title: [Application of ICP-MS to the detection of forty elements in wine].
abstract: With the rapid development of wine, more and more people begin to pay more attention to its ingredients. Four kinds of wine were studied by ICP-MS to detect the heavy metals and microelements. The results showed that the wine contained many elements necessary to human health: 7 kinds of macroelements and 29 kinds of microelements. The sequence of macroelements is K>P>Mg>Ca>Na>Al approximately Si. The concentration of K is more than 900 microg x mL(-1), sometimes reaching 2359 microg x mL(-1) (shelongzhu). Six kinds of elements (Rb, Mn, Sr, Zn, Fe and Ba) among 28 kinds of microelements are higher than 200 ng x g(-1), and some elements are more than 1000 ng x mL(-1) (Rb, Mn and Sr), which is important to human health. In addition to microelements, contents of heavy metals (As, Cr, Pb and Cd) are also an important standard to identify the quality of wine, and the results showed that wine contains little heavy metals, whose sequence is As (less than 50 ng x g(-1))>Cr>Pb>Cd. All the data showed that the wine meets the national hygiene standards.
