Short summary
Volatile organic compounds drive atmospheric chemistry via oxidation, forming PM2.5/ozone precursors. This study introduces Vreact, a graph-based deep learning model predicting reaction rate constants (ki) for multiple oxidants simultaneously. It achieves mean squared error = 0.299 and R² = 0.941 for log10ki , overcoming single-oxidant model limits. Vreact advances pollutant formation insights and supports emission control strategies, aiding global air quality and public health efforts.

Short summary
This article comprehensively investigates the aqueous-phase OH oxidation of benzothiazoles (BTs), common rubber additives found in urban air, through laboratory simulation experiments. BTs can rapidly degrade, leading to light absorption, high yields of sulfate, and the formation of highly oxidized and/or oligomerized organic compounds. The results reveal that aqueous-phase BTs can contribute to secondary aerosols, altering the chemical and optical properties of atmospheric particles.

Short summary
This study investigated the role of nighttime chemistry during Chinese New Year's Eve that enhances the formation of nitrooxy organosulfates in the aerosol phase. Results show that anthropogenic precursors, together with biogenic ones, considerably contribute to the formation of low-volatility nitrooxy OSs. Our study provides detailed molecular composition of firework-related aerosols, which gives new insights into the physicochemical properties and potential health effects of urban aerosols.
