    Abstract

    The hygroscopicity of atmospheric aerosols affect the global climate and human health. However, the hygroscopic behavior of mixtures of inorganic salts and organics in atmospheric aerosols have not been well characterized for ambient complex organic mixtures. Here, the hygroscopic growth of humic‐like substances (HULIS), which represent the complexity of organic aerosol compounds, from urban aerosols and their mixtures with ammonium sulfate were investigated with measurements from a hygroscopicity tandem differential mobility analyzer and model analyses. The Zdanovskii–Stokes–Robinson (ZSR) relationship, which assumes that the water uptake of each component is additive, was examined for the mixtures. The dependence of the hygroscopicity parameters (κ) of the mixtures on the volume fraction of HULIS is generally represented by the ZSR relationship with the deviations of κ on average of 16% (4%–27% in different mixing ratios), and 0.03 (0.02–0.04) on absolute basis. An assumption of asphericity for the dry particles reduced the deviations (14%). Approximations for the surface tension depression by surfactants and surface‐bulk partitioning were predicted to account for the deviations to a small extent. Furthermore, a thermodynamic model for simplified compound systems showed that the non‐ideality of the solutions potentially explained the deviations from the ZSR relationship. The results of this study support the use of the ZSR relationship for organic‒inorganic mixtures as a practical approximation in atmospheric models, provide a guide for the uncertainty associated with this approximation, and suggest directions for future studies.

    Abstract

    Atmospheric organic aerosol (OA) are considered as a significant contributor to the light absorption of OA, but its relationship with abundance, composition and sources are not understood well. In this study, the abundance, chemical structural characteristics, and light absorption property of HULIS and other low-to-high polar organics in PM<sub>0.95</sub> collected in Tomakomai Experimental Forest (TOEF) were investigated with consideration of their possible sources. HULIS were the most abundant (51%), and correlation analysis revealed that biogenic secondary organic aerosols significantly contribute to HULIS. The mass spectra obtained using a high-resolution aerosol mass spectrometer (HR-AMS) showed that HULIS and highly polar water-soluble organic matter (HP-WSOM) were substantially oxygenated organic aerosol fractions, whereas water-insoluble organic matter (WISOM) had a low O/C ratio and more hydrocarbon-like structures. The WISOM fraction was the predominant light-absorbing organics. HULIS and WISOM showed a noticeable seasonal change in mass absorption efficiency (MAE<sub>365</sub>), which was highest in winter. Further, HULIS were shown to be less absorbing than those reported for urban sites. The findings in this study provide insights into the contribution of biogenic secondary OA on aerosol property and radiative forcing under varying contributions from other types of OA.

    Abstract. Filter-based offline analysis of atmospheric aerosol hygroscopicity coupled to composition analysis provides information complementary to that obtained from online analysis. However, its application itself and comparison to online analysis have remained limited to date. In this study, daily submicrometer aerosol particles (PM0.95, 50 % cutoff diameter: 0.95 μm) were collected onto quartz fiber filters in Okinawa Island, a receptor of East Asian outflow, in the autumn of 2015. The chemical composition of water-soluble matter (WSM) in PM0.95 and PM0.95 itself, and their respective hygroscopicities were characterized through the offline use of an aerosol mass spectrometer and a hygroscopicity tandem differential mobility analyzer. Thereafter, results were compared with those obtained from online analyses. Sulfate dominated the WSM mass (60 %), followed by water-soluble organic matter (WSOM, 20 %) and ammonium (13 %). WSOM accounted for most (93 %) of the mass of extracted organic matter (EOM) and the atomic O to C ratios (O : C) of WSOM and EOM were high (mean ± standard deviation were, respectively, 0.84 ± 0.08 and 0.79 ± 0.08), both of which indicate highly aged characteristics of the observed aerosol. The hygroscopic growth curves showed clear hysteresis for most samples. At 85 % RH, the calculated hygroscopicity parameter κ of the WSM (κWSM), WSOM, EOM, and PM0.95 (κPM0.95) were, respectively, 0.50 ± 0.03, 0.22 ± 0.12, 0.20 ± 0.11, and 0.47 ± 0.03. An analysis using the thermodynamic E-AIM model shows, on average, that inorganic salts and WSOM respectively contributed 88 % and 12 % of the κWSM (or κPM0.95). High similarities were found between offline and online analysis for chemical compositions that are related to particle hygroscopicity (the mass fractions and O : C of organics, and the degree of neutralization), and also for aerosol hygroscopicity. As possible factors governing the variation of κWSM, the influences of WSOM abundance and the neutralization of inorganic salts were assessed. At high RH (70–90 %), the hygroscopicity of WSM and PM0.95 was affected considerably by the presence of organic components; at low RH (20–50 %), the degree of neutralization could be important. This study not only characterized aerosol hygroscopicity at the receptor site of East Asian outflow, but also shows that the offline hygroscopicity analysis is an appropriate method, at least for aerosols of the studied type. The results encourage further applications to other environments and to more in-depth hygroscopicity analysis, in particular for organic fractions.

