Boxplots (mean = dashed, median = solid) of the temperature increase at 50 W, 6 s for the red clover plant samples of the two MWCNT treatments (3 and 2933 mg/kg). The LOD (at ΔT = 76 °C, corresponding to 16 μg/g) is indicated with the red dashed line and the LOQ (at ΔT = 117 °C, corresponding to 55 μg/g) is indicated with the solid red line. Both LOD and LOQ have been determined 3 and 10 σ above the blank signal (control plants), respectively. All seven replicates of the treatments have been measured at least twice. The total number of measurements is indicated above the respective boxplot. The lower and upper borders of the boxes represent the 25th and 75th percentile, respectively. Whiskers represent maximum and minimum values
