The concentrations of PAH analytes and presence of other chemicals of concern in exposure solutions composed of 1% PSD extract obtained from sites within the Portland Harbor Superfund are shown. Examples of developmental abnormalities in 5 day post fertilization (dpf) embryos exposed to PSD extract solutions include mortality, yolk sac edema (YSE), pericardial edema (PE) and malformations of the body axis, trunk, notochord (NOT), jaw and snout. Normal development in an embryo exposed to the vehicle control is also pictured. Not all deformities pictured are labeled.
