As shown in Table 2, recoveries wer

As shown in Table 2, recoveries were essentially the same
in the 4 methods for all pesticides except acephate, omethoate,
and spinosyns A and D (spinosad). Similar results were obtained
with or without use of the IS, and both GC and LC results
are shown for those analytes that overlap to show the differences that can sometimes occur, possibly due to direct and/or
indirect matrix effects. Interestingly, the Na-adduct of aldicarb
yielded higher recovery when NaOAc was used for partitioning (AOAC 2007.01) than when ammonium buffers were used,
but this also occurred in the NH4Cl version. Variability of the
results and previous studies must be taken into account when
making conclusions, and curiosities such as the Na-adduct are
reported for possible follow-up investigations. As usual in multiclass, multiresidue analysis, trade-offs were observed among the
different versions, with the AOAC 2007.01 method yielding higher
recoveries for acephate and omethoate, but lower recovery for
spinosad.
Unfortunately, the results for all versions remained poor for
chlorothalonil, captan, and folpet due to degradation when those
pesticides are dissolved in MeCN solutions [5–8,15,18–23]. Endosulfan sulfate results were mysteriously unreliable from all 4
versions, but unlike the other analytes, this was unrelated to sample preparation and was resolved in a subsequent study [21]. Also
unexpectedly, the recoveries of pymetrozine were lower than usual

Seperti yang ditunjukkan dalam tabel 2, pemulihan yang pada dasarnya samadalam metode 4 untuk semua pestisida kecuali acephate, omethoate,dan spinosyns A dan D (spinosad). Hasil yang sama Diperolehdengan atau tanpa penggunaan hasil IS, dan kedua GC dan LCditampilkan untuk orang-orang analytes yang tumpang tindih untuk menunjukkan perbedaan-perbedaan yang dapat kadang-kadang terjadi, mungkin karena langsung dan/atauefek tidak langsung matriks. Menariknya, Na-adisi dari aldicarbmenghasilkan pemulihan yang lebih tinggi ketika NaOAc digunakan untuk partisi (AOAC 2007.01) daripada ketika amonium buffer digunakan,Tapi ini juga terjadi dalam versi NH4Cl. Variabilitashasil dan studi sebelumnya harus diperhitungkan ketikamembuat kesimpulan, dan keingintahuan seperti Na adisidilaporkan untuk kemungkinan penyelidikan tindak lanjut. Seperti biasa dalam analisis multiclass, multiresidue, trade-off yang diamati antaraVersi yang berbeda, dengan metode AOAC 2007.01 menghasilkan lebih tinggipemulihan untuk acephate dan omethoate, tapi lebih rendah pemulihan untukspinosad.Sayangnya, hasil untuk semua versi tetap miskin untukchlorothalonil, captan dan folpet karena degradasi ketika merekapestisida dilarutkan dalam solusi MeCN [5 – 8,15,18 – 23]. Endosulfan sulfat hasil yang misterius diandalkan dari semua 4Versi, tapi tidak seperti analytes yang lain, ini tidak terkait dengan preparasi sample dan diselesaikan dalam studi berikutnya [21]. Jugatiba-tiba, pemulihan pymetrozine lebih rendah dari biasanya
