From: Embryotoxic and proteotoxic effects of water and sediment from the Neckar River (Southern Germany) to zebrafish (Danio rerio) embryos

Figure 6

Developmental failure rate between 60 and 96 hpf during the fish embryo test. Zebrafish embryos were exposed to water and sediment collected at the Neckar River in May 2011 (A), September 2011 (B), May 2012 (C) and September 2012 (D). Developmental failure rate is given as percentage of the observed failures divided by the total possible ones at appropriate time points. Vertical bars show the mean of two replicates. Asterisks indicate significant differences (*p < α when adjusted according to Holm-Bonferroni's method) between sampling site exposure and negative control at 96 hpf assessed by Fisher's exact test.
