Investigation of insecticide residues in potato grown in Türkiye by LC-MS/MS and GC-MS and health risk assessment

Insecticide, acaricide, nematicide and metabolite residues were assayed in 104 potato samples collected from local markets Tokat, Türkiye 2022 the potential health risk for consumers assessed. Analytical method verification was performed 135 pesticide active substances matrices by liquid chromatography-tandem mass spectrometry gas chromatography-mass spectrometry. Matrix-matched calibration curves constructed good linearity obtained with a coefficient of determination between 0.990 0.999. Average recoveries varied 73.2 to 119.6%. Repeatability intra-laboratory reproducibility conditions expressed as %RSD less than 20%. These figures within SANTE/11312/2021 recovery limits (70-120%) values specified repeatability (RSD ? 20%). The quantification lower maximum residue set European Union potato. No found at detectable 93 samples. Two contained below limit (MRL), while nine above MRLs. Clothianidin thiamethoxam detected one sample, acetamiprid assessment study indicated that consumption safe consumers.
