This article reviews methods for the determination and identification of trace elements in wine by using atomic absorption spectrometry (AAS). Wine is one of the most widely consumed beverages and strict analytical control of trace elements content is required during the whole process of wine production from grape to the final product. Levels of trace elements in wine are important from both points of view: organoleptic – Fe, Cu, Mn and Zn concentrations are directly related to the destabilization and oxidative evolution of wines, and toxicological – toxic elements content should be under the allowable limit, wine identification. The identification of metals in wine is subject of increasing interest since complexation may reduce their toxicity and bioavailability. AAS is one of widely used methods for routine analytical control of wine quality recommended by the International Organization of Vine and Wine. Two main approaches – preliminary sample digestion and direct instrumental measurement combined with AAS for trace element determination in wines are reviewed and discussed. Procedures for various sample pretreatments, for trace element separation and preconcentration are presented. Advances in metal identification studies in wines based on AAS are presented.

Abstract The determination of trace elements in food and soil samples by atomic absorption spectrometry was investigated. A coprecipitation procedure with holmium hydroxide was used for separation- preconcentration of trace elements. Trace amounts of copper(II), manganese(II), cobalt(II), nickel(II), chromium(III), iron(III), cadmium(II), and lead(II) ions were coprecipitated with holmium hydroxide in 2.0 M NaOH medium. The optimum conditions for the coprecipitation process were investigated for several commonly tested experimental parameters, such as amount of coprecipitant, effect of standing time, centrifugation rate and time, and sample volume. The precision, based on replicate analysis, was lower than 10% for the analytes. In order to verify the accuracy of the method, the certified reference materials BCR 141 R calcareous loam soil and CRM 025-050 soil were analyzed. The procedure was successfully applied for separation and preconcentration of the investigated ions in various food and soil samples. An amount of the solid samples was decomposed with 15 mL concentrated hydrochloric acid–concentrated nitric acid (3 + 1). The preconcentration procedure was then applied to the final solutions. The concentration of trace elements in samples was determined by atomic absorption spectrometry.

The aim of our study was to determine the trace elements content (Mn, Fe, Zn, Cu, Cr, Pb, Ni, Co, and Cd) in Vaccinium vitis-idaea leaves grown in the light-coniferous forests of Ikatskiy range. Element content was measured by atomic absorption spectrometry (AAS,AAnalyst 400 PerkinElmer). Results obtained indicated that the metals concentrations in the leaves ranged from 0,05 (Cd) to 576 (Mn) ppm. The row of the elements accumulation in the leaves is: Mn > Fe > Zn > Cu > Cr > Pb >Ni ≥ Co >Cd.According to the coefficients of accumulation leaves acted as accumulators of Mn, Cu, Zn (CA > 1) and excluders of Fe, Cr, Ni, Pb, Co, Cd (CA < 1). Significant correlations were found between content acid-soluble forms Cr, Mn, Fe, Cu in the soil and leaves (r = 0,48–0,76). The toxic trace element (Pb, Cd) analysis demonstrated that their content was safe for human consumption.
