New publication in Communications Earth & Environment: Environmentally persistent free radicals are ubiquitous in wildfire charcoals and remain stable for years


Every year, an estimated four percent of the world's vegetated land surface burns, leaving more than 250 megatons of carbonized plants behind. This study found that wildfire charcoal is an important source of environmentally persistent free radicals (EPFR), precursors to toxic reactive oxygen species. Researchers from the University of Vienna and Swansea University published their findings in Nature Communications Earth & Environment. Gabriel Sigmund the lead author of the study also published an accompanying “behind the paper” blogpost for nature ecology & evolution.
