Detecting pesticides in food samples is a challenging task that requires efficient extraction techniques. This study aims to compare and validate two microextraction techniques, μSPEed and μQuEChERS-dSPE, for the simultaneous extraction of eight pesticides (paraquat, thiabendazole, asulam, picloram, ametryn, atrazine, linuron, and cymoxanil) from wastewater samples. A good analytical performance was obtained for both methodologies, with selectivity, linearity in the range 0.5-150 mg L^-1 with coefficients of determination up to 0.9979, limits of detection (LODs) and limits of quantification (LOQs) ranging from 0.02 to 0.05 mg L^-1 and from 0.06 Heliyone16742https://www.ebi.ac.uk/biostudies/studies/S-EPMC10241853biostudies-literatureSimultaneous microextraction of pesticides from wastewater using optimized μSPEed and μQuEChERS techniques for food contamination analysis.PMC10241853Camara JSMarina MLGarcia MAPereira JAMGarcia-Cansino LfalseSimultaneous microextraction of pesticides from wastewater using optimized μSPEed and μQuEChERS techniques for food contamination analysis.Food contamination with pesticides poses significant risks to consumer safety and undermines confidence in food supply chains.
