Schematic overview of the workflow of this study analogous to the concepts of a Toxicity Identification Evaluation (TIE). The numbered boxes represent the steps that were conducted in this study. Identification of predominant pollutant class(es) corresponds to phase 1 of a TIE and is necessary in cases where no background data are available (e.g., as illustrated by Burgess et al. [18]). The dashed arrow represents step 6 of the workflow, i.e., comparing the effects between field and reconstituted exposure scenarios.
