Ketamine accumulation (internal ketamine concentrations) in zebrafish embryos after static exposure to 2 mM ketamine. Embryos at 48 h post fertilization (hpf) were exposed for 2, 4 and 24 h. Post exposure, embryos were washed extensively with quick changes of embryo water three times. Reverse-phase high-performance liquid chromatography (HPLC) was employed to measure ketamine concentrations in the embryos (n = 15 per group). Data from three separate estimations were averaged and are presented as the mean ± SD.
