AB INTRODUCTION: Honey is a natural product obtained by honey bees from flower nectar orsecretions produced by other living parts of the plants. It is also considered the result of aprocess of bioaccumulation of many metals. The amount of macro and microelements withinthe honey depends on its botanical origin and the composition of the soil in which the plantsgrow. In recent years the metal content in these plants has been related to its existence in theenvironment, being therefore used as a bioindicator. On the other hand, honey is a sweetsubstance widely used as a sweetener and natural preservative, as well as a very energeticfood product due to its high calorie content, with curative and prophylactic properties.OBJECTIVES: The objectives of this work are, first of all, to determine through ICP-OES theconcentration of 20 metals (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sr, V,Zn) contained within honeys produced in the Canary Islands and other honey molassescommercialized in the island of Tenerife. Secondly, to compare the metal content among alltypes of honeys analyzed in the sample, and contrast our results with previous studies. Andfinally, to calculate the Recommended Daily Intake (RDI) and the Acceptable Daily Intake (ADI),considering the recommended limits and maximums established by different institutions.MATERIALS AND METHODS: A total of 92 samples of different types of honeys, includinghoneys produced in the Canary Islands and commercial honeys, have been analyzed byinductively coupled plasma optical emission spectrometry (ICP-OES) following a process ofdrying, acid digestion and Incineration using muffle furnaces.RESULTS: The results obtained from the samples of honey do not reveal any significantly highvalue in terms of the contribution of the metallic intake resulting from honey consumption, forboth Canarian and commercial honeys. On the other hand, the consumption of honey by thepopulation seems to be quite limited, so we conclude that it does not imply a risk for health.
