Table 23: Ceriodaphnia dubia reproduction after 7 d: EC20 [%] for number <strong>of</strong> <strong>of</strong>fspring (95% confidence interval in brackets) <strong>and</strong> change index (CI) for the<br />

poudre - Ultrafiltration. n.t. not toxic, n.m. not measured. If e.g. only the influent sample was toxic, a surrogate EC20 <strong>of</strong> 110% (as the “real” value is >100%) was<br />
used for the not toxic samples in order to be able to calculate a change index.<br />
