Investigation of the levels of some element in edible oil samples produced in Turkey by atomic absorption spectrometry

Spectrometric Determination of Copper in Edible Oil Based on the Extraction with N,N′-bis(5-methoxy-salicylidene)-2-hydroxy-1,3-propanediamine

“…Moreover, these techniques for metals determination in such organic matrix generally present some problems such as the reduced stability of the analytes in the solution, requirement of organometallic standards, the use of dangerous organic solvents or sample digestion with an acid or acid mixture (Nunes et al, 2011). Various techniques such as FAAS (Mendil et al, 2009;Nunes et al, 2011), GFAAS (Ansari et al, 2009;Cindric et al, 2007;De Leonardis et al, 2000;Matos Reyes and Campos, 2006;Mendil et al, 2009), ICP OES (Anthemidis et al, 2005;Cindric et al, 2007;Zeiner et al, 2005), ICP-MS (Llorent-Martinez et al, 2011;Pereira et al, 2010) have been used for the analysis of trace metal contents of edible oils.…”

Evaluation of cadmium, lead, copper, iron and zinc in Turkish dietary vegetable oils and olives using electrothermal and flame atomic absorption spectrometry

“…The contents of Cd, Cu, Pb, Fe and Zn in edible vegetable oils (soybean, sunflower, flower, nut, corn and olive) and in olive samples are very important for their toxicological effects on human nutrition and health because of the large amounts of these samples consumed by people as food in their daily diets (Bakkali et al, 2009;Benincasa et al, 2007;Mendil et al, 2009;Roca et al, 2000;Sahan et al, 2007). Dietary vegetable oils and olives play an essential role in human nutrition and during digestion and metabolism they may react with some chemicals, in particular with oxygen (Mendil et al, 2009).…”

“…Dietary vegetable oils and olives play an essential role in human nutrition and during digestion and metabolism they may react with some chemicals, in particular with oxygen (Mendil et al, 2009). While iron and copper are regulated as criteria for the qualities of edible olive oils and olives, lead and cadmium are considered as real pollutants reported in legislations and literature (IOOC, 2003, Bakkali et al, 2009Economic European Communities, 2006).…”

“…Cu, Fe and Zn are important for human health as essential nutrients having different biological functions in all living organisms such as increasing oil oxidation, while Cd and Pb are very important for humans due to their toxicities and metabolic roles even at low concentrations (Mendil et al, 2009;Zhu et al, 2011;Ansari et al, 2009;Guldas, 2008;Nunes et al, 2011;Sardans et al, 2010). The sources of Cd, Cu, Pb, Fe and Zn contamination in these samples might come from the soil as natural metal sources, manufacturing, packaging process and environmental pollution (Mendil et al, 2009;Zeiner et al, 2005;Benincasa et al, 2007). It is important to determine the levels ORHAN ACAR of these metals in edible oils and olives and to point out the possible contamination levels of the analytes for human health.…”

Preparation of Samples for Determining Heavy Metals Fe and Mn in Vegetable Oils: a Comparison of Different Extraction Methods

“…The concentration of metals in oil plants and, in consequence, in their production stages, depends on many factors such as the type and species of plants, type of soil they are grown in, the degree of anthropogenic pressure they are subjected to, and fertilization and hydrological conditions (irrigation) [17,18]. Additional and very important sources of metals are contaminants in food products originating from the processing in the equipment used in technological production processes, as well as vessels, containers, and packaging in which the food is stored and transported.…”
