Abnormal developmental morphological endpoints observed in embryonic zebrafish exposed to contaminant mixtures from extracts of LFTs deployed in the lower Willamette River, Spring 2006. Dechorionated embryos were exposed to LFT extract solution or 1% DMSO (vehicle control) in fish water at approximately 6 hours post fertilization. Representative sublethal toxic effects, observed by stereo microscope at 30 and 126 hpf, included notochord waviness (Not), pericardial edema (PE), yolk sac edema (YSE), and bent tail (T).
