While the major sinks for isocyanic acid (HNCO), a toxic atmospheric constituent emitted by biomass burning and catalytic converters in car engines, have been considered to be heterogeneous loss processes and dry deposition in the free troposphere, the role of Criegee intermediates remains underexplored. Here, using electronic structure calculations and kinetic simulations, the authors show that HNCO is highly reactive to stabilized Criegee intermediates in the atmosphere, discussing its potential role as sinks for HNCO.
