As presented in Fig. 5, in the sample with the lower organic Amrubicin content (creek, TOC: 8.9 mg L−1), salbutamol was fully removed after a contact time of 60 min. However, reaction was slower compared to the other waters, which could be due to the low pH of the sample (pH 6.8). In contrast, in the case of the most polluted samples, KMnO4 is consumed by the dissolved organic matter (WWTP effluent TOC: 55 mg L−1, river TOC: 20 mg L−1) and salbutamol reaction stops at ca. 60% (WWTP effluent) and 80% (river). Besides, among the gastroesophageal sphincter TPs previously identified, only the majoritary, S-1 and S-5, were produced at concentrations high enough to be detected in all water matrices.
