Developmental delay in zebrafish embryos exposed to 2′-OH-6′-Cl-BDE68. Images of 48 hpf old embryos exposed to different concentrations (upper row). The delayed embryos look like control embryos at 11 and 20 hpf (lower row). Magnification was 2×.

Effects on growth of zebrafish embryos exposed to a mixture of OH-PBDEs for 24 h. The concentrations of the test compounds in the mixture were modelled to represent levels found in Baltic blue mussels, and were tested as concentrated mixtures (10X and 100X) or diluted mixtures (10× and 100×). The error bars show the standard deviation over three replicates.
