Abstract

Paulot et al. (Reports, 7 August 2009, p. 730) reported that the photooxidation of isoprene under low-nitrogen oxides (NOx) conditions produces epoxides that can facilitate the formation of secondary organic aerosol (SOA). However, another pathway involving the formation of methyl-butenediol intermediates can also lead to isoprene-derived SOA formation. Further research is needed to clarify the fate of isoprene in the atmosphere.

摘要

保罗等人（2009 年 8 月 7 日的报道，第 730 页）报告称，在低氮氧化物（NOx）条件下，异戊二烯的光氧化会产生环氧化物，从而促进二次有机气溶胶（SOA）的形成。然而，另一个涉及形成甲基丁烯二醇中间体的途径也可能导致异戊二烯衍生的 SOA 形成。需要进一步的研究来阐明异戊二烯在大气中的命运。
