Abstract
|
|
|
The concentration of heavy metals in 12 eggs collected from 6 nests of Intermediate Egret, Egretta intermedia intermedia from Ogjong-myun, Hadong-gun, Kyungnam, was examined by atomic absorption spectrophoto-meter method in 1983.
It was found that heavy metals are contained in their eggs with highest concentration Cd and Cu in the eggshell and Cr, Zn, Pb and Mn in the yolk, respectively.
The thin-shelled group, bu their eggshell thickness grouping, contained heavy metal in higher amount than that of thick eggshelled group. And the thin group showed small values in weight of individual egg, its yolk and albumen.
