※本報告書は、試験法開発における検討結果をまとめたものであり、試験法の実施に際して参考として下さい。 なお、報告書の内容と通知または告示試験法との間に齪酷がある場合には、通知または告示試験法が優先す ることをご留意ください。 平 成 20 年度 残留農薬等個別試験法開発 カルベンダジム他 3 物質 一式 カルベンダジム、チオファネート、チオファネートメチル及びベノミル試験法の検討結果 [緒言] 1.目的及び試験法の検討方針 カルベンダジム(MBC)、チオファネート、チオファネートメチル及びベノミルはカーバメート系農 薬に大別される殺菌剤である。既存のカルベンダジム、チオファネート、チオファネートメチル及びベ ノミルの通知試験法は、チオファネートメチル及びベノミルをMBCに、チオファネートをエチル2-ベン ズイミダゾールカルバマート(EBC)に変換して、同時に分析試験を行う方法であるが、転溶操作中の 分解や閉環反応における回収率が低いなどの問題点がある。試験法の作成に際して、通知試験法及び飼 料分析基準[カルベンダジム(カルベンダジム,チオファネートメチル及びベノミル)]を参考に各種精 製操作及び閉環反応を検討した。測定機器にLC-MS/MSを用いて感度及び選択性をあげることにより、 試料溶液の分取率を下げ、分析閉環反応前の転溶を省略することで、良好な結果が得られた。また、通 知試験法では、検量線は閉環反応を行ったカルベンダジム及びチオファネートを用いて作成しているが、 本方法では、未反応のカルベンダジム及びEBCを用いて検討を行った。 2.構造式等 カルベンダジム(MBC) 構造式: H N N NHCO2CH3 化学式:C9H9N3O2 分子量:191.19 溶解性:水

液体クロマトグラフ・タンデム型質量分析計(LC-MS/MS) 1)MS/MSスペクトル(図1-1、図2-1) カルベンダジムはESI(+)でプリカーサーイオンm/z=192.1からプロダクトイオンm/z=160.0(定量 用)及びm/z=132.1(確認用)が確認された。 EBCはESI(+)でプリカーサーイオンm/z=206.2からプロダクトイオンm/z=160.0(定量用)及びm /z=134.0(確認用)が確認された。 2)測定条件 機種:1200 Series[Agilent Technologies] 検出器:API-3200QTRAP[AB SCIEX] カラム:Mightysil RP-18 GP 内径2.0 mm、長さ150 mm、粒子径5 μm[関東化学株式会社] カラム温度:40℃ 移動相: 2 mmol/L酢酸アンモニウム溶液及びメタノールの混液(3:2)で5分間保持し、(3:2)か ら(1:19)までの濃度勾配を5分間で行った後、(1:19)で5分間保持する。 移動相流量:0.2 mL/分 イオン化モード:ESI(+) イオン化温度:400℃ イオン化電圧:5,000 V 主なイオン(m/z): カルベンダジム;プリカーサーイオン192、プロダクトイオン160(定量) プリカーサーイオン192、プロダクトイオン132(確認) EBC:プリカーサーイオン206、プロダクトイオン160(定量) プリカーサーイオン206、プロダクトイオン134(確認) 注入量:2 μL 保持時間の目安:カルベンダジム 7分、EBC 11分 定量限界相当の検出量:0.0005 ng(0.00025 mg/L×2 μL)のピークのS/N比は、カルベンダジムの 確認イオン(m/z = 192→132)が定量イオン(m/z = 192→160)の5分の1程度、EBCの確認イオン(m /z = 206→134)が定量イオン(m/z = 206→160)の2倍程度で、ともに10以上であった。 なお、EBCは確認イオンの方が定量イオンと比べ感度が良いが、選択性のより良い、m/z = 206→ 160を定量用とした。 3)検量線の直線性 以下の6段階濃度に調製した標準溶液を注入し、作成した検量線を図1-2、2-2に示した。この濃度範 囲で良好な直線性を確認した。 カルベンダジム及びEBC:0.000125 mg/L(0.00025 ng)から0.02 mg/L(0.04 ng) 4)標準溶液の検出感度(図1-3、2-3) 9 定量限界相当の検出量:0.0005 ng(0.00025 mg/L×2 μL)のピークのS/N比は、カルベンダジム及 びEBCでともに10以上であった。 2.試験溶液調製法の検討結果 1)チオファネート及びチオファネートメチルの直接定量についての検討 チオファネート及びチオファネートメチルについてそれぞれの化合物を閉環反応せずに直接定量する ことが可能か検証するため、下記①から⑤の精製を検討した。その結果、精製中の分解が疑われる場合 やジクロロメタンを使用する必要があるなどの問題があったため、閉環反応し同時に分析する方法をと ることとした。 ①酢酸エチル及びn-ヘキサン(1:1)への転溶 既存の通知試験法を参考として検討を行った。 チオファネート及びチオファネートメチル各1 μgに10%塩化ナトリウム溶液100 mL及び1 mol/L水酸 化ナトリウム溶液5 mLを加え、酢酸エチル及びn-ヘキサン(1:1)の混液100 mL及び50 mLで2回振と う抽出を行い、結果をTable 1に示した。Table 1より、チオファネートはほぼEBCに変換していた。チオ ファネートメチルはそのものの回収率は0%で、一部カルベンダジムへの変換がみられたが、チオファネ ートメチルとカルベンダジムの合計の収支から6割以上が分解していると予想された。 Table 1 酢酸エチル及びn-ヘキサン(1:1)の混液への転溶(%)

