3 Method summary
After the sample of pesticide residues via Easy solid phase extraction (SPE), acephate and other 12 kinds of pesticides (see Appendix A table in paragraph A.1
Ⅰ group) was measured by gas chromatography, fenitrothion and other 13 kinds of pesticides (see Appendix A in Table A.1 group Ⅱ) by gas chromatography - mass spectrometer
Fixed, bensulfuron-methyl and other six kinds of pesticides (see Appendix A in Table A.1 group Ⅲ) by liquid chromatography - mass spectrometry/mass spectrometer, matrix-matched standards
