Gas-phase tropospheric chemistry of organic compounds: A review
TL;DR: The current knowledge of the gas phase reactions occurring in the troposphere for alkanes, alkenes, alkynes, oxygenates and aromatic hydrocarbons and their photooxidation products is reviewed, and areas of uncertainty identified as mentioned in this paper.
Journal ArticleDOI
Volatile organic compounds (VOCs) in urban atmosphere of Hong Kong.
TL;DR: VOC concentrations in the winter were higher than those measured in the summer (winter to summer ratio > 1) and there is a necessity to tighten automobile emission standards in Hong Kong.
