Reactions of NO sub(3) Radicals with Limonene and alpha -Pinene: Product and SOA Formation

Reactions of NO sub(3) radicals with limonene and alpha -pinene are investigated. Monoterpenes are ubiquitous in forested environments and are subject to reactions with OH radicals, NO sub(3) radicals, and O sub(3) both within and above forest canopies. While reactions of monoterpenes with OH and O...

Description
Summary:Reactions of NO sub(3) radicals with limonene and alpha -pinene are investigated. Monoterpenes are ubiquitous in forested environments and are subject to reactions with OH radicals, NO sub(3) radicals, and O sub(3) both within and above forest canopies. While reactions of monoterpenes with OH and O sub(3) have received considerable attention with regard to their reaction kinetics, reaction products and secondary organic aerosol (SOA) formation those with NO sub(3) have received relatively little consideration. To redress this imbalance and to try and assess the possible importance of NO sub(3) + monterpene reactions within forest canopies investigations are performed on selected monterpenes. The products and aerosol formation from the NO sub(3) radical initiated oxidation of limonene and alpha -pinene are investigated. The possible pathways leading to SOA formation and also their potential importance are also discussed based on laboratory results on the reaction of NO sub(3) with the two major products.
