実験系廃液は、ひとたび取り扱いを誤ると、事故や環境汚染のリスクが著しく大きくなる。廃液処理とは、廃液の化学物質としてのリスクを除去することである。これには無害化処理の様な技術面だけでなく、構成員への教育の様な運用面の活動も含まれる。リスクの低減の最も大きな因子は、構成員及び廃液処理担当者が当事者意識を持つことである。 また、廃液管理活動を通じて、化学の負の側面を知る真に環境配慮が出来る人材を養成することも、大学等が果たすべき使命と考える。 大学等において、実験系廃液の無害化処理形態に自家処理と外注処理が有るが、廃液に係るリスクの除去と言う活動の本質において、両者に大差はない。 自家処理の場合は教育及び人材育成の効果が顕著でありそれが廃液を含む実験系廃棄物全体のリスクの低減につながる点が有利である。 その一方で、外注処理は労力と費用を削減すればするほど構成員および担当者の意識を保つことが難しいので、意識が低下しないように注意が必要である。廃液管理を適切に行う事で、廃棄物管理全体の管理も容易になる。 - Shigeru Taguchi, Miyabi Asaoka, Eiko Hirokami, Noriko Hata, Hideki Kuramitz, Takanori Kawakami, Ryuta MiyatakeANALYTICAL METHODS 7 16 6545 - 6551 2015年 [査読有り][通常論文]
A simple and rapid pre-concentration technique was proposed for the simultaneous determination of eight trace heavy metals in water by energy-dispersive X-ray fluorescence (EDXRF) spectrometry. Yttrium was added as a carrier ion to a sample solution containing Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. The metals were collected on a membrane filter as precipitates or co-precipitates with 1-(2-pyridylazo)-2-naphthol at pH 10. The metals on the filter were determined by EDXRF spectrometry. Yttrium improved the collection efficiency of Cr(III) drastically and also expanded the pH ranges for quantitative recoveries of the metals. Only fifteen minutes was required to prepare the membrane filter retaining the metals. Linear calibrations were obtained from mu g L-1 to mg L-1 levels of the metals in 50 mL sample solution. The limits of detection were as follows: Cd, 1 mu g L-1; Cr, 0.3 mu g L-1; Cu, 1 mu g L-1; Fe, 1 mu g L-1; Mn, 0.3 mu g L-1; Ni, 2 mu g L-1; Pb, 2 mu g L-1; and Zn, 2 mu g L-1. The sensitivities were sufficient for monitoring drinking water. The proposed method was applied to river water and underground water samples. The analytical results agreed with those obtained by GF-AAS for the detected metals. The recoveries of the spiked metals in the water samples were quantitative. This method was extended to the separation and determination of Cr(III) and Cr(VI). The proposed system of pre-concentration and EDXRF spectrometry has high potential for routine monitoring of trace heavy metals because of its simplicity and rapidity besides cost-effectiveness. - Sazawa, Kazuto, Tachi, Masaki, Wakimoto, Takatoshi, Kawakami, Takanori, Hata, Noriko, Taguchi, Shigeru, Kuramitz, HidekiINTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 8 5 1655 - 1670 2011年05月 [査読有り][通常論文]
The dissolved organic matter (DOM) is one of the important factors for controlling water quality. The behavior and constitutions of DOM is related to the risk of human health because it is able to directly or indirectly affect the behavior, speciation and toxicity of various environmental pollutants. However, it is not easy to know the contents of DOM components without using various complicated and time consuming analytical methods because DOM is a complex mixture and usually exists at low concentration. Here, we describe the fluorescence properties of DOM components in water samples collected from four rivers in Toyama, Japan by means of the three-dimensional excitation-emission matrix (3DEEM) fluorescence spectroscopy. In order to evaluate the alterations of DOM components in each of the river during the flow from upstream to downstream, the patterns of relative fluorescence intensity (RFI) at six peaks which are originated from fluorophores including humic-like and protein-like components were investigated. The changes in the patterns of RFI values at each of the peak and the concentration of dissolved organic carbon (DOC) for each river water sample were discussed in connection with the differences of land use managements and basic water quality parameters, such as pH, EC, turbidity, Fe(3+), T-N, NO(3)-N, T-P, PO(4)-P, chlorophyll a, DOC and N/P ratio. The DOC concentrations in the water samples collected from these rivers were relatively low (0.63-1.16 mg/L). Two main peaks which have a strong RFI value expressed a positive correlation with the DOC concentration (r = 0.557, 0.535). However, the correlations between the RFI values for other four peaks and the DOC concentration were below 0.287. The alterations of DOM components during the flow of a river from upstream to downstream were investigated from the changes in the patterns of RFI values for six fluorescent peaks. It was clarified that the great increase of RFI values in peak A and peak T from river water located in urban area showed high concentration of PO(4)-P and Fe(3+), and low N/P ratio due to the high biological activities. The values of fluorescence index (FIX) and biological index (BIX) were as high as 1.60 and 0.72, respectively. - 川上 貴教環境と安全 1 2 25 - 31 Academic Consociation of Environmental Safety and Waste Management, Japan 2010年 [査読有り][通常論文]
2005～2009年度の富山大学五福地区での不要試薬取引について、リレーショナルデータベース型化学薬品管理システムによるデータ収集結果を元に調査を行った。 5年間で635件の不要試薬公開があり、そのうち30.7%の195件の取引が成立した。それにより\1,044,814の費用節約効果が得られた。約４割の研究室は不要試薬取引所を利用しており、退官する教員の試薬が大量出品されたり、有機合成化学系の研究室が積極的に引き取る傾向がみられた。なお、85%の取引は部局内ではなく異部局間で行われた。引取りを待つ期間としては約2ヶ月が適当であり、それ以上は廃棄手続をするのが望ましい。使用している研究室の数と、取引成立率には一定の相関がみられた。特に洗浄や中和に使われる有機溶媒や酸アルカリはよく引き取られた。また、未開封であることは有利な条件であった。 - 倉光 英樹, 佐澤 和人, 七山 泰昭, 工藤 千春, 川上 貴教, 波多 宣子, 田口 茂水環境学会誌 = Journal of Japan Society on Water Environment 32 6 309 - 314 Japan Society on Water Environment 2009年06月 [査読有り][通常論文]
Dissolved organic matter (DOM) significantly relates to the speciation of heavy-metal ions in aquatic environments. To evaluate the toxicity changes of heavy-metal ions induced by the existence of DOM or dissolved humic substances (DHS), a microscaled algal growth inhibition (μAGI) test was conducted using a commercially available 96-well micro-plate. The μAGI test was compared with a regular AGI test using an Erlenmeyer flask. A regular AGI test is not very beneficial for accessing the toxicity of chemicals in an aqueous solution containing DOM or DHS because it absorbs visible light, which is required for algal growth. However, in this study, we clarified that the amount of algal growth in the μAGI test is hardly affected even at a high DHS concentration. The changes in the toxicity of copper to Chlamydomonas reinhardtii were evaluated under two conditions of the μAGI test, that is, with and without DOM/DHS. DOM and DHS samples were extracted from freshwater samples from Sakata in Niigata prefecture, Japan. The toxicity mitigation coefficients (TMCs) at 10 mgC · <I>l</I>-1 DOM and DHS were estimated to be 1.4-2.7 and 4.8, respectively. Evidence found in this study shows that DHS strongly reduces the toxicity of copper (II) to algae, as compared with nonhumic components in DOM. - Keita Murai, Mayumi Okano, Hideki Kuramitz, Noriko Hata, Takanori Kawakami, Shigeru TaguchiANALYTICAL SCIENCES 24 11 1455 - 1459 2008年11月 [査読有り][通常論文]
A simple and sensitive spectrophotometry for formaldehyde in water by membrane solubilization technique was proposed. Formaldehyde was converted into a blue cationic dye with 3-methyl-2-benzothiazolinone hydrazone, and the dye was retained on a membrane filter as an ion-associate with tetraphenylborate anion. The filter retaining the blue dye was dissolved in 2-methoxyethanol containing sulfuric acid, and the absorbance of the solution was measured at 670 nm against the reagent blank. The formaldehyde from 0.007 to 0.2 mg L-1 was determined with an RSD of less than 5%, and the detection limit was 0.002 mg L-1. The proposed method was very simple and rapid. Twenty minutes was sufficient for the entire analytical procedure. When the method was applied to rainwater, the analytical results were in good agreement with those obtained by GC/MS. - Hiroyuki Higuchi, Naoto Hayashi, Takuya Matsukihira, Takanori Kawakami, Toru Takizawa, Junji Saito, Keiko Miyabayashi, Mikio MiyakeHETEROCYCLES 76 1 353 - 380 2008年09月 [査読有り][通常論文]
The octaethylporphyrin (OEP)-dihexylbithiophene (DHBTh) derivatives combined with pyridine (Pyr) and pyrimidine (Pym) as proton-acceptable rings (PAR) were synthesized, describable as OEP-DHBTh-PAR, in which all the OEP, DHBTh, and PAR components are connected with diacetylene linkage. Their (1)H NMR and electronic spectral properties and electrochemical behaviors were studied under the neutral and acidic conditions. Reversible proton-mediated and heat-driven spectral changes of OEP- DHBTh-PAR were performed, reflecting both properties of PAR and DHBTh. - Investigation of formaldehyde pollution of tap water and rain water using a novel visual colorimetryK.

