Determination of Trace Elements Content in Mineral Water and its Processed Mineral Water by ICP-MS

Water is the most important nutrition for human health, but with the development of society more and more waters are polluted and less and less water is potable 1,2 .The pollutants include organic pollutants 3 and inorganic pollutants, such as heavy metals 4 .On the another hand, we drink not only for H 2 O but also trace elements, including K, Ca, Mg, Sr, Si and many other elements.For water safety and water nutrition, there are many mineral water brands, most which named high trace elements content and safety.But natural mineral water must meet the national standards and must be processed before sale as drinking water and the processing course can also be the pollution pathway.This paper determined the contents of trace elements and heave metals in a spring from Beijing and its processed mineral water to study the nutrition and safety of this mineral water and its processed mineral water.The natural mineral water was collected from Emei mountain of Pinggu district, Beijing city.Processed mineral water: the natural mineral water was collected from Emei mountain was filtered through quartz sand and almond carbon firstly, then filtered through carbon fiber and finally sterilized by ozone.
