IHSS&IWA26 / BRNO / CZECHIA / 23–28 August 2026 BOOK OF ABSTRACTS 24 Analysis and Characterization Monday, 24 August 2026 / Hall B+C components and DBPFP (r ≈ 0.6–0.8), whereas correlations between NDBPFP and protein-like components were more variable among individual compounds. The combined use of occurrence data, fluorescence‑based DOM characterization, and DBPFP testing provided enhanced insight into DOM reactivity and DBP risk across treatment processes. These findings support the value of DOM fractionation as a complementary tool for understanding and managing DBP formation in drinking water production which will be essential for anticipating future DBP risks under climate‑driven changes in source water quality and increasing eutrophication pressure.