The pollution of tap water and rain water with formaldehyde in Toyama Pref., Japan was investigated by means of a simple, rapid and cost-effective visual colorimetry developed by us. The levels of formaldehyde in three tap waters from different sources of dams on mountainside and a well-water pumped in urban area in Toyama Pref. were lower than 0.01 mgL(-1) that was the detection limit of the colorimetry. On the other hand, rain waters were seriously polluted with formaldehyde. Rain waters were sampled from three different sites (urban area, top of hill and industrial area) in Toyama Pref. from autumn to winter in 2006. The levels of formaldehyde in the rain waters ranged from 0.07 to 0.30 mgL(-1). The analytical results by the visual colorimetry were in good agreement with those obtained by GC-MS method. It was confirmed that the colorimetry is excellent for practical use for the determination of formaldehyde. It must be concerned about the pollution of rainwater with formaldehyde, when rain water is applied for tap water and miscellaneous purpose. - Shigeyasu Kuroda, Mitsunori Oda, Hiroaki Takamatsu, Hirofumi Hatakeyama, Chisa Noda, Yanmei Zhang, Ryuta Miyatake, Nguyen Chung Thanh, Atsusi Yanagida, Mayumi Kyougoku, Takanori KawakamiSCIENCE AND TECHNOLOGY OF ADVANCED MATERIALS 8 4 306 - 317 2007年05月 [査読有り][通常論文]

