“…In addition, as described above, the field experiments are not fully traceable to the specific source and differ in the composition of the biomass fuel, e.g., in that the plant stalks and soil were also exposed to the fire. Nonetheless, when considering the benzene to toluene ratio (B/T), which is typically used to identify sources of VOC emissions but is also influenced by the underlying combustion conditions, 44 there is a trend toward more flaming combustion in the field compared to the laboratory, as indicated by B/T ratios of 5.7 and 1.3 for the field and laboratory samples, respectively.…”

Agricultural fires are a major source of biomass-burning organic aerosols (BBOAs) with impacts on health, the environment, and climate. In this study, globally relevant BBOA emissions from the combustion of sugar cane in both field and laboratory experiments were analyzed using comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry. The derived chemical fingerprints of fresh emissions were evaluated using targeted and nontargeted evaluation approaches. The open-field sugar cane burning experiments revealed the high chemical complexity of combustion emissions, including compounds derived from the pyrolysis of (hemi)cellulose, lignin, and further biomass, such as pyridine and oxime derivatives, methoxyphenols, and methoxybenzenes, as well as triterpenoids. In comparison, laboratory experiments could only partially model the complexity of real combustion events. Our results showed high variability between the conducted field and laboratory experiments, which we, among others, discuss in terms of differences in combustion conditions, fuel composition, and atmospheric processing. We conclude that both field and laboratory studies have their merits and should be applied complementarily. While field studies under real-world conditions are essential to assess the general impact on air quality, climate, and environment, laboratory studies are better suited to investigate specific emissions of different biomass types under controlled conditions.

“…Residential EFs were often measured in laboratory chambers or in simulated kitchens. − With an increasing number of field-based EFs available, it has been recognized that field-measured EFs are often different from laboratory measurements and are more applicable for emission inventory compilation. − EFs for individual pollutants can vary extensively because of differences in stove–fuel combinations. − ,,− Factors that determine EFs, such as the combustion efficiency, and operator behavior, such as ignition and fuel addition, , should be further explored. In addition to CO, SO 2 , PM, and BC, residential EFs of particulate chemical components, size segregated PMs, and volatile and intermediate volatile organic compounds are now available. − ,− ,− The use of solid fuels, especially biomass fuels, is not limited to the developing world but occurs also in the developed world. − For example, wood logs or pellets are used for space heating in Europe. − Because of the extensive variability, localized emission characterization is often important. In addition, EFs change dramatically during a single combustion event, , which is another important source of uncertainty that should be fully addressed in future studies.…”

Solid fuels used for cooking, heating, and lighting are major emission sources of many air pollutants, specifically PM2.5 and black carbon, resulting in adverse environmental and health impacts. At the same time, the transition from using residential solid fuels toward using cleaner energy sources can result in significant health benefits. Here, we briefly review recent research progress on the emissions of air pollutants from the residential sector and the impacts of emissions on ambient and indoor air quality, population exposure, and health consequences. The major challenges and future research priorities are identified and discussed.

In order to illustrate pollution characterization, source apportionment, and risk assessment of VOCs in Beijing, Baoding, and Shanghai, field observations of CO, NO, NO2, O3, and volatile organic compounds (VOCs) were conducted in 2019. Concentrations of VOCs were the highest in Beijing (105.4 ± 52.1 ppb), followed by Baoding (97.1 ± 47.5 ppb) and Shanghai (91.1 ± 41.3 ppb). Concentrations of VOCs were the highest in winter (120.3 ± 61.5 ppb) among the three seasons tested, followed by summer (98.1 + 50.8 ppb) and autumn (75.5 + 33.4 ppb). Alkenes were the most reactive VOC species in all cities, accounting for 56.0%, 53.7%, and 39.4% of ozone formation potential in Beijing, Baoding, and Shanghai, respectively. Alkenes and aromatics were the reactive species, particularly ethene, propene, 1,3,5-trimethylbenzene, and m/p-xylene. Vehicular exhaust was the principal source in all three cities, accounting for 27.0%, 30.4%, and 23.3% of VOCs in Beijing, Baoding, and Shanghai, respectively. Industrial manufacturing was the second largest source in Baoding (23.6%) and Shanghai (21.3%), and solvent utilization was the second largest source in Beijing (25.1%). The empirical kinetic modeling approach showed that O3 formation was limited by both VOCs and nitric oxides at Fangshan (the suburban site) and by VOCs at Xuhui (the urban site). Acrolein was the only substance with an average hazard quotient greater than 1, indicating significant non-carcinogenic risk. In Beijing, 1,2-dibromoethane had an R-value of 1.1 × 10−4 and posed a definite carcinogenic risk.
