The toxic legacy of bushfires
Posted on: Fri 16 Oct 2020
We know that forests absorb carbon dioxide, but, like a sponge, they also soak up years of pollutants from human activity. However when bushfires strike, these pollutants are re-released into the air with the smoke and ash.
New research has examined air samples from four major bushfires near Sydney between 1984 and 2004 to determine the extent of pollutant release. To discuss the findings, Barometer’s Des Lawrence spoke to one of the researchers, Dr Cynthia Isley, Research Fellow in Environmental Science at Macquarie University.
