title: [Determination of trace elements in shark cartilage by inductively coupled plasma atomic emission spectrometry].
abstract: Semiquantitative estimation of all elements in shark cartilage was investigated by inductively coupled plasma mass spectrometry (ICP-MS). The determination of trace elements, namely Fe, Zn, Se, Cu, Mn, Mo, Ti and Sr in shark cartilage, was carried out using inductively coupled plasma atomic emission spectrometry (ICP-AES). The matrix effects were overcome by using yttrium as an internal standard element. The recoveries are in the range of 81.6 to 100.7%. The determination limits of Fe, Zn, Se, Cu, Mn, Mo, Ti and Sr are 0.60, 0.55, 0.21, 0.39, 0.042, 0.27, 0.038 and 0.48 microg x g(-1), respectively. The results showed that the shark cartilage contains higher amount of Fe, Zn, Se, Cu, Mn, Mo, Ti and Sr than those in other fishes and in other animal bones.
