  1. Legend: n: Total number of samples, LOD Limit of detection, % >LOD: Percentage of samples with concentrations above the LOD,
  2. Min. – Max.: Minimum and maximum concentrations. Levels of statistical significance; ns Not significant, * = 0.01< p <0.05, ** = p< 0.01.
  3. Note: Arithmetic (AM) and geometric (GM) means were not calculated in cases where percentage of samples over LOD were <50%.
