Figure 4. Toxicity of dissolved inorganic selenium species to zebrafish larvae.

Figure 4

(a) Dose-response relationships for Na2SeO3, Na2SeO4, and SeCl4. Data are means ± SE of 3 replicates. In some cases, error bars are smaller than the size of the symbols. (b) Morphological endpoints of toxicity at 120 hours post fertilization (hpf) resulting from exposure to 20 μM Na2SeO3, 20 μM Na2SeO4 or 200 μM SeCl4. Morphological endpoints of toxicity include pericardial edema (pe) and yolk sac malformations (ysm).
