Concentrations of eighteen major and trace elements; Na, Mg, Al, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Tl, and Pb were studied in the large icefish Protosalanx chinensis collected from four sampling areas (Yixingtan, Jiaoshan, Pingtaishan and Sanshandao) in Taihu Lake, China. This species was rich in essential elements (e.g., Na, Mg, K, Ca, Zn) and was uncontaminated with potentially toxic elements (e.g., As, Ag, and Pb). Iron levels were lower than expected. Concentrations of Mg, Al, K, Ca, Mn, Cu, Zn and Se in P. chinensis showed significant differences (P<0.05) among sampling areas, clearly revealed by principal component analysis. Moreover, the origin of P chinensis specimens from these four areas of Taihu Lake, discerned by multivariate statistical analyses, was characterized consistently by elemental fingerprint analysis (EFA). The EFA method has broad potential to identify source populations of species and fishery products in the marketplace.
