Study Finds Levoglucosan Degradation Skews Air Pollution Source Data

New research indicates that levoglucosan, a common tracer for biomass burning in air pollution, degrades significantly in the atmosphere before measurement. This degradation, estimated at up to 88%, can lead to inaccurate identification of air pollution sources, especially in tropical areas with high sunlight. Correcting for this atmospheric loss is essential for developing effective strategies to mitigate pollution.
