Daily intake of glyphosate in 2010 and 2011 at Chiba prefecture was estimated using total diet samples prepared according to the market basket method. One hundred eighty six and 175 kinds of foods were purchased from supermarket at Chiba in December 2010 and December 2011, respectively. The purchased foods were divided into 14 food groups as total diet samples, and contents of glyphosate in those groups was analysed by high-performance liquid chromatography with fluorescence (HPLC-FL). Glyphosate was detected from second food group (Cereals and potatoes) and 13th food group (Seasonings and spices, other foods) among 14 food groups. Estimated daily intake of glyphosate in all food groups were 24.2μg/day in 2010, and 17.6μg/day in 2011. These estimated daily intake were accounted for 0.064% in 2010, and 0.047% in 2011 of the ADI assuming a body weight of 50 kg. The foods contribute to glyphosate detected from second food group were breads, fu, boiled noodle, macaroni, and that in 13th food group was soy sauce. Glyphosate detected by HPLC-FL method from above two food groups and those foods was identified by liquid chromatography with tandem mass spectrometry. Above these foods were all contained flour. Therefore, it seems to be high possibility that detected glyphosate is originated from flour.

畜水産物を主原料とする加工食品中の残留農薬について一斉分析法を検討した.均一化した試料に酢酸エチル-シクロヘキサン(1 : 1)および硫酸ナトリウムを加えて抽出,濃縮後,アセトニトリル/ヘキサン分配およびC18ミニカラムで脱脂し,グラファイトカーボン/PSAミニカラムで精製した.分析にはイオントラップ型GC/MSを使用し,スキャン法で測定した.スキャン法での測定が困難な農薬についてはMS/MS法でスキャン法と同時に測定した.試料4種(冷凍餃子,ウナギ蒲焼,コンビーフ,レトルトカレー)について292成分の添加回収試験 (0.1 μg/g添加) を行った結果,210 (レトルトカレー) ~262 (冷凍餃子) 成分が回収率 70~120% の範囲であった.本法は畜水産物を主原料とする加工食品中の残留農薬検査に有用な分析法であると考えられる.
