摘要：
The article presents the results of the determination of the synthetic pyrethroid deltamethrin in raw food and various food products by gas chromatography with mass spectrometric detection (GC-MS). The stage of GC-MS determination is preceded by sample preparation using the QuEChERS method. The developed method for quantitative determination of deltamethrin by GC-MS with electron ionization (EI, 70 eV) in food products using QuEChERS is characterized by a detection limit of 0.9 mu g/kg deltamethrin and a standard deviation not exceeding 5%. The GC-MS quantitative determination of ultra-low deltamethrin content in food was performed in selected ion mode (SIM/SIR mode). The selected ions were m/z 253 (main ion) and m/z 208, 181 (confirming ions), respectively.
