Uptake of Methacrolein and Methyl Vinyl Ketone by Tree Saplings and Implications for Forest Atmosphere

TLDR
The loss rate by tree uptake was the highest, followed by the reaction with OH radicals, even at a high OH concentration, suggesting that tree uptake provides a significant sink for the two isoprene-oxygenates within the forest canopy.Abstract:
Methacrolein (MACR) and methyl vinyl ketone (MVK) are oxygenates produced from isoprene which is abundantly emitted by trees. The uptake rate of these compounds by leaves of three different Quercus...read more

Bidirectional exchange of biogenic volatiles with vegetation: emission sources, reactions, breakdown and deposition.
TL;DR: It is argued that future models should be based upon the concept of bidirectional BV OC exchange and consider modification of BVOC sink/source strengths by within-leaf metabolism and storage.

Within-plant isoprene oxidation confirmed by direct emissions of oxidation products methyl vinyl ketone and methacrolein
Kolby J. Jardine,Russell K. Monson,Leif Abrell,Scott R. Saleska,Almut Arneth,Angela Jardine,Françoise Yoko Ishida,Ana Maria Yanez Serrano,Paulo Artaxo,Thomas Karl,Silvano Fares,Allen H. Goldstein,Francesco Loreto,Travis E. Huxman +13 more
TL;DR: In this article, the authors used pyruvate-2-13 C leaf and branch feeding and individual branch and whole mesocosm flux studies to infer that isoprene is oxidized to methyl vinyl ketone and methacrolein in leaves and that iox/i emission ratios increase with temperature.
Journal ArticleDOI
Heterogeneous reactions of volatile organic compounds in the atmosphere
TL;DR: In this paper, the authors present the first specific review for the progress of heterogeneous reaction studies on VOCs, including carbonyl compounds, organic acids, alcohols, and so on.

TL;DR: How a combination of the enhanced phytoremediation capacity of plants together with cutting-edge air-cleaning and smart sensor technologies can improve indoor life while reducing energy consumption is discussed.
Journal ArticleDOI
Plant volatiles as cues and signals in plant communication.
TL;DR: This review synthesises the recent progress made in understanding the role of plant volatiles as mediators of plant interactions at the individual and community levels, highlighting the complexity of the plant receiver response to diverse volatile cues and signals and addressing how specific responses shape plant growth and survival.

Higher plant metabolism of xenobiotics: the 'green liver' concept.
TL;DR: Xenobiotic metabolism in plants resembles that in animal liver on the levels of metabolite patterns, enzyme classes and cDNA sequences as discussed by the authors, and the evidence for the 'green liver' concept of xenobiotic plant metabolism is presented.

A product study of the gas-phase reaction of Isoprene with the OH radical in the presence of NOx
Ernesto C. Tuazon,Roger Atkinson +1 more
TL;DR: In this article, the gas phase reaction of isoprene with the OH radical, in the resence of NOx, was investigated at 298 ± 2 K and atmospheric pressure of air by long path length FT-IR spectroscopy.

The application of proton transfer reaction-mass spectrometry (PTR-MS) to the monitoring and analysis of volatile organic compounds in the atmosphere
TL;DR: The principles of operation of the PTR-MS are described, its advantages and disadvantages discussed, its inherent uncertainties highlighted, some of its uses in atmospheric sciences reviewed, and some suggestions made on its future application to atmospheric chemistry.

Isoprene and its oxidation products, methyl vinyl ketone and methacrolein, in the rural troposphere
TL;DR: The mixing ratios of methyl vinyl ketone and methacrolein were measured at a site located in the Kinterbish Wildlife Management Area in western Alabama between June 15 and July 20, 1990.
