Treatment 3: effect of arsenic on dechorionated embryos
Embryos were exposed to sodium arsenate at 5h (approximately high oblong stage) after fertilization. Concentrations of arsenic used were 50 uM, 100 uM, 200 M, 400 uM, and 800 uM. Eight chorionated and eight dechorionated embryos were placed in each solution, including a control solution of zebrafish embryo solution. Embryos were observed at several points throughout their development. All embryos appeared alive and healthy during observations, with no noticeable differences between chorionated and dechorionated embryos.
