Iron-Facilitated Organic Radical Formation from Secondary Organic Aerosols in Surrogate Lung Fluid

Jinlai Wei et al.

Summary: This study reveals that the deposition of fine particles and iron in the respiratory system can generate organic radicals in surrogate lungfluid (SLF). Iron ions significantly enhance the yield of organic radicals by facilitating the decomposition of organic peroxides. Ascorbate mediates the redox cycling of iron ions to sustain the decomposition of organic peroxides. In addition, antioxidants are efficient at scavenging hydroxyl radicals and superoxide.

Molecular Analysis of Secondary Brown Carbon Produced from the Photooxidation of Naphthalene

Kyla Siemens et al.

Summary: This study investigates the chemical composition of organic light-absorbing components in anthropogenic secondary organic aerosol. The results provide molecular-level insights into their composition and optical properties, revealing the formation and degradation of strongly absorbing nitro-aromatic chromophores under high-NOx conditions. The addition of NOx enhances the light absorption of the aerosol and reduces its wavelength-dependence. The identification of specific molecular chromophores suggests their potential use as markers for BrC related to anthropogenic emissions.

Effects of Acidity on Reactive Oxygen Species Formation from Secondary Organic Aerosols

Jinlai Wei et al.

Summary: Acidity has significant effects on the formation of reactive oxygen species (ROS) in atmospheric secondary organic aerosols (SOA). Different pH values result in distinct radical yields and composition in SOA. Isoprene SOA has higher radical yields at neutral pH, while superoxide is the dominant species at lower pH. Acidic conditions can suppress the decomposition of organic peroxide and enhance the molar yields of hydrogen peroxide (H2O2) in biogenic and aromatic SOA.

Superoxide Formation from Aqueous Reactions of Biogenic Secondary Organic Aerosols

Jinlai Wei et al.

Summary: The study demonstrates the dominant formation of superoxide (O2•−) in the aqueous reactions of biogenic SOA generated by photooxidation, with a molar yield of 0.01-0.03%. Kinetic modeling reveals the relationship between the relative yields of various types of ROS and the abundance of organic hydroperoxides and alcohols in SOA.

Coexistence of three liquid phases in individual atmospheric aerosol particles

Yuanzhou Huang et al.

Summary: Individual atmospheric particles can contain mixtures of primary organic aerosol (POA), secondary organic aerosol (SOA), and secondary inorganic aerosol (SIA), with the potential to have three distinct liquid phases. The presence of these phases is influenced by the elemental oxygen-to-carbon (O:C) ratio of the SOA, impacting equilibration timescales and potential effects on cloud formation and atmospheric chemistry.

Estimation of secondary organic aerosol viscosity from explicit modeling of gas-phase oxidation of isoprene and α-pinene

Tommaso Galeazzo et al.

Summary: This study utilized the GECKO-A model to conduct explicit chemical modeling of SOA formation, investigating the effects of chemical composition, relative humidity, and other factors on particle viscosity. The simulation results showed good agreement with measurements for isoprene SOA viscosity, while underestimating the viscosity of ff-pinene SOA. The study suggests that missing processes in the model and kinetic limitations may play a role in enhancing particle viscosity.

Viscosity and liquid-liquid phase separation in healthy and stressed plant SOA

Natalie R. Smith et al.

Summary: This study investigated the molecular composition, viscosity, and liquid-liquid phase separation of secondary organic aerosol (SOA) derived from synthetic mixtures of volatile organic compounds (VOCs) representing emission profiles for Scots pine trees under healthy and aphid-herbivory stress conditions. The results showed that stressed plant SOA exhibited phase separation over a broader humidity range than healthy plant SOA, with higher viscosity and increased abundance of higher molecular weight species. Additionally, the study highlighted the importance of studying properties of SOA generated from realistic multi-component VOC mixtures.

Peroxy radical kinetics and new particle formation

Meredith Schervish et al.

Summary: Experimental results show that the RO2 to HO2 ratio and the uncertain RO2 cross reaction kinetics have a significant impact on the formation of dimers in the process of new particle formation. The sensitivity of the results to the RO2 rate coefficients and RO2:HO2 suggests caution in extrapolating low-NOx chamber results to the atmosphere. The atmosphere's sensitivity to the specific mixture of organic compounds and peroxy radicals highlights the need for further research into the effects of these factors.

Effect of aromatic ring substituents on the ability of catechol to produce brown carbon in iron(iii)-catalyzed reactions

Henry Chin et al.

Summary: The study demonstrates that reactions between Fe(iii) and various precursors under pH = 3 conditions can lead to the formation of highly insoluble and strongly light-absorbing organic particles. The Fe(iii)-catalyzed chemistry plays a significant role in the aging of atmospheric aerosols from biomass burning, particularly in enhancing the light-absorbing properties of aerosol particles.