mL及び50 mLで3回振とう抽出を行い、結果をTable 2に示した。Table 2より、チオファネート 及びチオファネートメチルは、200 mLで完全にジクロロメタンに移行していた。しかしジクロロメタン の使用を避けるため、本転溶法は採用しなかった。 Table 2 ジクロロメタンへの転溶(%) ジクロロメタン 100 mL(1回目) 100 mL(2回目) 50 mL(3回目) 合計

14より、本試験法の回収率はカルベンダジムが平均90%、チオ ファネートメチルが平均79%と、既存の試験法と比べて回収率が向上した。さらにチオファネートの 回収率は平均81%、EBCは83%であった。 Table 14 閉環反応操作の回収率(%) 試行数 合計 1 2 3 カルベンダジム 90 91 90 90 チオファネートメチル 78 80 78 79 チオファネート 87 81 74 81

を反応したときにチオファネート及びチオファネートメチルの回収率が標準品のみを閉環反応させた 場合と同程度であった。またTable 17より、茶葉及び浸出液ではそれぞれの試料溶液を10倍希釈後、2 mLを反応に用いたときにチオファネート及びチオファネートメチルの回収率が標準品のみを閉環反 応させた場合と同程度であった。よって、閉環反応に用いる試料溶液は1 mLとし、茶葉及び浸出液で は10倍希釈後の試料溶液を2 mLとした。 Table 16 試料溶液の分取量による反応率(%) 分取量(mL) 反応率(%) チオファネート チオファネートメチル 4 48 32 2 40 39 1 80 79 試料:玄米 Table 17 試料溶液の分取量による反応率(%) 試料 茶葉 浸出液 分取量 反応率(%) チオファネート チオファネートメチル 1 mL 36 105 10倍希釈後2

g採取して約50℃の湯せんで再度溶解したところに、カルベンダジム、チオ ファネート、チオファネートメチル及びベノミルを添加した。添加後、2時間冷蔵庫で冷やし固めたも 16 のについて、メタノールで抽出を行った。回収試験の結果をTable 18に示した。脂肪をメタノールでホ モジナイズ抽出した場合、十分に分散しており、本検討の回収率も問題なかったことから、脂肪につ いても抽出溶媒は農産物同様、メタノールで問題ないと判断した。 試料 添加濃度 (ppm) 牛の脂肪 0.07 Table 18 脂肪からの抽出確認試験の回収率 回収率(%) チオファネート カルベンダジム チオファネート メチル 102 89 87 ベノミル EBC 106 96 3.添加回収試験 農産物は玄米、大豆、ばれいしょ、キャベツ、ほうれんそう、オレンジ、りんご及び茶の8品目になす

この試験法を玄米、大豆、ばれいしょ、ほうれんそう、オレンジ、キャベツ、なす、りんご、コーヒ ー豆及び茶の農産物10品目と、牛の筋肉、牛の肝臓、乳、鶏の筋肉、鶏の卵、さけ、うなぎ、しじみ及 びはちみつの畜水産物10品目の試料に適用した場合、真度はカルベンダジム79~104%、チオファネート 76~105%、チオファネートメチル74~107%、ベノミル76~103%、EBC78~105%であり、定量限界は 茶でそれぞれ0.05 mg/kg、そのほかの食品でそれぞれ0.01 mg/kgが可能であることが確認された。 [参考文献] 1.食品に残留する農薬、飼料添加物又は動物用医薬品の成分である物質の試験法 カルベンダジム、
