[Application of ICP-MS to detection of trace elements and heavy metals in different kinds of honey].
Honey contains abundant trace elements, which are important nutritional elements for human health, but the difference between different species has not been reported. Seven kinds of trace elements and five kinds of heavy metals in different honey species were analyzed by the method of ICP-MS. The results showed that honey contained many wholesome elements, such as Ca, Fe, Zn, Mn, Cu, Se and Mo, but there was great difference between different species. The highest concentrations of Ca, Fe, Zn, Mn, Cu, Se and Mo were 132.79 micorg x g(-1) x FW (jujube flower honey), 24. 38 microg x g(-1) x FW (medlar flower honey), 4.60 microg x g(-1) x FW (balsam pear flower honey), 2930.10 ng x g(-1) x FW (balsam pear flower honey), 480. 02 ng x g(-1) x FW (lychee flower honey), 29.39 ng x g(-1) x FW (lychee flower honey) and 3. 45 ng x g(-1) x FW (medlar flower honey) respectively. Honey contains little heavy metals, the concentrations of As and Pb are below 30 ng x g(-1) FW, and those of Hg, Cd and Cr are not higher than 10 ng x g(-1) x FW. The conclusion is that honey is a wholesome and safe food.
