Reactive processing of formaldehyde and acetaldehyde in aqueous aerosol mimics: Surface tension depression and secondary organic products
Surface tension depression and secondary organic products aqueous aerosol mimics
2011/9/2
The reactive uptake of carbonyl-containing volatile organic compounds (cVOCs) by aqueous atmospheric aerosols is a likely source of particulate organic material. The aque ous-phase secondary organic p...
Global atmospheric budget of acetaldehyde: 3-D model analysis and constraints from in-situ and satellite observations
Global atmospheric budget acetaldehyde 3-D model analysis and constraints in-situ and satellite observations
2010/8/12
We construct a global atmospheric budget for acetaldehyde using a 3-D model of atmospheric chemistry (GEOS-Chem), and use an ensemble of observations to evaluate present understanding of its sources a...
Acetaldehyde is a reactive intermediate in hydrocarbon oxidation. It is both emitted and taken up by snowpacks and photochemical and physical processes are probably involved. Understanding the reactiv...
Sources and sinks of acetone, methanol, and acetaldehyde in North Atlantic marine air
sinks acetone methanol acetaldehyde North Atlantic marine air
2009/2/12
Measurements of acetone, methanol, acetaldehyde and a range of non-methane hydrocarbons have been made in North Atlantic marine air at the Mace Head observatory. Under maritime conditions the combina...
Air-sea fluxes of methanol, acetone, acetaldehyde, isoprene and DMS from a Norwegian fjord following a phytoplankton bloom in a mesocosm experiment

The ocean's influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood. This work characterises the oceanic emission and/or uptake of methanol, acetone, acetaldehyde, isopre...
Plant physiological and environmental controls over the exchange of acetaldehyde between forest canopies and the atmosphere
physiological and environmental controls exchange forest canopies atmosphere
2010/1/18
We quantified fine scale sources and sinks of gas phase acetaldehyde in two forested ecosystems in the US. During the daytime, the upper canopy behaved as a net source while at lower heights, reduced ...
The effect of flooding on the exchange of the volatile C2-compounds ethanol,acetaldehyde and acetic acid between leaves of Amazonian floodplain tree species and the atmosphere

2010/1/18
The effect of root inundation on the leaf emissions of ethanol, acetaldehyde and acetic acid in relation to assimilation and transpiration was investigated with 2–3 years old tree seedlings of four Am...
Clay-Organic Molecule Interactions: Oxidation of Acetaldehyde by Montmorillonite in N2 Atmosphere at Room Temperature
Acetaldehyde Acetate Adsorption Montmorillonite Oxidation
2012/2/10
Oxidation of acetaldehyde molecules adsorbed on Na- and Mg-Wyoming montmorillonite at room temperature (20–25°C) and in N2 atmosphere has been studied by I.R. spectroscopy. A comparison between clay-a...
