Nrf2, AhR, and ER relative activities (fold change vs. vehicle control) observed at REF 50 for the full-scale process vs. the pilot-scale A and B treatment processes in November 2019 (A, D, G), in May 2020 (B, E, H), and in September 2020 (C, F, I). Treatment groups (n = 4) were normalized to the vehicle control (n = 8) set to 1. The dotted lines represent the respective cut-off levels. Data presented as mean ± standard deviation. For comparison’s sake, the bioactivities for SF have been repeated for all treatment processes in panels A, B, D, E, G, and H
