Summary: This paper provides a comprehensive characterization of diesel Particulate Matter (PM) in terms of various factors, including mass, chemical composition, particles number, size distribution, and mutagenic potential. The study found that different fuel blends in a diesel engine can result in variations in the chemical composition and toxicity of PM. Biofuel blends showed negligible differences in particles number distributions compared to standard diesel, but had an impact on the mutagenic potential of PM samples.

Summary: Emission of organic aerosol from wood combustion is a deterministic process influenced by factors such as pyrolysis reactions, temperature, moisture content, and wood type. Higher temperatures increase the mass loss rate and the concentration of released gases and particles, while larger wood size results in lower particle yield due to higher mass transfer resistance.

Summary: Pyrolysis and combustion experiments were conducted on two commonly used facemasks in Russia, and the by-products and gaseous emissions were analyzed. The results indicate that both masks undergo thermal decomposition and combustion mainly between 200 and 500 degrees Celsius. Significant differences were observed in the experimental results of the two masks due to the different fiber materials used.

Summary: In order to relieve the pressure on forests in Europe, lower quality woody materials, wastes, and agricultural fuels are being used for heat production. The use of these fuels poses challenges related to chemical composition variability and fuel characteristics. This study investigated the performance of a small-scale biomass heating boiler fired with wood pellets and two biomass-based insulation materials under standard conditions. The emissions and efficiency of the boiler were evaluated, and the results were compared to legal limits. Blending wood fibers with certified wood is necessary to meet emissions regulations. Particulate and gaseous emissions were reduced through the blending of different fuel types. The findings suggest that pelletized biomass-based insulation materials mixed with certified wood have potential as alternative fuels for residential biomass boilers.

Summary: Through experimental research on a single-cylinder diesel engine comparing a lateral swirl combustion system (LSCS) and a Turbocharger-Charge Air Cooling-Diesel Particle Filter Series combustion system (TCDCS) at different conditions, it was found that the LSCS exhibits better combustion performance and lower total particle emission characteristics compared to the TCDCS. The LSCS effectively reduces the particle number and mass concentrations by 8.7-62.4% and 15.2-55.6% respectively at various loads. The increase in particle concentration smaller than approximately 8 nm in the LSCS can be attributed to the higher temperature and more thorough fuel/air mixture.

Summary: In this study, direct emissions of particulate Gly and Mgly from different residential fuels used in north China were reported. The emission ratios and emission factors of particulate Gly and Mgly for biomass burning were higher than those for coal combustion. The difference in emissions could be attributed to the different combustion processes influenced by fuel types and combustion conditions. The results suggest the importance of considering direct emissions from emission sources when estimating the formation of SOA from Gly and Mgly.
