Summary: The prohibition of open straw burning and clean energy transitions in the last 10 years has led to significant reductions in ambient biomass burning pollution in Beijing. Research shows that the concentration of the biomass burning molecular tracer (levoglucosan) has decreased based on filter sample results collected in Beijing during 2010-2011 and 2017-2018.

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: 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: 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: 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: Biomass burning activities in northern China, with a focus on rural areas, show higher levels of carbonaceous components and biomass burning tracers at night compared to daytime. However, secondary inorganic ions are enhanced during the day. An episode of intense biomass burning pollution was observed at the end of October 2016, with notably high levels of levoglucosan. The study suggests that biomass combustion primarily affects carbonaceous components, rather than secondary inorganic aerosols in the ambient air. Additionally, the levoglucosan / mannosan ratios remained high during different biomass burning pollution periods, but the levoglucosan / K+ ratio was significantly elevated during the period of intense biomass burning pollution.

Summary: Through experiments and observations, it was found that under dry conditions, biomass burning aerosols (BBA) are in a non-solid state, differing from secondary organic aerosols (SOA). This suggests that under dry conditions, the diffusion coefficient of gaseous molecules in BBA may be much higher than in SOA.

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.
