“…In most cases, satisfactory results were obtained without any sample pretreatment [27,[47][48][49] or with a simple dilution of wine samples [9,[50][51][52], thereby enabling the direct determination of metals with little chance of contamination. Aceto et al [53] suggested the addition of nitric acid to lower pH (up to 1.5) of wine samples before their direct analysis by atomic spectroscopy techniques.…”

Metals in wine can originate from both natural and anthropogenic sources, and its concentration can be a significant parameter affecting consumption and conservation of wine. Since metallic ions have important role in oxide-reductive reactions resulting in wine browning, turbidity, cloudiness, and astringency, wine quality depends greatly on its metal composition. Moreover, metals in wine may affect human health. Consumption of wine may contribute to the daily dietary intake of essential metals (i.e., copper, iron, and zinc) but can also have potentially toxic effects if metal concentrations are not kept under allowable limits. Therefore, a strict analytical control of metal concentration is required during the whole process of wine production. This article presents a critical review of the existing literature regarding the measured metal concentration in wine, methods applied for their determination, and possible sources, as well as their impact on wine quality and human health. The main focus is set on aluminum, arsenic, cadmium, chromium, copper, iron, manganese, nickel, lead, and zinc, as these elements most often affect wine quality and human health.

“…Another way to minimize interferences by polyatomic ions in ICP-MS is the use of electrothermal vaporization (ETV) for introducing the sample into the plasma. 18,19 However, elements such as B, Mo, 20 lanthanides and actinides produce thermally stable carbides in the graphite tube, increasing the LODs.Due to the high content of organic compounds in wine, pretreatment of the sample is preferable for element determination by ICP OES and ICP-MS. The most common sample preparation procedure used is wet acid digestion or simple dilution of the sample.…”

Elementos majoritários, minoritários e traço em vinhos provenientes de países produtores na América do Sul (Argentina, Brasil, Chile e Uruguai) foram determinados. A espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES) e a espectrometria de massa com plasma indutivamente acoplado (ICP-MS) em conjunto com nebulização pneumática e/ou nebulização ultra-sônica foram utilizadas. Foram determinados 45 elementos (Al, Ag, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Dy, Er, Eu, Fe, Gd, Ho, K, La, Li, Lu, Mg, Mn, Mo, Na, Nd, Ni, P, Pb, Pr, Rb, Sb, Sn, Se, Sm, Sr, Tb, Ti, Tl, Tm, U, V, Yb e Zn) em 53 vinhos tintos. Mediante análise multivariada, os vinhos puderam ser discriminados de acordo com o país de origem, independentemente do tipo da uva. Os elementos discriminantes foram Tl, U, Li, Rb e Mg.Major, minor and trace elements in wines from wine-producing countries in South America (Argentina, Brazil, Chile, and Uruguay) were determined. Inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS) combined with pneumatic and/or ultrasonic nebulization were used. The concentrations of 45 elements (Al, Ag, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Dy, Er, Eu, Fe, Gd, Ho, K, La, Li, Lu, Mg, Mn, Mo, Na, Nd, Ni, P, Pb, Pr, Rb, Sb, Sn, Se, Sm, Sr, Tb, Ti, Tl, Tm, U, V, Yb, and Zn) in 53 red wines were determined. By means of multivariate analysis, the wines could be discriminated according to the country of origin, regardless of the type of grape. The discriminant elements were Tl, U, Li, Rb, and Mg. Keywords: red wine provenance, multivariate analysis, element concentration, ICP OES, ICP-MS IntroductionWine has a long history dating back to biblical times. With the evolution of the viticulture, a wide sort of wines became available to consumers due to the varieties of grape grown and different methods of wine producing.Several elements (especially Cd, Cu, Fe, Mn, Sn and Zn) when present in excessively high concentration in wines, adversely affect the organoleptic quality and the stability of the wine. They may cause a metallic taste, undesired color change or give rise to obstinate hazing and cloudiness. 1 The concentration of some elements can be a sort of fingerprint of the wine. The element profile does not depend exclusively on the geochemistry of the provenance soil but is affected by the winemaking process and the grape variety. Identifying the origin of wine is of great interest to producers and consumers, as it provides criteria for deciding about the quality of wine. Therefore, a method for verifying authenticity is an essential requirement to control the product origin claims.Studies have shown that the concentration profile of elements can be used to identify the provenance of a wine as well as its authenticity.2-6 Lanthanides have been suggested as a fingerprint for the provenance of wines.2,4 However, caution must be taken because contamination may occur at the production step, transport and storage, as well as by inadequate winemak...

“…Several strategies have already been employed to address spectral and non-spectral interferences caused by the wine matrix: appropriate sample pre-treatment [6], targeted optimization of the operating conditions, e.g. use of cool plasma conditions, optimizing the nebulizer gas flow rate) [7,8], the use of aerosol desolvation [8,9] or electrothermal vaporization [10], the use of mathematical equations for interference correction [11] or the use of an ICP-MS instrument equipped with a sector field mass spectrometer operating at higher mass resolution [12,13].…”

AbstractThis work explores the multi-element capabilities of inductively coupled plasma -mass spectrometry with collision/reaction cell technology (CCT-ICP-MS) for the simultaneous determination of both spectrally interfered and non-interfered nuclides in wine samples using a single set of experimental conditions. The influence of the cell gas type (i.e. He, He + H 2 and He + NH 3 ), cell gas flow rate and sample pre-treatment (i.e. water dilution or acid digestion) on the background-equivalent concentration (BEC) of several nuclides covering the mass range from 7 to 238 u has been studied. Results obtained in this work show that, operating the collision/reaction cell with a compromise cell gas flow rate (i.e. 4 mL min -1 ) improves BEC values for interfered nuclides without a significant effect on the BECs for non-interfered nuclides, with the exception of the light elements Li and Be. Among the different cell gas mixtures tested, the use of He or He + H 2 is preferred over He + NH 3 because NH 3 generates new spectral interferences.2 No significant influence of the sample pre-treatment methodology (i.e. dilution or digestion) on the multi-element capabilities of CCT-ICP-MS in the context of simultaneous analysis of interfered and non-interfered nuclides was observed.Nonetheless, sample dilution should be kept at minimum to ensure that light nuclides (e.g. Li and Be) could be quantified in wine. Finally, a direct 5-fold aqueous dilution is recommended for the simultaneous trace and ultra-trace determination of spectrally interfered and non-interfered elements in wine by means of CCT-ICP-MS. The use of the CCT is mandatory for interference-free ultra-trace determination of Ti and Cr. Only Be could not be determined when using the CCT due to a deteriorated limit of detection when compared to conventional ICP-MS.
