Fernandez M, Pico Y, Girotti S, Manes J: Analysis of organophosphorus pesticides in honeybee by liquid chromatography-atmospheric pressure chemical ionization-mass spectrometry. J Agric Food Chem. 2001 Aug;49(8):3540-7.
The extract was purified with coagulating solution and reextracted with Cl (2) CH (2). Pesticides studied could be detected by both ionization modes except for parathion, parathion-methyl, and bromophos, which did not give signals in PI mode, and triazophos, which was not detected in NI mode. |
