Abstract

Instrumental neutron activation analysis technique was used for the determination of 21 trace elements in egg-yolk and egg-white of 90 farm and domestic chicken eggs. The range, arithmetic mean, geometric mean and median of each element were computed which indicate Gaussian distribution for Se, As, Sb, Cl, Fe, Zn, Na, K, Cs and In in each portion of the egg. The study indicates that the toxic elements are generally concentrated in egg-white whereas essential elements are mostly present in egg-yolk. The dietary intake of each element through farm egg was estimated and compared with daily requirement or tolerance levels.
