    Abstract:
    Twelve kinds of fish tissues were wetly decomposed and the harmful elements of Cd, As, Pb and Hg were determined by ICP-AES method in the present paper. The techniques for operating ICP instrument were optimized, spectral interference for elements in special wavelength range was studied, and the correction factor of IECs model was established. The results indicated that the signal to noise ratio and detection limit for elements with higher ionization potential energy may be improved by increasing the radio generator power properly and reducing the nebulizer pressure. There were Cr, Cu, As, Sn and Na elements that mainly disturbed the determined elements such as As (189.042 nm), Pb (220.353 nm), Cd (228.802 nm) and Hg (184.950 nm). The primary contaminating elements in tissues of freshwater fish and seawater fish were Pb and As respectively.