Significant acceleration of Beckmann and pinacol rearrangements can be achieved by using supercritical water (scH(2)O), especially just near the critical point even in the absence of any acid catalysts. A high-pressure, high-temperature flow reactor system with FTIR operable at 500degreesC and 50 MPa was successfully developed, wherein the noncatalytic Beckmann and pinacol rearrangements using scH(2)O Were carried out and monitored. It has been demonstrated that scH(2)O itself acts very effectively in the place of conventional acid catalysts for both the rearrangements. The rate of the pinacol rearrangement using scH(2)O is 28,200-fold rate of that in 0.871 M HCl solution at 46.7 MPa under distillation conditions. The high rate of reaction may be attributed to a great increase in the local proton concentration around the organic reactants. - Mitsuhiro Kanakubo, Chee C.

1H NMR longitudinal relaxation times (T1 obs) of water in supercritical carbon dioxide were precisely measured as a function of water concentration (c) at 313.3 K and at 10 and 20 MPa. I/T1,obs linearly decreased with increasing c up to ∼ 12 mol m-3, and then was less sensitive to c. Because the spinrotation interaction is the predominant mechanism in T1 obs, the concentration dependence reflects a change in the hydrogen bonding structure between water molecules in the solutions. - T Kawakami, N Saito, Y Ikushima, CC Liew, K Aiba, T OhkawaCHEMISTRY LETTERS 4 402 - 403 2000年04月 [査読有り][通常論文]
We have developed a new series of branch-structured anionic surfactants dissolved significantly well in sc-CO2. We found that, the variation of counter ion species has a significant effect on the solubility of the surfactants in sc-CO2. Among these, the solubility of surfactant with ammonium ion exceeded 16 wt% at 40 degrees C and 15 MPa while that of surfactant with K+ was neglectable. This effect can be used for complete recovery of the surfactant. - M Kanakubo, T Aizawa, T Kawakami, O Sato, Y Ikushima, K Hatakeda, N SaitoJOURNAL OF PHYSICAL CHEMISTRY B 104 12 2749 - 2758 2000年03月 [査読有り][通常論文]
A newly designed high-pressure NMR flow cell has been developed for studies of supercritical fluids. By using the high-pressure cell, H-1 chemical shifts of nonpolar (n-hexane and benzene) and polar (dichloromethane, chloroform, acetonitrile, water, methanol, and ethanol) solute molecules in gaseous and supercritical carbon dioxide were measured in the wide pressure range between 2 and 30 MPa at 313.3 K. The chemical shifts of hydroxyl protons of water, methanol, and ethanol in carbon dioxide at 20.0 MPa were shifted to higher frequency due to intermolecular hydrogen bonding with increasing concentration. A comparison of the concentration dependence with relevant data in carbon tetrachloride indicated a specific interaction between alcohol and carbon dioxide molecules. The corrected H-1 chemical shifts of nonpolar and polar solute molecules at infinite dilution, where the bulk magnetic susceptibility contribution was subtracted, were shifted to higher frequency with increasing density of carbon dioxide. The observed density dependence, represented by a polynomial equation of the third power of density, was interpreted in terms of three distinct density regions, i.e., gaslike, intermediate, and liquidlike. In the gaslike and liquidlike states the solvation structure rapidly varies as the bulk density increases, whereas in the intermediate state the solvation structure remains almost unchanged despite the drastic change in the bulk density. It was demonstrated that the H-1 chemical shift is quite a sensitive probe to a variation of surroundings. The solvent-induced H-1 chemical shifts were analyzed on the basis of two different models. - Mitsuhiro Kanakubo, Takafumi Aizawa, Takanori Kawakami, Osamu Sato, Yutaka Ikushima, Kiyotaka Hatakeda, Norio SaitoJournal of Physical Chemistry B 104 2749 - 2758 2000年03月 [査読有り][通常論文]

