“…An experiment with birch seedlings growing intermixed with Rhododendron tomentosum gave strong evidence for the possibility of the absorbance and re-release of biogenic terpenes to neighboring plants [Himanen et al, 2010]. In general, BVOC exchange is known to be compound specific [Kesselmeier and Staudt, 1999]. It is therefore likely that ecosystems not emitting certain compounds may nevertheless act as sinks for these species.…”

Deposition fluxes of terpenes over grassland

et al. 2011

[1] Eddy covariance flux measurements were carried out for two subsequent vegetation periods above a temperate mountain grassland in an alpine valley using a proton-transfer-reaction-mass spectrometer (PTR-MS) and a PTR time-of-flight-mass spectrometer (PTR-TOF). In 2008 and during the first half of the vegetation period 2009 the volume mixing ratios (VMRs) for the sum of monoterpenes (MTs) were typically well below 1 ppbv and neither MT emission nor deposition was observed. After a hailstorm in July 2009 an order of magnitude higher amount of terpenes was transported to the site from nearby coniferous forests causing elevated VMRs. As a consequence, deposition fluxes of terpenes to the grassland, which continued over a time period of several weeks without significant reemission, were observed. For days without precipitation the deposition occurred at velocities close to the aerodynamic limit. In addition to monoterpene uptake, deposition fluxes of the sum of sesquiterpenes (SQTs) and the sum of oxygenated terpenes (OTs) were detected. Considering an entire growing season for the grassland (i.e., 1 April to 1 November 2009), the cumulative carbon deposition of monoterpenes reached 276 mg C m −2 . This is comparable to the net carbon emission of methanol (329 mg C m −2 ), which is the dominant nonmethane volatile organic compound (VOC) emitted from this site, during the same time period. It is suggested that deposition of monoterpenes to terrestrial ecosystems could play a more significant role in the reactive carbon budget than previously assumed.

“…On a global scale, the extensive anthropogenic use of terpenes and terpenoids associated with their natural emissions from coniferous forests, are one of the principal sources of biogenic volatile organic compounds (BVOC) [11][12][13]. About half of global BVOC-emissions originate in isoprene, the terpenes building-block [14], and their role in aerosol formation became an important research topic on the chemistry of the atmosphere, with a renewed emphasis due to the ongoing climate change debate [12,15,16].…”

Terpenes and terpenoids belong to the largest and most diverse class of natural products. Due to the increasing importance of their applications and the emerging perception of their impact on the environment, the available physico-chemical characterization is insufficient. In this work the water solubility of geraniol, linalool, DL-citronellol, thymol, eugenol, carvacrol and p-cymene, in the temperature range from (298.15 to 323.15) K, and at atmospheric pressure, is studied. Due to the low solubility of these compounds a novel technique was adopted for their measurements and validated using the aqueous solubility data for sparingly soluble aromatic compounds. The thermodynamic properties of solution were derived from the experimental data at infinite dilution. It is shown that the solubility of terpenes in water is an endothermic process confirming the existence of UCST phase diagrams, and only for carvacrol and eugenol is entropically driven. The experimental information is shown in a two-dimensional chemical space diagram providing indications to their probable distribution in the environment once released.

“…Many tree species produce monoterpenes (C 10 H 16 ), a diverse class of volatile terpenoids, which can be emitted into the atmosphere at high rates [Kesselmeier and Staudt, 1999;Fuentes et al, 2000]. Within ecosystems, monoterpenes mediate plant-microbe [Dorman and Deans, 2000] and plant-insect [Beyaert and Hilker, 2014] interactions and protect photosynthesis during abiotic stress [Peñuelas and Llusià, 2002;Vickers et al, 2009].…”

Despite orders of magnitude difference in atmospheric reactivity and great diversity in biological functioning, little is known about monoterpene speciation in tropical forests. Here we report vertically resolved ambient air mixing ratios for 12 monoterpenes in a central Amazon rainforest including observations of the highly reactive cis-β-ocimene (160 ppt), trans-β-ocimene (79 ppt), and terpinolene (32 ppt) which accounted for an estimated 21% of total monoterpene composition yet 55% of the upper canopy monoterpene ozonolysis rate. All 12 monoterpenes showed a mixing ratio peak in the upper canopy, with three demonstrating subcanopy peaks in 7 of 11 profiles. Leaf level emissions of highly reactive monoterpenes accounted for up to 1.9% of photosynthesis confirming light-dependent emissions across several Amazon tree genera. These results suggest that highly reactive monoterpenes play important antioxidant roles during photosynthesis in plants and serve as near-canopy sources of secondary organic aerosol precursors through atmospheric photooxidation via ozonolysis.
