Summary: The study investigated the evolution of plumes from wood burning in real atmospheric conditions, finding that smoldering plumes produce secondary organic aerosols at a faster rate compared to flaming plumes, with a higher oxygen-to-carbon ratio. Flaming plumes had higher emissions of black carbon and NOx, while smoldering plumes were dominated by organic aerosol and had lower NOx emissions, resulting in contrasting trends in the oxidation of organic aerosols.

Summary: Carbonaceous aerosol is a dominant component of fine particles in Beijing. A newly developed method combining C-14 and organic tracers was applied to trace its sources, with findings showing higher fossil-derived OC in urban areas and a decrease in fossil carbon ratio in summer due to less coal consumption. Non-fossil fractions of secondary organic carbon increased in summer, with a larger biogenic component contributing. Comparisons with a chemical mass balance model yielded generally good results, except for cooking aerosol.

Summary: This study investigates the air pollution problem caused by residential wood heating in Temuco, a city in Southern Chile. The concentrations of PM2.5, levoglucosan, and K-sol were found to be particularly high in winter. The ratios of levoglucosan and K-sol to PM2.5 were lower in summer. Spatial clustering analysis revealed that some neighborhoods with higher ratios were associated with lower socioeconomic status and possibly lower quality stoves.

Summary: Biomass burning is an important source of carbonaceous aerosols in Northeast China. During the sampling period, autumn and winter had higher biomass burning activities, and burning of crop residues was the dominant source of biomass burning aerosols. Moreover, the relative contribution of biomass burning to organic carbon would be underestimated without considering the degradation effects of levoglucosan.

Summary: Residential heating with solid fuels, especially coal, contributes to poor air quality in Central and Eastern Europe. This study analyzed emissions from a single-room heater burning brown coal briquettes and spruce logs, focusing on the presence of inorganic, aromatic, and organic constituents. It was found that emissions from brown coal briquettes combustion were a significant source of levoglucosan, a biomass burning marker, and exhibited defunctionalization and desubstitution characteristics in the emitted polycyclic aromatic hydrocarbons. The study also used the concept of island and archipelago structural motifs to describe the fraction of low-volatile organic compounds in particulate emissions, revealing different patterns between brown coal briquette and spruce logwood combustion.

Summary: This study aims to gather experimental data on the combustion behavior of single wood particles under oxyfuel conditions. The focus is to understand how the application of oxyfuel technology affects the conditions in fuel beds and provide data for simulations. Combustion experiments were conducted on spherical particles of different sizes with varying oxygen concentrations in different atmospheres. The results showed that combustion times were generally shorter under oxyfuel conditions compared to air conditions, and increasing oxygen concentration further reduced combustion durations. The temperatures of the flame and the particles increased with higher oxygen concentration, with smaller particles showing higher values. Steam concentration had a varying effect on temperatures.

Summary: In a coal mining area in northern Colombia, variations in OC and EC concentrations in PM10 were observed throughout different seasons, with the highest concentrations occurring during the transition period between the dry and wet seasons. Strong correlations between OC and EC during this transition season suggest a common primary combustion source. High concentrations of OC and EC were associated with low wind speeds moving in different directions. Atmospheric aerosol pollutants in the mining area were mainly attributed to regional atmospheric transport from industrial areas and biomass burning sites in Venezuela.

Summary: This study investigated the concentrations and characteristics of carbonaceous aerosols and inorganic species in a mountainous city in Greece. It found high concentrations of organic carbon and levoglucosan in winter, with a high proportion of water-soluble organic carbon potentially formed from fast oxidation processes. Using a levoglucosan tracer method, the study estimated high contributions of biomass burning to organic carbon in winter. In summer, the levels of carbonaceous components were low, with a higher proportion of water-soluble organic carbon.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
