Mortality during the fish embryo test. Zebrafish embryos were exposed to the Neckar River samples collected in May 2011 (A), September 2011 (B), May 2012 (C) and September 2012 (D). Asterisks show significant differences (*p < 0.05, **p < 0.01, ***p < 0.001, α = 0.05) between sampling site exposure and negative control. Combined data of two replicates was assessed by the Cox proportional hazards survival model.
