Professor Gwen O’Sullivan and Nadin Boegelsack, environmental forensics researchers at Mount Royal University in Alberta, Canada, investigate the causes of wildfires by searching for ignitable liquid residues (ILRs) – remnants of accelerants – in wildfire debris samples. Determining the presence of an ILR and the type and source of accelerant used in arsonous fires can provide key evidence for conviction in arson cases.
