Determination of Heavy Metals and Trace Elements in Selenium-enriched Cherry Fruit by ICP-MS

摘要

To investigate the food safety and nutritional characteristics of cherry fruits after spraying the Se-enriched foliar fertilizer. Nine kinds of heavy metals and seven kinds of beneficial trace elements in Se-enriched cherry fruits and normal cherry CK (not applying Se-enriched foliar fertilizer) were determined by ICP-MS. The results showed that (1) selenium can reduce the contents of heavy metals (Pb, Cu, Cr, Ni, Cd and V) in fruits of Cherry; (2) selenium-enriched foliar fertilizer can promote the absorption of other trace elements (K, Ca and Fe) in addition to increasing the selenium content in fruit of cherries. So selenium fertilizer can increase nutrition of fruits and reduce the harm of fruits.
