3.3. DBPs and TOX concentrations of SMPs after chlorination
Concentrations of C-DBPs and N-DBPs in SMPs after chlorination under various conditions VX-765 presented in Figs. 2(A)–(D) and 3, respectively. After chlorination, several major C-DBPs including four THMs (TCM, BDCM, DBCM and TBM, Fig. 2A), one CS (CTC, Fig. 2B), five HAAs (BDCAA, TCAA, DCAA, MCAA and BCAA, Fig. 2C) and two HKs (TCP and DCP, Fig. 2D) were detected. While the species of C-DBPs formed were almost the same under different conditions, the levels of each of them were different under different conditions.
