Measured concentrations (mg L−1) in the aqueous phase of the test medium before (Start) and after (End) exposures.

Water samples from acute and reproduction tests as well as for the incubations providing material for RNA/gene expression assays were analyzed. The nominal concentrations are presented in brackets. Measured concentrations for reproduction tests are mean concentrations from water samples taken at three time points during the 21-d exposure in connection to water change.
