PANs in the atmosphere
Technical Report
·
OSTI ID:5674112
The types of peroxyacetyl nitrates (PANs) and peroxybenzyl nitrates (PBzNs) present or possibly present in the ambient atmosphere are discussed. Biological activities of the PANs and PBzNs are briefly considered. The concentration and composition of PANs in the atmosphere are discussed and calculations made of the production of RCO radicals from precursor alkanes, alkenes and aromatic hydrocarbons present in the atmosphere. Lifetimes of PANs are estimated, and the effects of transport on the composition of PANs has been evaluated.
