Figure 8From: Embryotoxic and proteotoxic effects of water and sediment from the Neckar River (Southern Germany) to zebrafish (Danio rerio) embryosRelative Hsp70 value of 168 hpf zebrafish larvae. Larvae were exposed to Neckar River water and sediment collected in May 2011 (A), September 2011 (B), May 2012 (C) and September 2012 (D). Relative Hsp70 value is given in relation to the mean of two internal standards. Box plots represent medians and 5th/95th percentiles. Where n < 10, no plot whiskers are shown. Asterisks indicate significant (*p < 0.05, **p < 0.01, ***p < 0.001, α = 0.05) differences between river sample treatment and negative control assessed by Steel-Dwass (nonparametric) or Tukey-Kramer (parametric) test.Back to article page
