used in traditional medicines. Medaka (Oryzias latipes) embryos were exposed to 0.001–10
µM concentrations of MeHg, HgCl2, α-HgS (Zhu Sha), and β-HgS (Zuotai) from stage 10 (6–
7 hpf) to 10 days post fertilization (dpf). Of the forms of mercury in this study, the organic form
(MeHg) proved the most toxic followed by inorganic mercury (HgCl2), both producing
embryo developmental toxicity. Altered phenotypes included pericardial edema with …
