“…The volatile organic solvents have been directly introduced into ICPs for many years, but this can cause plasma instability, less sensitivity, less precision and high cost. Al, Cr, Cd, Cu, Fe, Mn, Ni and Pb contents of olive oil were investigated using diethyl ether, methyl isobutyl ketone (MIBK), xylene, heptane, 1,4-dioxane as solvent and N,N-hexamethylenedithiocarbamic acid, hexamethyleneammonium (HMDC-HMA) salt as a modifier by ETAAS (Karadjova et al, 1998). A transverse heated filter atomizer (THFA) was employed for the direct determination of Cd and Pb in olive oil after sample dilution with nheptane (Canario & Katskov, 2005).…”

“…No obstante, las técnicas que actualmente ofrecen una mayor sensibilidad para la determinación de metales son las técnicas atómicas, y entre ellas se encuentran la espectroscopía de absorción atómi-ca con atomización electrotérmica (EAA-AE) (Allen et al, 1998;De Leonardis et al, 2000;Lendinez et al, 2001;Zeiner et al, 2005;Matos Reyes y Campos, 2006), la espectroscopía de emisión atómica con plasma acoplado inductivamente (ICP-AES), (Zeiner et al, 2005;Juranovic Cindric et al, 2007;Pehlivan et al, 2008), sin olvidar la determinaciones multielementales mediante espectroscopía de emisión atómica con plasma acoplado inductivamente-espectrometría de masas (ICP-MS) en aceitunas de mesa (Sahan et al, 2007), aceites de oliva (Benincasa et al, 2007) y vegetales (Chang y Jiang, 2008). En el caso de la determinación por EAA-AE se han propuesto algunas metodologías en las cuales las muestras de aceites se disuelven previamente en metil isobutil cetona (Martín-Polvillo et al, 1994), lecitina-ciclohexano (Chen et al, 1999) o en una disolución de ácido N,N-hexametilenoditiocarbamico-sal de hexametilenoamonio (Karadjova et al, 1998).

A simple, rapid analytical method for determining traces of Cd, Cr, Cu, Mn and Pb in in various types of vegetable oils is proposed. Samples are digested in a microwave oven and then analyzed by atomic absorption spectroscopy with electrothermal atomization. The proposed method exhibits good linearity and sensitivity to the five metals, which it can determine with detection limits over the range 0.06-2.15 Ìg/kg. Its precision, as relative standard deviation, ranges from 2.6 to 4.2%. Its accuracy was assessed by using it to analyze a reference material consisting of Used Oil HU-1, which contains certified metal concentrations, and was found to be quite acceptable. The proposed method was applied to the determination of the five metals in virgin olive, olive, sunflower, maize and pomace olive oils from Spain and Morocco. Based on the results, the metal contents varied among oil types and, for olive oil, also with the country of origin; the oil samples from Morocco contained especially high levels of lead.

En el presente trabajo se propone un método simple y rápido de análisis para la determinación de trazas metálicas (Cd, Cr, Cu, Mn, y Pb) en diferentes tipos de aceites vegetales. El procedimiento consiste en el tratamiento previo de la muestra mediante digestión con horno de microondas y en el análisis mediante espectroscopía de absorción atómica con atomización electrotérmica. El método ofrece una buena linealidad y sensibilidad para los cinco metales determinados, con límites de detección comprendidos entre 0,06- 2,15 μg/kg. La precisión del método expresada como desviación estándar relativa oscila entre 2,6 y 4,2 %. Para el estudio de la exactitud se analizó un aceite de referencia (Used Oil HU-1) con las concentraciones de metales certificadas, obteniéndose unos resultados satisfactorios. La metodología desarrollada se aplicó a la determinación de metales en diferentes tipos de aceite vegetales (oliva virgen, oliva, girasol, maíz y de orujo) de distinta procedencia (España y Marruecos). Los resultados obtenidos han puesto de manifiesto que el contenido de metales depende del aceite analizado, y en el caso del aceite de oliva varía dependiendo del país de procedencia, obteniéndose unos valores elevados para el plomo en las muestras producidas en Marruecos

“…In general, the inorganic elements in food and drinks might originate from the soil and fertilisers, the equipment containers and utensils used for food processing, storage or cooking and the industrial activity (MUNTEAN et al, 1998;KARADJOVA et al, 1998). Sometimes the inorganic elements might also originate from water, which is used for dilution of the distillate.…”

Tsipouro and Tsikoudia are two denominations with geographic indications of the traditional Greek marc distillate, which is produced in continental Greece and in the island of Crete respectively. It is produced by the Greek winegrowers as well as by the professional distillers. To provide data on the safety of domestic Tsipouro and Tsikoudia distillates for human consumption and to draw conclusions from any essential results, which might have an impact on the quality of this product, 23 samples were analysed for: (a) Volatile compounds by the use of gas chromatography, (b) Inorganic elements, using atomic absorption spectrometry and (c) the pH values through-out using standard methods. Data revealed differences between these two denominations, which have been confirmed by the application of a statistic analysis and a PCA. Thus, Tsikoudia was found to contain statistically higher amounts of acetalde-hyde. However, the levels that have been observed did not exceed the official limits. Most of the Tsipouro and Tsikoudia samples also contained low concentrations of estragol, an anise compound, lead and copper, which do not represent a risk to consumer health due to their toxicity. On the other hand, the total concentration of higher alcohols was higher than the official minimum limit (140 g.hl -1 Absolute Alcohol-AA), while the amylic alcohols rarely exceeded 300 g.hl-1 AA. The high concentrations of ethyl acetate (>300 g.hl -1 AA) and ethyl lactate in a few samples showed the necessity of limiting unwanted fermentations in the grape pomace. The analytical study showed that the quality of the marc distillate is, generally, satisfactory. However, it revealed great differences between Tsipouro and Tsikoudia even among the samples of each denomination and, con-sequently, these domestic distillates need standardization and a more systematic production.Résumé: « Tsipouro » et « Tsikoudia » sont deux dénominations du distillat grec de marc, avec des indications géogra-phiques, produit en Grèce continentale et à l'île de Crète respectivement. Il est produit par les vignerons grecs ainsi que par les distillateurs professionnels. Afin de fournir des données concernant l'influence (la sûreté) de Tsipouro et de Tsikoudia produits par les vignerons sur la santé des consommateurs et de tirer des conclusions de certains résultats essentiels, qui pourraient avoir un impact sur la qualité de ce produit, 23 échantillons ont été analysés en dosant: (a) les composés volatils à l'aide de la chromatographie en phase gazeuse, (b) les éléments inorganiques, en utilisant la spectrométrie par absorption atomique et (c) les valeurs du pH, en utilisant des méthodes standards. Les données ont indiqué des différences significatives entre ces deux dénominations, qui ont été confirmées par la statistique et l'application de l'ACP. Les échantillons de Tsikoudia se sont avérés avoir des concentrations statistiquement plus élevées en acétaldéhyde. Cependant, les niveaux qui sont observés n'ont pas dépassé les limites officielles.
