Mortality and hatching rates during the fish embryo test. Zebrafish embryos exposed to water and sediment samples from the Argen River from sampling event 1 (a), sampling event 4 (b), and sampling event 5 (c). a Significant differences (*p < 0.05) were found between the sampling sites and the control treatment, respectively the SSB treatment. b Significant differences (*p < 0.05) between the sampling sites and the control treatment and also between the sampling sites and the SSB treatment were found for the hatching rate. c Significant differences were found between the downstream site and the control treatment, respectively the SSB treatment. The combined data of three test runs were assessed by the Cox proportional hazards survival model
