Abstract The contents of macroelements（ Na,Mg,Al,K,Ca,56 Fe and Zn） and microelements（ V,Cr,Mn,As,Se and 206Pb） were detected in Antarctic icefishes Chionodraco hamatus（ CH） and Trematomus bernacchii（ TB） using inductively coupled plasma mass spectrometry（ ICP-MS） method in order to compare the element concentrations of hemoglobinless between Antarctic icefish CH and TB. Results showed that there were significant differences in concentrations of Al,K,56 Fe,Se and Mn in the vertebrae and significant differences in concentrations of Mg,K,Ca,56 Fe,V and Mn in the skull between CH and TB（ P〈0. 05）,which might be attributed to the functional red blood cells shortage in the Antarctic icefish. The comparison of element concentrations in vertebrae between the two Antarctic icefishes and seven non-Antarctic marine fishes and three freshwater fishes revealed that there were much lower levels of macroelements K,Na,Mg,56 Fe,Zn,and Ca in skeletons of the two Antarctic icefishes,significantly lower levels of microelements Mn,V,Cr and 206 Pb in the two Antarctic fishes than those in the non-Antarctic fishes,which is involved in much lower contamination in the Antarctic marine environment. The first insight into element concentration of the two Antarctic fishes will provide some scientific basis for the physiological difference comparison in Antarctic icefishes through tissue element analysis.
