This study was carried out to quantify 11 trace minerals including Ca in wild duck egg, focused on health-aid-food, with Inductively Coupled Argon Plasma Atomic Emission Spectrometry(ICAPS). It showed the highest levels of P, Fe, Zn and Cu in egg yolk compared with those of another constituents in wild duck egg. In egg white, the trace mineral levels were demonstrated K 1096 ppm, Na 1666 ppm, respectively. Therefore the levels of K, Na are considerably high. The contents of Ca and Mg are conspicuously high in egg shell respectively. The essential minerals such as Co, Cr and Mn were trace in all constituent of wild duck egg, respectively.

ABSTRACT-The study was to investigate the residue of the harmful heavy metals in the random samples of feed from piggery, formula feeed for swine and ingredient feed from feed mill and analyzed for Cd, Pb and As by using Atomic Absorption Spectrophotometer and Inductively Coupled Argon Plasmas. Mean concentrations of Cd, Pb and As (ppm) were, for feed from piggery 1.08-0.85, 5.34-4.29 and 4.30-2.37, for formula feed from feed mill, 0.90-0.51, 5.84-5.25 and 2.41-0.84, and for ingredient feed from feed mill, 0.35-0.38, 4.38-4.94 and 2.66-1.12, respectively. It showed the highest amount of Cd, Pb and As in kidney and liver than in the other organs, and the lowest amount in the muscle.muscle.
