embryo death การใช้

These exposures often resulted in retardation of the embryo development and embryo death.
Embryo retardation did not occur in monkeys administered up to 8 times the recommended human dose but did result in embryo death.
Only in these more contaminated areas are the chemicals still having significant effects on bird populations, which continue to display abnormally high rates of developmental defects and embryo deaths.
PCBs and dioxin-like compounds have caused embryo deaths and chick deformities like crossed bills and club feet in double-crested cormorants, Caspian terns and other fish-eating birds that nest in Great Lakes colonies.
