Concentration (ng/g) of recovered steroid throughout egg compartments on days six and nine of embryonic development. Polar (Conj.) and apolar (Free) steroids were extracted from the yolk, albumen, and embryo and the concentration of recovered steroid was calculated (n=8 per day per dose; 6 day Low dose(6dL), 6 day Medium dose (6dM), 6 day High dose (6dH), 9 day Low dose (9dL), 9 day Medium dose (9dM), 9 day High dose (9dH)).
