บทคัดย่อ

Twenty one days after injecting 0.1 ml solution containing 0.010, 0.015, 0.020, 0.025, 0.030, 0.035, 0.040, 0.045 and 0.050 mg cadmium to fertile chicken eggs, it was found that injection of 0.030 mg inhibited hatching of the eggs. With regards to the distribution of 0.030 mg cadmium, five days after injection into fertile chicken eggs, 94% was in the embryo and 4% in egg yolk plus albumin. However, the amount of cadmium in egg shell was not detectable. Determination of cadmium in each sample was done by atomic absorption spectrophotometry.
