Comparative Analysis of Contents of Four Elements in Edible Tissues of Two Kinds of Carp

By using atomic absorption spectrometry,we detected the contents of four elements(Cu,Zn,Fe,and Cd) in different edible tissues of two kinds of carp [Huanghe common carp(Cyprinus carpio Haematopterus),Songpu mirror carp(Cyprinus specularis Songpu) ].The results showed that:among different parts of muscle,the content of Cu in tail muscle was the highest,and the content of Zn in abdominal muscle was the highest.Among various organs or tissues,the contents of Cu and Fe in the cerebrum of 2 kinds of carp were all the highest,and the content of Zn in skin was the highest.The accumulative amount of Cd in various edible tissues of Huanghe common carp and Songpu mirror carp was relatively low,which was far lower than the limit of national standard.
