1. A Cu conc of 19.2 mg/L was measured in the eluate and 22 in the pH experiments. The modelling is based on the concentration of 22 mg/L.
2. TU-values are calculated by dividing measured concentrations in a sample by its respective EC 50 -values. These TU-values can be calculated for all toxicants together and added together to provide an overall insight in the expected toxicity. As a consequence, if a sample exceeds the TU-value of 1, it might be expected that > 50% effect will occur.
