Evaluation of the TH and the analogue conjugations by LC–MS/MS in STP samples collected in the Sapporo city during May 2022 (Site3_May). Raw sample was not deconjugated. The enzyme-treated sample was deconjugated using β-glucuronidase/arylsulfatase liquid enzyme. The error bar represents standard errors (n = 3).
