To analyze the contents of Ca, K, Na, Mg, Fe, Zn, Cu and Mn in 33 kinds of marine products, such as fish, shrimp, crab, shellfish and mollusk.The national standard GB 5009. 268-2016 Determination of multi elements in foods was used for determination. The correlation between multi elements was statistically analyzed.The highest level of Ca was found in clam(510. 2 mg/100 g edible), K in mackerel(444. 4 mg/100 g edible), Na in clam(487. 6 mg/100 g edible), Mg in conch(132. 7 mg/100 g edible). The highest level of Fe and Mn was in conch(37. 35 and 2. 6 mg/100 g edible). The highest level of Zn and Cu was in oyster(15. 92 and 8. 58 mg/100 g edible). The correlation analysis showed that Mn-Ca was highly correlated in fish and shrimp(r=0. 9438 and 0. 8585, P < 0. 05), while Cu-Mg, Cu-Zn, Zn-Na were highly correlated in shellfish(r=-0. 9102, 0. 8501 and 0. 8428, P < 0. 05).There are rich mineral elements in different seafood, which can provide reference for the reasonable diet of residents.
