7 2 : (Protosalanx hyalocranius) 207 BIOACCUMULATION OF ELEMENTS IN ICEFISH PROTOSALANX HYALOCRANIUS FROM THE TAIHU LAKE AND HONGZE LAKE YANG Jian 1, XU Xun 2, LIU Hong-Bo 1 (1. Key Laboratory of Ecological Environment and Resources of Inland Fisheries, Freshwater Fisheries Research Center, Chinese Academy of Fishery Sciences, Wuxi, ; 2. College of Fisheries, Nanjing Agriculture University, Wuxi, ) Abstract Icefish Protosalanx hyalocranius is an important commercial fish in freshwater lakes of China. Research on bioaccumulation of mineral and trace elements in this fish is however very limited. Bioaccumulation of 12 elements in 19 P. hyalocranius individuals from the Taihu and Hongze Lake in Jiangsu Province, China are studied with ICP-MS (inductively coupled plasma mass spectroscopy). Results show that the concentration ranges of elements in the fish collected from the two lakes are: calcium (Ca), ; sodium (Na), ; magnesium (Mg), ; potassium (K), ; zinc (Zn), ; manganese (Mn), ; selenium (Se), ; copper (Cu), ; arsenic (As), ; iron (Fe), non-detectable (n.d.) 24.19; cobalt (Co), n.d mg/kg dry weight; and cadmium (Cd), n.d. Except for Fe, P. hyalocranius seems to be rich in essential elements generally, especially Ca, Mg, and Zn. The concentrations of Na, K, Cu, As, and Se in the Taihu Lake fish samples are significantly higher than those in the Hongze Lake, while the Ca, Mg and Zn concentrations are significantly higher in the latter. Principal component analysis reveals clear geographic differentiation in holistic elemental accumulation patterns in samples of the two lakes. A linear discriminate analysis function has been established based on the element concentration patterns to discriminate them between the two lakes and the discrimination rate reached 100%. In addition, As, Cd, Cu and Se residuals are well below the levels of the national standards for foods (NY and GB ). Therefore, the fish shall be safe for human consumption.
