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

Figure 4

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