The asymmetric porphyrin derivative having only one reaction site, A(1)Py(3)P [5-(4-aminophenyl)-10,15,20-tris(4-pyridyl)porphine], was synthesized [epsilon=2.1 x 10(5) M-1 cm(-1) (pH 1.0, at 441 nm)]. UV, IR and mass spectral measurements, elemental analysis and thin layer chromatography were carried out for identification of A(1)Py(3)P. It was demonstrated that the porphyrin reacted with nitrite in a mole ratio of 1 : 1, giving a useful spectral change. The spectrophotometric determination of nitrite using A(1)Py(3)P was excellent with respect to calibration linearity: 0-8.0 x 10(-7) M, detection limit (3 sigma): 7.0 x 10(-9) M, relative standard deviation: 1.0%, for 10 determinations at 4.0 x 10(-7) M.

A water-soluble porphyrin having four aminophenyl groups 5,10,15,20-tetrakis(4-aminophenyl)porphine (TAPP) diazotizes with nitrite ion and produces a large spectral change (epsilon: molar absorptivity, Delta epsilon=epsilon(sample)-epsilon(blank)=3.0 x 10(5) M-1 cm(-1), 434 nm), The coexistence of L-ascorbic acid (AsA) strongly interferes with this reaction, Therefore, a highly sensitive spectrophotometric determination of AsA was developed using this effect, For the determination of trace amounts of AsA, the calibration curve was linear in the concentration range of 8.0 x 10(-8)M-5.0 x 10(-7) M (14-88 ppb), The detection limit (3 sigma) was 1.0 x 10(-8) M (1.76 ppb), and the relative standard deviation was 1.86% (2.0 x 10(-7) M (35 ppb) AsA, 6 determinations). This method is more than 20 times highly-sensitive than the indophenol method as standard spectrophotometry for AsA. This method has been applied to the determination of AsA in soft drinks and drugs. - T Kawakami, S IgarashiANALYTICA CHIMICA ACTA 333 1-2 175 - 180 1996年10月 [査読有り][通常論文]
A water-soluble porphyrin having the aminophenyl group, 5,10,15,20-tetrakis(4-aminophenyl)porphine, reacts with nitrite ion, and produces a large spectral change (Delta epsilon = 3.0 x 10(5) l mol(-1) cm(-1), 434 nm). There are few interfering substances and it is easy to establish the reaction conditions because the spectral change mechanism is based only on diazotization. A highly sensitive spectrophotometric determination of nitrite was developed on this basis. The calibration graph was linear in the range 0 to 4.0 x 10(-7) mol l(-1) (0-18 ng ml(-1)). The detection limit {S/N = 3} was 4.0 x 10(-9) mol l(-1) (0.18 ng ml(-1)), and the relative standard deviation was 1.0% (at 2.0 x 10(-7) mol l(-1) nitrite, 10 determinations). This method has been applied to the determination of nitrite in rain, tap and spring water without any pretreatment. - 川上 貴教, 五十嵐 淑郎分析化学 45 1 91 - 93 公益社団法人日本分析化学会 1996年01月 [査読有り][通常論文]

