摘要：
Application of elemental metabolomics for geographical origin determination is presented. Elemental transportation to food is shown. Guidelines and pitfalls are elucidated. New studies assess a vast number of elements with special mention to ultra trace elements, mainly rare earth elements, and isotope ratios of heavy elements. High resolution inductively coupled plasma mass spectrometry will be important in the future. Although there is a clear link between soil and plant products, the link between soil-plants-animal products is more complicated. Food processing steps increase complexity and they should be studied. Future studies should account for seasonality, climate, pollution, contact materials and organism's age. Adequate number of samples is another important factor for reasonable explanation of the relation of elemental content to geographic origin.
