Determinazione dei principal! componenti minerali presenti nell'olio essenziale di bergamotto cold pressed

The mineral components distribution of cold pressed bergamot essential oils was investigated by three different Atomic Spectrometry techniques. Ag, Al, Ba, Be, Co, Cu, Cr, Fe, Mn, Ni, Tl, Sb, and Sn were quantified by ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry), while GFAA (Graphite Furnace Atomic Absorption) and FI-M/H-AAS (Flow Injection Analysis-Mercury Hydride System) were adopted for the determination of lead, cadmium and mercury. Aluminium, tin and zinc were the elements with greatest concentration present in the analyzed samples with an average content of 955, 582 and 418 μg/Kg, while iron, barium and manganese assessed on average contents of 269, 104 and 88 μg/Kg. Nickel and copper assessed on average contents of 17 and 29μg/Kg, while the average content of lead, manganese and zinc was 46, 88 e 418 μg/Kg respectively In all the analyzed samples the cobalt, beryllium and mercury concentrations were result lower that limits of quantification, while the cadmium was present to an average concentration of around 4 μg/Kg.
