Abstract: The analysis and evaluation of inorganic elements in Sargassum pallidum and Sargassum fusiforme from different regions provide may theoretical evidences for formulating harmful elements limit standards and comprehensive utilization of sargassum. The contents of 30 inorganic elements in Sargassum from different regions were determined by ICP- AES and iodine ion- selective electrode after ashing and digestion. Principal component analysis was carried out to evaluate Sargassum samples. The results showed that Sargassum from different regions contain 19~26 inorganic elements, with the average contents K>Ca>Na>Mg. The mean values of Cu, Hg, Pb, Cd, As and Al are 7.83, 1.54, 3.07, 3.02, 109.35, and 1434.26 mg/kg, respectively. No significant difference between S. pallidum and S. fusiforme was found in most elements. Principal component comprehensive scoring showed Samples H₄ and H₃ of S. pallidum from Yantai and Samples Y₅ and Y₆ of S. fusiforme from Wenzhou are the top four, indicating that these regions have better S. pallidum and S. fusiforme in terms of inorganic elements.

Key words： Sargassum pallidum Sargassum fusiforme sargassum inorganic elements
