[Determination of Ca, Mg, Pb, Cd, As and Hg in the feather of Japanese crested ibis].

Trace elements participate in many important life processes of Japanese crested ibis. A method of simultaneous and direct determination of Ca, Mg, Pb, Cd, As and Hg in the feather of Japanese crested ibis by ICP and HG-AAS is reported. The results show that the method has good precision and accuracy. The recovery is 95%-105%. A long term track of trace elements contained in Japanese crested ibis, particularly the collection and study of the data concerning harmful trace elements, is significant to the improvement in the growth and breeding of the species.
