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: 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: The chemical composition of PM2.5 was monitored in Hanoi, Vietnam from August 2019 to July 2020. The annual average PM2.5 concentrations exceeded national and WHO limit values. Winter had the highest daily PM2.5 concentrations due to stagnant meteorological conditions. Organic matter, biomass burning, secondary inorganic aerosol, and coal combustion were identified as significant sources of PM2.5 pollution. Zinc was the most common trace element and often appeared with Cd, Cl-, and Pb, indicating industrial sources and/or coal combustion. Positive matrix factorization identified six main source factors: traffic, local secondary inorganic aerosol, biomass burning, industry, long-range transported SIA, and dust.

Summary: This study investigates the effects of moisture content (MC) on the emission characteristics of organic compounds during wood combustion. The results show that MC significantly influences the emission factors of organic compounds. The composition of organic compounds is also influenced by MC and ignition temperature, with different profiles observed at various MCs and increasing temperature.

Summary: In a residential area in southeastern Spain, the composition of PM10, including molecular markers of biomass burning, was determined during winter and early spring. Biomass combustion was found to contribute 23% to organic carbon, with levoglucosan being the dominant anhydrosugar. Positive Matrix Factorization model identified six factors contributing to PM10 composition, with biomass burning factor accounting for 8%.

Summary: This study investigates the impact of ozone (O3) on sugarcane production in Brazil, a major producer of biofuels. The results show that current O3 exposure leads to a loss of 5.6% to 18.3% in total crop productivity in the region. The susceptibility of different sugarcane genotypes to O3 plays a critical role in determining the extent of the impact. The study highlights the urgent need to understand the effects of O3 on this important bioenergy crop and its potential implications for tropical food production.

Summary: Ambient outdoor air pollution is a significant risk factor for health issues and mortality, especially in LMICs. Small-scale burning activities play a crucial role in local pollutant emissions, but research on interventions to address this issue is lacking. Existing literature highlights the need for further research on effective interventions targeting individual-initiated burning practices.

Summary: This study discusses the impacts of small-scale biomass burning on air quality in urban and suburban areas of central Japan, showing that in fall BB is a significant source of PM2.5, organic carbon, and elemental carbon. High concentrations of levoglucosan were observed at both suburban and urban sites, with air masses transported from Northeast China influencing levoglucosan levels. Local or regional BB emissions were prevalent at most sites, with urban sites near farmland showing higher BB contributions to PM2.5 in fall and winter.

Summary: This study investigated the contribution of biomass burning to atmospheric particulate matter in the Tibetan Plateau. The results showed that biomass burning tracers were highly concentrated in high altitude areas, with the highest concentrations observed in the northeastern and southwestern regions. Local emissions were found to be an important contributor in these areas. This study improves our understanding of biomass burning characteristics and effects in the Tibetan Plateau.

Summary: This study focuses on the impact of agricultural field burning on air pollution in rural communities in the United States. It finds that smoke from agricultural burning contains air toxics that negatively affect respiratory health. The study uses questionnaire data from 735 students and finds a relationship between agricultural burning and respiratory symptoms in children.

Summary: This study investigates the extreme fire season, factors promoting extreme fire weather, and heavy air pollution caused by biomass burning in Yakutia, Eastern Siberia. The results show that the 2021 fire season in Yakutia was the worst in the past four decades, with a significant increase in the number of hotspots and adverse weather conditions. The intensification of wildfires during August 2021 was attributed to persistent high-pressure systems and low wind speeds, resulting in the accumulation of wildfire emissions and a significant impact on air quality in the region.

Summary: This study measured the isotopic signatures of PM2.5 and size-segregated particles emitted from incense stick and cigarette burning for pollution source identification. The results showed that the isotopic values from incense stick burning were heavier than cigarette burning, and there were differences in 813C values between PM2.5 and size-segregated particles. However, the analysis of 815N in size-segregated particles was limited for pollution source identification of different particle sizes.

Summary: The article investigates the oxidative potential of PM2.5 in an urban area in São Paulo, Brazil, focusing on its chemical composition and sources. The study finds that Humic-Like Substances (HULIS) are the major carriers of oxidative potential, while vehicular and industrial emissions contribute significantly to the oxidative potential of PM2.5. These findings provide important insights for developing air quality control strategies to protect human health.

Summary: This study investigates vehicle emissions in the Metropolitan Area of Sa & SIM;o Paulo (MASP) and calculates the emission factors (EFs) for heavy-duty and light-duty vehicles (HDVs and LDVs) using tunnel measurements. The results suggest that the vehicular emissions control policies implemented in Brazil have been effective in reducing emissions. Higher copper emissions were observed for LDVs, possibly due to the increased use of ethanol fuel in the region. Zinc and lead emissions from HDVs were associated with lubricating oil emissions from diesel vehicles.
