The average (AVG) represents the concentration of positive samples per pesticide. The limit of quantification (LOQ) was established at 0.019 mg/kg for the herbicide 2,4-D, while for the remaining compounds, it was set at 0.010 mg/kg. Pesticides found in honey are highlighted in bold, while the remaining data corresponds to analytes detected in pollen.
