Summary report: Photo-oxidation of methylamine, dimethylamine and trimethylamine. CLIMIT project no. 201604."},"content":{"rendered":"<p class=\"wp-block-paragraph\">The atmospheric gas phase photo-oxidation of methylamine (CH3NH2), dimethylamine ((CH3)2NH) and trimethylamine ((CH3)3N) has been studied under pseudo natural conditions at the European Photochemical Reactor, EUPHORE, in Valencia, Spain. Major products in the photo-oxidation were imines (methanimine and N-methyl-methanimine) and amides (formamide, N-methyl formamide and N,N-dimethyl formamide). Total aerosol yields obtained in EUPHORE experiments were between 8 and 14%. Mimicking conditions at Mongstad results in a steady-state nitrosamine concentration of less than 0.6 % of photo-oxidized dimethylamine and less than 1.1 % of photo-oxidized trimethylamine. For rural regions it is predicted that the formation yield of the corresponding nitramine in the atmospheric oxidation of CH3NH2, (CH3)2NH and (CH3)3N is less than 0.4 %, 2.5 % and 5 %, respectively. The major uncertainties in the current understanding of the fate of amines emitted to the atmosphere are related to night-time chemistry, to the chemistry of imines, and to chemistry in the aqueous aerosol.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 15:01:44","footnotes":""},"nva_tax_category":[1095],"class_list":["post-119923","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-report"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/119923","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/119923\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=119923"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=119923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
