Ozone concentration in Tokyo Metropolitan area is one of the most serious issues of the local air quality. Tropospheric ozone is formed by radical reaction including volatile organic compound (VOC) and nitrogen oxides (NO x ). Reduction of the emission of reactive VOC is a key to reducing ozone concentrations. VOC is emitted from anthropogenic sources and also from vegetation (biogenic VOC or BVOC). BVOC also forms ozone through NO x and radical reactions. Especially, in urban area, the BVOC is emitted into the atmosphere with high NO x concentration. Therefore, trees bordering streets and green spaces in urban area may contribute to tropospheric ozone. On the other hand, not all trees emit BVOC which will produce ozone locally. In this study, BVOC emissions have been investigated (terpenoids: isoprene, monoterpenes, sesquiterpenes) for 29 tree species. Eleven in the 29 species were tree species that did not emit BVOCs. Three in 12 cultivars for future planting (25 %) were found to emit no terpenoid BVOCs. Eight in 17 commonly planted trees (47%) were found to emit no terpenoid BVOC. Lower-emitting species have many advantages for urban planting. Therefore, further investigation is required to find the species which do not emit terpenoid BVOC. Emission of reactive BVOC should be added into guideline for the urban planting to prevent the creation of sources of ozone. It is desirable that species with no reactive BVOC emission are planted along urban streets and green areas in urban areas, such as Tokyo.

“…Spring monoterpene emissions were lowest despite the rain. Different E s values between seasons has been reported for Scots pine (Janson, 1993;Tarvainen et al, 2005;Hakola et al, 2006;Holzke et al, 2006), Pinus desiflora (Tani et al, 2002) and C. japonica (Matsunaga et al, 2011). E s values of Scots pine increased in spring and reached its peak in early summer.…”

“…It was reported to decrease thereafter (Hakola et al, 2006;Holzke et al, 2006) or become high again to resist low temperatures (Janson, 1993). For the other monoterpene emitters, E s was reported to be highest in summer in all cases (e.g., Kim, 2001;Tani et al, 2002) except for a report that E s for C. japonica was high in fall and winter and lowest in summer (Matsunaga et al, 2011). To explain these seasonal variations in E s , Steinbrecher et al (2009) proposed the use of a correction factor considering seasonal variation of monoterpene synthesis and emission from storage organs in an emission model.…”

“…The flow rate was adjusted by a mass flow controller (SEC-E40, HORIBA STEC, Japan). The air was flowed out of 20 holes (3 mm diameter) made on a Teflon tubing ring to mix the inside air well (Matsunaga et al, 2011). Leaf temperature and photosynthetic photon flux density (PPFD) were measured by thin thermocouples and semiconductor light sensors (S1133, Hamamatsu Photonics, Japan) and were recorded every minute using a data logger (CR1000 Campbell Scientific Inc.).…”

Monoterpenes are major compounds emitted by plants and contribute to the formation of photochemical oxidants and secondary organic aerosols in the troposphere. We measured monoterpene emissions from Chamaecyparis obtusa, a major coniferous tree species in Japan, in both the field and the laboratory. Short-term monoterpene emission from C. obtusa was typically dependent on temperature but barely dependent on light intensity. We calculated the basal emission rate E s assuming β = 0.09 in the G93 model. Three individual trees showed similar, but large seasonal variations in E s ; e.g., 0.21-5.42 µg g DW -1 h -1 for a tree showing the highest emission rate. The emission rate was much higher in winter and autumn. Although E s values averaged over 4 seasons indicated that C. obtusa is an intermediate emitter among coniferous trees, our results suggest that the large seasonal variation in E s should be considered in estimating annual monoterpene emission from this species. Furthermore, we found a significant effect of branch-to-branch touching by vibration on monoterpene emission from this species, suggesting that wind effect should be considered in the future for more precise emission estimation.

Formation and evolution of biogenic secondary organic aerosol over a forest site in Japan

[1] Chemical composition of atmospheric aerosol particles was characterized using an Aerodyne high-resolution time-of-flight aerosol mass spectrometer at a forest site in Japan during 20-30 August 2010. A major fraction of nonrefractory submicron aerosol particles consisted of organics (accounting for, on average, 46% of total mass), sulfate (41%), and ammonium (12%). Positive matrix factorization of high-resolution organic aerosol mass spectra identified two oxygenated organic aerosol (OOA) components: a highly oxidized, low-volatility OOA and a less oxidized, semivolatile OOA (SV-OOA), interpreted mainly as aged regional organic aerosol (OA) and as locally formed biogenic secondary OA (BSOA), respectively. The mass concentrations of SV-OOA increased prominently during the daytime, suggesting a strong photochemical production of BSOA on both nonevent and new particle formation event days. Increases of f 44 (fraction of m/z 44 in OA mass spectrum), the fraction of C x O y + fragment, and the O/C ratio after midday (around 13:00 local time) suggest that OA became increasingly oxygenated, which can be explained by the aging of freshly formed BSOA. Aqueous phase oxidation reactions under conditions of high relative humidity may have played a vital role in the aging of BSOA in this forest atmosphere. A substantial increase of the mass concentration of organics in the small size range (below 300 nm in vacuum aerodynamic diameter), without an increase in that of sulfate, suggests that the formation of BSOA made a dominant contribution to the presence of particles of cloud condensation nuclei size around the studied area.Citation: Han, Y., Y.
