David Megson

David Megson is currently a reader in chemistry and environmental forensics at Manchester Metropolitan University (UK). He also works on pollution litigation cases as a senior environmental consultant at Chemistry Matters (Canada). Megson investigates sources of legacy and emerging persistent organic pollutants and monitors them in the environment using advanced analytical techniques, including multidimensional chromatography and high-resolution mass spectrometry. Much of Megson’s research has an environmental forensics aspect, which involves identifying sources of contamination, transport pathways, and the magnitude of pollutant exposure. As a recognized international expert in this area, he regularly contributes to expert witness reports for large (>$100 million) litigation cases involving environmental pollution in North America.
