Determination of heavy metals in different honey brands from Iranian markets

Abstract

A variety of elements are present in honey at different concentrations. Although some of these heavy metals and trace elements are useful nutrition, at higher levels they could cause health problems. In order to achieve confidence about food safety, regular monitoring of food quality is necessary. In this study, heavy metals and trace element contents were determined by inductively coupled plasma atomic emission spectrometer in 10 different honey brands from Iranian markets. All heavy metal contents in these samples were within ranges as reported in literature, except for Hg, Al and As. Compared with recommended daily intakes, it is concluded that heavy metals or trace elements intoxication following honey consumption in Iran is unlikely.
