Exposure and depuration experiments for Gammarus pulex and Daphnia magna were
conducted to quantitatively analyze biotransformation products (BTPs) of organic
micropollutants (tramadol, irgarol, and terbutryn). Quantification for BTPs without available
standards was performed using an estimation method based on physicochemical properties.
Time-series of internal concentrations of micropollutants and BTPs were used to estimate
the toxicokinetic rates describing uptake, elimination, and biotransformation processes …
