n our paper, on page 9585, an error was found. The quantitative data (33 ppb, 5.5 ppb, 0) in Figure 9 were corrected. This correction does not affect any discussion and conclusions reported in the paper. The corrected figure is as follows:

Figure 9. Fluorescence spectra before and after the addition of 30 μL of the juice from CP-spiked apples. The CP residues in two batches of apple samples are 6 and 25 ppb by HPLC calibration, respectively.
