“…Nitrate and PAN type compounds are potential wildfire/biomass burning degradation products, although field observations and laboratory studies are extremely limited. Furoyl peroxynitrate (C 4 H 3 O−C(O)−OONO 2 ), formed following the atmospheric degradation of 2-furfural, 165 is the only furanoid nitrate to be reported in wildfire plumes to date. UV spectra or photolysis product studies of furanoid nitrates are currently not available, but it is expected that initial photolysis occurs at the O−NO 2 bond.…”

“…The authors observed IR bands associated with the presence of −ONO 2 and −OONO 2 groups, suggesting the formation of organic nitrates. It is likely that these products include furoyl peroxynitrate (fur-PAN), which has been observed in aged biomass burning plumes and whose properties have been studied by Roberts et al 165 Other furanaldehydes, including 3-furfural and 5-methyl-2-furfural, are also likely to form peroxynitrates, though no studies have experimentally evaluated the product yields of these potential NO x reservoirs.…”

Furanoids are a class of reactive volatile organic compounds that are major products from the pyrolysis and combustion of biomass polymers, including cellulose, hemicellulose, and lignin. Biomass burning is an atmospheric source of furanoids that is increasing in frequency and intensity throughout regions of the world. Once emitted to the atmosphere, furanoids may react with the major atmospheric oxidants to form secondary pollutants that are hazardous to human health, including ozone (O 3 ) and secondary organic aerosol (SOA). This review is a comprehensive assessment of the literature between 1977 and the present describing the emissions and atmospheric fate of furanoids emitted from wild, prescribed, and domestic fires. The review is organized by presenting the physical properties of key furanoids first, followed by a summary of the biopolymer pyrolysis and combustion reactions that lead to furanoid formation. Next, furanoid emissions factors are compiled across the typical fuels consumed by biomass burning to highlight the key species emitted in smoke. We next review the available kinetic and atmospheric degradation mechanism data that characterize the reaction rates, gas-phase products, and SOA formed as a result of furanoid reactions with OH, NO 3 , O 3 , and Cl radicals. We then describe studies that have focused on evaluating furanoid atmospheric chemistry and their impacts on air quality using a combination of field observations and model simulations. We conclude with a perspective that identifies future research directions that would address key data gaps and improve the understanding of furanoid atmospheric processes.

Abstract. Many atmospheric chemicals occur in the gas phase as well as in liquid cloud droplets and aerosol particles. Therefore, it is necessary to understand their distribution between the phases. According to Henry’s law, the equilibrium ratio between the abundances in the gas phase and in the aqueous phase is constant for a dilute solution. Henry’s law constants of trace gases of potential importance in environmental chemistry have been collected and converted into a uniform format. The compilation contains 46 434 values of Henry’s law constants for 10 173 species, collected from 995 references. It is also available on the internet at https://www.henrys-law.org (last access: October 2023). This article is a living review that supersedes the now obsolete publication by Sander (2015).

Contribution of cooking emissions to the urban volatile organic compounds in Las Vegas, NV

Abstract. Cooking is a source of volatile organic compounds (VOCs), which degrade air quality. Cooking VOCs have been investigated in laboratory and indoor studies, but the contribution of cooking to the spatial and temporal variability in urban VOCs is uncertain. In this study, a proton-transfer-reaction time-of-flight mass spectrometer (PTR-ToF-MS) is used to identify and quantify cooking emission in Las Vegas, NV, with supplemental data from Los Angeles, CA, and Boulder, CO. Mobile laboratory data show that long-chain aldehydes, such as octanal and nonanal, are significantly enhanced in restaurant plumes and regionally enhanced in areas of Las Vegas with high restaurant densities. Correlation analyses show that long-chain fatty acids are also associated with cooking emissions and that the relative VOC enhancements observed in regions with dense restaurant activity are very similar to the distribution of VOCs observed in laboratory cooking studies. Positive matrix factorization (PMF) is used to quantify cooking emissions from ground site measurements and to compare the magnitude of cooking with other important urban sources, such as volatile chemical products and fossil fuel emissions. PMF shows that cooking may account for as much as 20 % of the total anthropogenic VOC emissions observed by PTR-ToF-MS. In contrast, emissions estimated from county-level inventories report that cooking accounts for less than 1 % of urban VOCs. Current emissions inventories do not fully account for the emission rates of long-chain aldehydes reported here; thus, further work is likely needed to improve model representations of important aldehyde sources, such as commercial and residential cooking.
