Determination of Heavy Metal Content in Wine by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)
The determination of minerals, trace elements and heavy metals in wine has a special importance both in the qualitative characterization of wines and in terms of consumers' health. At the same time, it can be an important factor in differentiating and authenticating wines based on their geographical origin. In this work is evaluated the content in heavy metals, minerals and trace elements by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), for five assortments of wines (Muscat Ottonel, Pinot Grigio, Fetească Regală, Merlot, Italian Riesling) obtained in the north-western area of Romania, in the wine-growing year 2021. Heavy metals found in the investigated wines were under the limits imposed by European standards.
