Short summary
HNCO is a toxic molecule and can cause cardiovascular and cataract problems through protein carbamylation once inhaled. Recently reported ambient measurements of HNCO in North America raise concerns for human exposure. To better understand HNCO's loss processes and behaviour in the atmosphere, we provide thermochemical data on HNCO. The parameters allow for more accurate predictions of its lifetime in the atmosphere and consequently help define exposure of this toxic molecule.
