Abstract OBJECTIVE: To investigate the contents of forty-four elements in the common fruits grown in Shaoxing.METHODS: The determination of 44 elements in 216 samples of ten kinds of fruits from Shaoxing was performed by national standard for food safety GB 5009. 94-2012 and GB 5009. 268-2016. Macroelements(K, Ca, Na, Mg), microelements(Li, B, Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Ag, Cd, Sn, Sb, Ba, Hg, Tl, Pb) and rare earth elements(Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) were analyzed and discussed.RESULTS: The fruits were rich in K, Mg and Ca with the median value of 1673. 28, 93. 76 and 56. 80 mg/kg, respectively, and the contents of K, Mg and Ca in Actinidia were the highest among all kinds of fruits, with the median value of 2932. 87、193. 91 and 253. 77 mg/kg, respectively. The contents of microelements(Fe, B and Mn) in fruit were relatively high, the detection rate was 100. 0%, and the median value was 2. 31, 2. 27 and 1. 41 mg/kg, respectively. The contents of Sb, Li, As, Hg, V, Se and Ag were very low with the detection rates below 20. 0%. The contents of 16 kinds of rare earth elements in all kinds of fruits were low with the detection rates below 50. 0% except Ce.CONCLUSION: The fruits planted in Shaoxing are rich in macroelements(K, Ca and Mg) and microelements(Fe, B and Mn), the pollution of toxic elements(Pb, Cd, Hg and As) are not serious, cadmium(Cd) in 13. 8% of strawberry is excess compared with the maximum levels of contaminants in foods(GB 2762-2017) and the contents of the 16 rare earth elements are very low.
