Refining impact on MT residues in the sunflower oils. Blank columns present contamination level below assays’ LOD 0.03 ng/mL (AFB1), 0.2 ng/mL (AOH), and 7.5 ng/mL (TEA). Dark-colored columns indicate contamination level exceeding MRL: 2.0, 10, and 100 ng/mL for AFB1, AOH, and TEA, respectively. The numbers in the columns indicate the percentages within the group
