“…Among polymers, physico-chemical properties for VOC system construction are generally suitable for rigid polymers with low amorphous phase (high crystalline phase) fraction such as fluorinated hydrocarbons -PFA (perfluoroalkoxy), FEP (fluorinated ethylene propylen), and PTFE brands (e.g. Teflon ® and Chemfluor ® ) (Geosyntec consultants Inc. For gas exchange enclosures (cuvettes), glass, although fragile, typically has very low adsorption capacity for most VOCs and therefore has been used in many sampling systems (Beauchamp et al, 2005;Copolovici et al, 2011;Copolovici and Niinemets, 2010;Fuentes et al, 1995;Hüve et al, 2007;Matsunaga et al, 2008;Papiez et al, 2009;Rasulov et al, 2009a;Wildt et al, 2003).

Abstract. The capacity for volatile isoprenoid production under standardized environmental conditions at a certain time (E S , the emission factor) is a key characteristic in constructing isoprenoid emission inventories. However, there is large variation in published E S estimates for any given species partly driven by dynamic modifications in E S due to acclimation and stress responses. Here we review additional sources of variation in E S estimates that are due to measurement and analytical techniques and calculation and averaging procedures, and demonstrate that estimations of E S critically depend on applied experimental protocols and on data processing and reporting. A great variety of experimental setups has been used in the past, contributing to study-toCorrespondence to:Ü. Niinemets (ylo.niinemets@emu.ee) study variations in E S estimates. We suggest that past experimental data should be distributed into broad quality classes depending on whether the data can or cannot be considered quantitative based on rigorous experimental standards. Apart from analytical issues, the accuracy of E S values is strongly driven by extrapolation and integration errors introduced during data processing. Additional sources of error, especially in meta-database construction, can further arise from inconsistent use of units and expression bases of E S . We propose a standardized experimental protocol for BVOC estimations and highlight basic meta-information that we strongly recommend to report with any E S measurement. We conclude that standardization of experimental and calculation protocols and critical examination of past reports is essential for development of accurate emission factor databases.

“…To investigate the impact of BVOCs on air quality and pollution, atmospheric BVOCs have been one of the most discussed topics in atmospheric chemistry in recent decades. Contributions of BVOCs to photochemical oxidants (Papiez et al, 2009) and SOAs (Henze and Seinfeld, 2006), observations and estimation of emission factors of BVOCs such as isoprene and monoterpenes (Guenther et al, 1995(Guenther et al, , 1996Tani et al, 2002;Guenther et al, 2006), and laboratory experiments to establish the mechanisms of SOA formation from BVOCs (Claeys et al, 2004;Perraud et al, 2010;Surratt et al, 2010) have all been investigated.…”

A new system that uses the total reactivity with ozone (R O3 ) was developed for measuring biogenic volatile organic compounds (BVOCs) emitted from vegetation into the atmosphere. The decrease in ozone caused by the reaction with VOCs was monitored at the ppbv level by dual chemiluminescence detectors (CLDs) based on the NO-O 3 reaction. Ozone was monitored by the dual CLDs before and after the reactor to correct for fluctuations in the ozone concentration. Such dual detectors can remove the interference caused by water vapor. A glass double-tube was adopted as the reactor. The loss rate of ozone to the wall was typically (6 ± 3) × 10 -4 s -1 . Gaseous cyclohexane was also added to the sample before it was introduced into the reactor to scavenge secondary OH radicals. From the characterization of the R O3 analyzer using the standard VOC sample, the dependence of ozone reduction on the reaction time and reactivity were shown to agree with theoretical predictions. A calibration procedure for determining the reaction time was also established. Consequently, the detection limit for R O3 in a 57-s reaction was determined to be 1.4 × 10 -4 s -1 (S/N = 3), which corresponded to 27 ppbv of limonene. It was confirmed that the R O3 analyzer was capable of measuring BVOC levels. Finally, a practical trial was conducted in which BVOCs emitted from a real needle-leaf tree were monitored. BVOC emissions from the tree were detected and a significant increase in R O3 was observed when the tree was irradiated with light.

Emission of sunscreen salicylic esters from desert vegetation and their contribution to aerosol formation

Abstract. Biogenic volatile organic compounds (BVOC) produced by plants are known to have an important role in atmospheric chemistry. However, our knowledge of the range of BVOCs produced by different plant processes is still expanding, and there remain poorly understood categories of BVOCs. In this study, emissions of a novel class of BVOC emissions were investigated in a desert region. Our study considered 8 species of common desert plants: blackbrush (Coleogyne ramosissima), desert willow (Chilopsis linearis), mesquite (Prosopis glandulosa), mondel pine (Pinus eldarica), pinyon pine (Pinus monophylla), cottonwood (Populus deltoides), saguaro cactus (Carnegiea gigantea) and yucca (Yucca baccata). The measurements focused on BVOCs with relatively high molecular weight (>C 15 ) and/or an oxygenated functional group. Significantly high emission rates of two salicylic esters were found for blackbrush, desert willow and mesquite with emission rates of 3.1, 1.0 and 4.8µgC dwg −1 h −1 , respectively (dwg; dry weight of the leaves in gram). The salicylic esters were identified as 2-ethylhexenyl salicylate (2-EHS) and 3,3,5-trimethylcyclohexenyl salicylate (homosalate) and are known as effective ultraviolet (UV) absorbers. We propose that the plants derive a protective benefit against UV radiation from the salicylic esters and that the emission process is driven by the physical evaporation of the salicylic esters due to the high ambient temperatures. In addition, the salicylic esters are predicted to be an effective precursor of secondary organic aerosol (SOA) because they probably produce oxidation products that can condense onto the aerosol phase. We estimated the contribution of the sunscreen esters themselves and their oxidation products on the SOA formation for the Las Vegas area using a BVOC emission model. The contribution was estimated to reach 50% of the biogenic terpenoid Correspondence to: Sou Matsunaga (sou@tmu.ac.jp) emission in the landscapes dominated by desert willow and mesquite and 13% in the Las Vegas area. The contributions to biogenic SOA are likely to be higher due to the potentially high SOA yields of these compounds.
