Summary: Controlling the reactivity of diaryl carbenes can be achieved by manipulating the electronic properties of the substituents, allowing for highly chemoselective carbene transfer reactions without the need for external additives. Photolysis of diazo compounds can readily access the free diaryl carbenes, which can then undergo various chemoselective reactions. Experimental and theoretical analyses confirm the involvement of different carbene spin states in rationalizing the observed reactivity.

Summary: The study investigated the photochemical characteristics of EPS from different microbial sources, revealing that the diversity of EPS composition led to variations in the steady-state concentrations of reactive species. Protein-like components in EPS were found to undergo degradation under light exposure, while humic-like components remained stable. The phototransformation of EPS facilitated the degradation of antibiotic tetracycline.

Summary: In this study, it was found that decreasing the diameter of microdroplets significantly increases the reaction rate of dye oxidation using Fe(III)-oxalate photochemistry and g-C3N4 photocatalysis. This rate increase is attributed to the change in interface properties of microdroplets. The results of this study have important implications for improving the efficiencies of photochemistry and photocatalysis, as well as atmospheric photochemistry.

Summary: Online detection of bioaerosols based on the light-induced fluorescence (LIF) technique is still challenging, but this study provides insights into the sources of fluorescent aerosol particles (FAP) in the ambient atmosphere. Fungal spores and pollen are widely observed in all types of FAP, while bacteria are associated with fine mode FAP. FL-B and -BC particles, which contribute the most to FAP, are strongly associated with various nonbiological compositions.

Summary: This study investigates the influence of Criegee chemistry on the formation and growth processes as well as chemical compositions of secondary organic aerosol (SOA) through quantum chemical and kinetics modeling methods. The results reveal that the addition reactions of stabilized Criegee intermediates (SCIs) with hydroperoxide esters proceed through successive insertion of SCIs to form oligomers. The barrier heights and exothermicity of the oligomerization reactions are found to be dependent on the number of methyl substituents. Additionally, the rate coefficients of the reactions between SCIs and hydroperoxymethyl formate (HPMF) are influenced by the position of the methyl substituent.

Summary: This study investigated the photo reactivity of Ferric oxalate (Fe(III)-Ox) complex in atmospheric particles using Raman spectroscopy. It was found that the concentration of photoproduct Fe(II)-Ox was higher at the surface and inside of the droplets compared to bulk solution. Despite hindering the Fenton intermediate reaction, FeCO3, the photolysis rate of Fe(III)-Ox in droplets was significantly faster than in bulk solution. The mechanism and kinetics of Fe(III)-Ox photolysis varied between the aqueous/gas interface, inside of droplets, and bulk solution, leading to an underestimation of oxide species production from atmospheric Fe(III)-Ox droplets.

Summary: Bromoform (CHBr3) is an important precursor of reactive bromine species in the troposphere and stratosphere. Previous models have only considered natural production of CHBr3 from marine organisms, but this study finds significantly higher levels of CHBr3 in water and air due to anthropogenic sources in an industrialized area. These findings suggest that industrial discharges may be an important missing factor in estimates of organic bromine flux to the atmosphere.

The H2O2 system showed higher degradation efficiency (91.0%) compared to the PS system (52.4%) under the same experimental condition. CAT concentration influenced ATL degradation in the H2O2 system, while the optimal CAT concentration in the PS system was 5 μM. Both systems reduced luminescent bacteria inhibition rates by approximately 25%.

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.
