Determination of organophosphorus pesticides in imported foods by FPD-GC and GC-MS.
Organophosphorus pesticides in 47 agricultural products imported at the Yokohama and Kobe Quarantine Station in 1990 were determined by FPD-GC and identified by GC-MS. Chlorpyrifosmethyl, malathion and fenitrothion were found in wheat (0.03-0.69 ppm), chlorpyrifosmethyl and fenitrothion in soy bean (0.02-1.03 ppm), chlorpyrifosmethyl in cherry (0.12-0.17 ppm), chlorpyrifosmethyl in pumpkin (0.07-0.15 ppm), chlorpyrifosmethyl and malathion in corn (0.15-1.38 ppm).
