Short summary
Isocyanic acid, HNCO, is a toxic chemical compound emitted to the atmosphere by biomass burning and by unwanted release in NOx mitigation systems in vehicles such as the AdBlue system. We have studied the loss processes of HNCO, finding that it is unreactive to most atmospheric oxidants and thus has a long chemical lifetime. The main removal is then by deposition on surfaces and transition to aqueous phase, such as clouds. The long lifetime also allows it to be transported to the stratosphere.
