[Investigation of the content of multiple elements in the fruit planted in Shaoxing]

To investigate the contents of forty-four elements in the common fruits grown in Shaoxing.

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.

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.

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.
