Article Synopsis
- Biomass burning (BB) emits significant carbonaceous aerosols that irritate airways, with key markers like levoglucosan (LG) and the harmful nitro-aromatic compound 4-nitrocatechol (4NC) formed through atmospheric aging.
- The study compares the toxic effects of 4NC and LG on human lung cells, revealing that 4NC is more potent and induces apoptosis more readily than LG, especially in specific lung cell lines.
- Findings indicate that while both compounds lead to reactive oxygen species (ROS) imbalance and mitochondrial dysfunction, 4NC exposure poses higher risks for respiratory health due to its stronger toxicity at lower concentrations compared to LG.