A highly sensitive kinetic spectrophotometric determination for alkaline phosphatase (ALP) using 5,10,15,20-tetrakis (4-phosphonooxyphenyl)porphine (approximately Delta epsilon approximate to 3.0 x 10(5) I mol(-1) cm(-1)) was studied. With a measuring time of 30 min, the determination range was 2.0 x 10(-12)-8.0 X 10(-9) mol l(-1) and the detection limit (3s) was 1.0 x 10(-12) mol l(-1). The detection limit became lower on increasing the measuring time, For example, the detection limit was up to 10(-15) mol l(-1) for 12 h. This method was applied to the assay of ALP in human serum. Using 0.50 ml of sample without any pre-treatment, a good correlation was obtained with the p-nitrophenyl phosphate method, and the relative standard deviation was 4.7%. The method was also applied to the enzyme immunoassay of alpha-fetoprotein in human serum and provided a good correlation with the 4-methylumbelliferone derivative (r = 0.999) with approximately half the relative standard deviations (1.3-2.7%) obtained with a commercial kit. The proposed method requires very small sample volumes, is highly sensitive, highly accurate, and shows good stability of the reagent; it will be applied to various assays using ALP as label. - Shukuro Igarashi, Hiroyasu Furukawa, Takanori KawakamiAnalytical Proceedings including Analytical Communications 32 3 107 - 109 1995年 [査読有り][通常論文]

A new water-soluble porphyrin having the phosphate group, 5,10,15,20-tetrakis(4-phosphonooxyphenyl)porphine, was used as an ultra highly-sensitive chromogenic reagent of alkaline phosphatase enzyme activity. In the spectrophotometric determination of trace amounts of alkaline phosphatase with this reagent, the calibration curve was linear in the concentration range of 3.2 x 10(-5) to 6.4 x 10(-4) g/l and detection limit {S/N=3} of alkaline phosphatase was 8.0 X 10(-8) g/l (10(-12)M) for 30 min and the relative standard deviation was 3.5% (2.0 X 10(-5) g/l ALP, 10 determinations). This reagent was also stable for seven days in aqueous solution (37 degrees C, pH=9.4). - 五十嵐 淑郎, 神澤 義仁, 川上 貴教, 四ッ柳 隆夫, 金 尚元, 小塚 隆弘日本化学会誌 1993 2 184 - 188 公益社団法人 日本化学会 1993年 [査読無し][通常論文]
動脈硬化症病変部に特異性を有する新規NMRイメージング造影剤の開発を目的として,8種類のマンガン(III)-テトラキス(スルボアリール)ポルフィリン誘導体を合成した。スルホビフェニリル基を有するマンガン(III)-α,β,γ,δ-テトラキス(4-スルホビフェニリル)ポルフィリン(Mn-TSBP)は,水に対する溶解性(溶解度:5×10-3mol dm-3),錯体のpH安定性(pH1.5～13.5の範囲で安定),およびデオキシコール酸担体への吸着特性などの点で優れていた。動脈硬化症ウサギを作成し,合成した水溶性ポルフィリン錯体を投与した結果,Mn-TSBPは正常部組織よりも病変部組織に2倍以上選択的に吸着した。 - 五十嵐 淑郎, 神澤 義仁, 川上 貴教, 四ツ柳 隆夫, 金 尚元, 小塚 隆弘日本化学会誌 : 化学と工業化学 = Journal of the Chemical Society of Japan : chemistry and industrial chemistry 1993 2 184 - 188 日本化学会 1993年 [査読有り][通常論文]

局所排気装置（以下、局排）には性能維持のために定期的なメンテナンスが必要である。それにも関わらず充分な維持管理体制が整っている大学は多くない。局排の適切なメンテナンスを行うためには、大学側に局排について一定の知識が必要となる。そこで、先行して局排に取り組んできた静岡大学、茨城大学、筑波大学を中心とした有志により、大学向けの局排維持管理の解説書を作成した。また、そのメンバーを中心に局所排気装置の維持管理研究会が発足した。大学間での連携協力体制も構築でき、各大学における局排維持管理の取組みが盛んになることを期待する。 - 化学物質関連法規制の有無と自主管理のススメ川上 貴教 環境と安全 4 (1) 74 -74 2013年03月 [査読無し][通常論文]

大学等の研究機関の多くは、機関内の適切な試薬の管理を目指して、クライアントサーバ型の化学物質管理システムを導入し、試薬類の一元管理を行っている。しかし、これまで各大学等におけるシステムの導入・運用状況、メンテナンス・管理体制、および運用上の問題点については、不明な部分が多かった。<br> 本報告では、国立大学法人を主とする各大学等における化学物質管理システムの運用管理状況についてアンケートによる実態調査を行った。その結果、各大学等のシステムの運用における人員構成・配置、管理体制等が明らかとなった。特に、試薬マスタの管理に関しては、マスタ総登録件数、更新頻度、メンテナンス体制などの管理ポリシーが大学等によって大きく異なっていることが明らかとなった。 - 川上 貴教 ぶんせき (446) 64 -72 2012年02月05日 [査読有り][通常論文]
