Figure 1: Seven prioritization strategies in non-target screening (NTS) by chromatography–HRMS, grouped by domain: chemical information (P1–P3), toxicological information (P5–P6), external information (P4), and preprocessing (P2, P7). Each strategy narrows the candidate space based on specific criteria. Combined, they reduce complexity and focus identification on environmentally relevant features.
