Leaching of Postharvest Pesticides from Lemon Fruits into Liquid Foodstuffs

This dataset supports the study “Leaching of Postharvest Pesticides from Lemon Fruits into Liquid Foodstuffs” and contains all raw measurements and processed values used to evaluate the transfer of imazalil, thiabendazole, and pyrimethanil from lemon slices into beverages and liquid foods.

Two Excel files are provided:

1. Lanyi_et_al_FC_validdata.xlsx Raw validation data for the LC MS/MS method, including calibration level peak areas, replicate injections for LOD/LOQ estimation, QC samples at three levels, and full uncertainty calculations (k = 2). All intermediate steps are included to allow independent verification of method performance.
2. Lanyi_et_al_FC_rawdata.xlsx Complete experimental dataset for the leaching study. For each matrix, raw instrument outputs (“----” for non detected peaks or numerical values) are listed exactly as exported. Three injections were performed per sample; their average gives the measured concentration in the immersion liquid. Additional parameters (pH, dry matter, alcohol content, slice masses) and all calculated values (mean concentrations, uncertainties, leaching efficiencies, Pearson correlations) are included.

Handling of values below the LOQ

Raw data remain unchanged. For injection level averages, if all three injections were