    陸域植生から大気に放出される揮発性有機化合物の一部は、光化学反応により生物起源有機エアロゾル（BSOA）となり、雲凝結核としての働きなどにより放射収支に関与し、気候ひいては陸域植生に影響を及ぼすというフィードバック機構を形作ると指摘されている。しかし、エアロゾルの放射影響に関わる有機エアロゾルの吸湿性の推定値には大きな幅があり、BSOAの吸湿性や、その雲粒生成への寄与には大きな不確かさがある。そこで本研究では、北方森林圏を対象としてBSOAの吸湿性とその全エアロゾルの吸湿性に対する寄与を定量する。そして、北方林におけるBSOAの放射への寄与を評価し、上記のフィードバック機構について考察する。
    当該年度には、日本側の研究者がヒューティアラ森林フィールドステーションを訪問し、有機・無機エアロゾル成分の定量や有機エアロゾルの吸湿性パラーメータの解析を行うための大気エアロゾル試料を採取することを計画していたが、新型コロナウイルスの感染拡大のため、年度内の訪問を見送ることとした。そして、これに代わり、ヒューティアラ森林フィールドステーションにおいて名古屋大学のハイボリュームエアサンプラをヘルシンキ大学の関係者が運用し採取する試料を用いて、本研究のエアロゾル化学組成・吸湿性の解析を行う方針に切り替えることとした。この準備として、ハイボリュームエアサンプラによる大気エアロゾルの採取を実施するための手順書の作成を進めた。また、この大気エアロゾル試料の採取のため、PM0.95（粒径が0.95マイクロメータ以下の粒子）を捕集するためのフィルタと、粒径が0.95マイクロメータよりも大きな粒子を除去するインパクタ用基材の前処理（加熱）を行い、また、それらを輸送・保存用の容器に入れる作業を行った。そのほか、有機エアロゾルの吸湿性パラーメータや他の情報を用いた放射影響の解析のため、全球エアロゾルモデルの改良について検討を進めた。大気エアロゾルの雲凝結核活性を評価する上では、エアロゾルに含まれる界面活性物質による表面張力低下が及ぼす影響が考慮の対象となり、これに関わる検討結果（都市エアロゾル試料を用いた結果）の会議における発表も行った。
    新型コロナウイルスの感染拡大により、大気エアロゾルの採取のためのヒューティアラ森林フィールドステーションの今年度の訪問を見送ることとなった。これに伴い、採取する試料を用いる分析を次年度以降に行う方針に変更した。
    新型コロナウイルスの感染拡大に伴いヒューティアラ森林フィールドステーションにおける大気エアロゾル採取のための訪問が実現しておらず、当面は名古屋大学のハイボリュームエアサンプラをヘルシンキ大学の関係者が運用し採取する試料を用いて、本研究を進める計画に変更した。

    By utilizing the measurement data of the hygroscopic growth of atmospheric aerosols in Nagoya in September 2009, the respiratory deposition of atmospheric aerosol particles that a person inhaled was analyzed. The characteristics of the deposition of aerosol particles in the respiratory tract during the period was obtained based on the distributions of aerosol particles as a function of the dry diameter and hygroscopicity. Further, the importance of the consideration of the external mixing state of aerosols during the period was assessed. The influence of the consideration of time evolution on the calculation of the deposition, and the representation of the results from the analysis were studied.

    We aimed to elucidate the origin and formation processes of atmospheric water-soluble organic nitrogen (WSON) aerosols in forest environment. We found that aerosol liquid water content, primarily driven by anthropogenic sulfate, promotes aqueous reactions of reactive nitrogen and biogenic organic carbon to be the dominant formation processes of WSON, particularly during nighttime.

    Atmospheric aerosols particles play an important role in adverse health effects. Respiratory deposition of ambient particulate matter and their interactions with lung antioxidants can lead to the formation of reactive oxygen species (ROS) that may contribute to oxidative stress. In this project we measured ROS contained in ambient particles collected in an urban air in Nagoya, Japan, using a cascade impactor. Applying electron paramagnetic resonance spectrometry, we detected substantial amounts of environmentally persistent free radicals in collected particles. For detection of ROS we applied a spin counting method. Other atmospheric pollutants were also measured and we found that stable radicals and ozone anti-correlated. In summer 2017, another particle sampling has been conducted in a forest site in Wakayama. While concentrations of free radicals were under detection limit, we observed that particles generate ROS in water.
