### Method Validation Results
The repeatability of the method was assessed after analyzing 10 samples in one day. For most of the compounds, the RSD values ranged between 6 and 20% at 0.03 \(\mathrm{\SIUnitSymbolMicro g}\)/g concentration level and between 3 and 20% at 0.1 \(\mathrm{\SIUnitSymbolMicro g}\)/g concentration level. Repeatability values for all the analytes are presented in Table 1. LODs and LOQs were calculated and found to be in the ranges 0.005-0.014 \(\mathrm{\SIUnitSymbolMicro g}\)/g and 0.010-0.030 \(\mathrm{\SIUnitSymbolMicro g}\)/g, respectively, as presented in Table 1. The precision of the method was evaluated in terms of reproducibility at the 0.1 \(\mathrm{\SIUnitSymbolMicro g}\)/g concentration level. Table 1 presents the average recoveries from the four repetitive applications of the method over a period of one month and their RSD%. Overall, the results are considered satisfactory. \begin{table}
