Dr Tom Smith is a wildfires scientist. His career has focused on tracking down wildland fires in savannahs and tropical peatlands around the globe, but his latest investigation was closer to home.
It took place on a weekend in early December. “I noticed the familiar smell of wood smoke inside my flat,” Smith said. “I’m well aware of its harmful health effects from my research, so I went outside with my portable pollution sensor in search of the source.”
