Despite the relevance of furanic compounds as atmospheric pollutants, role water molecule in their oxidation mechanisms still needs to be comprehended. Here, we present new insights into furan's water-mediated hydrogen abstraction mechanism by OH radical and its implications. Compared naked mechanism, addition monomer increases chemical complexity, yielding three six pathways for on α β carbons, respectively. Employing pre-equilibrium model, calculate termolecular rate constants then estimate effective reaction a function relative humidity. Our results suggest that effect is negligible. In addition, also determined at stratosphere 5 orders magnitude slower compared troposphere.

Wildfires at the wildland–urban interface (WUI) have been increasing in frequency over recent decades due to increased human development and shifting climatic patterns. The work presented here focuses on impacts of a WUI fire indoor air using field measurements volatile organic compounds (VOCs) by Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS). We found slow decrease VOC mixing ratios course roughly 5 weeks starting 10 days after fire, those levels decreased ∼20% initial value average. composition could be described combination biomass burning emissions composition. Comparisons were made between polycyclic aromatic hydrocarbon (PAH) distributions gas phase ash, with differences observed their distribution each other when compared fresh fuel inventory measurements. Mitigation tests conducted running cleaners activated carbon opening windows promote indoor–outdoor exchange, both methods showing greater than 50% for average indoors while active. compare our results simulated smoke impact experiments that show decline VOCs must understood context reservoirs, beyond just surfaces, leading release air.

Residential biomass combustion emits a large amount of organic gases into ambient air, resulting in the formation secondary aerosol (SOA) and various environmental health impacts. In this study, we investigated emission characteristics non-methane compounds (NMOCs) from residential fuels during vigorous (flaming) stable (smoldering) conditions. We quantified NMOC factors based on CO concentration for different phases found that emissions were higher smoldering phase approximately two to four times greater than those flaming. NMOCs categorized volatile (VOCs) intermediate-volatility (IVOCs) through modeling compound volatility distribution. The photochemical aging revealed furans, phenolics, certain IVOCs as significant non-traditional SOA precursors, with over half being consumed short period. A parametric function was established, indicating accounting precursors IVOC yields improves representation net enhancement measured (OA). This study emphasizes importance differentiating recognizing accurate assessment prediction.
