators. I gained valuable experience in the implementation of a national monitoring scheme and through the application of new analytical technologies, I developed multi-component analysis on triple quadruple mass spectrometers for environmental samples.
