A liquid chromatography–mass spectr

A liquid chromatography–mass spectrometry (LC–MS) method was established for the purpose of simultaneous determination of carbamate and
organophosphorus (OPPs) pesticides in fruits and vegetables. Samples were extracted with acetonitrile; and then prepared by dispersive solid-phase
extraction (dispersive-SPE) with primary secondary amine (PSA) as the sorbent. Four common representative samples (tomato, apple, carrot, and
cabbage) were selected from the supermarket to investigate the effect of different matrices on pesticides recoveries and assay precision after spiking
samples with 0.05 mg/kg. Matrix composition did not interfere significantly with the determination of the pesticides. The obtained recoveries were,
with a few exceptions, in the range of 70–110% with RSDs less than 8%. It was applied to pesticide residue monitoring in vegetables and fruits
from local markets

Cabbage) were selected from the Supermarket to Investigate the Effect of Pesticides on different matrices and assay Precision recoveries after spiking
samples with twelve five mg / kg. Matrix composition did not interfere significantly with the determination of the pesticides. The recoveries were obtained,
with a few exceptions, in the Range of from 70 to 110% with RSDs Less than 8%. It was Applied to Pesticide residue in Vegetables and Fruits Monitoring
