“…At the opposite end phenanthrene, fluoranthene and pyrene were detected in 100% of the samples, and these compounds were also found at the highest concentrations in yogurts of both types of production, with similar median values (Table 4). Our results were in agreement with the scarce data that are currently available for PAHs content in dairy products (Bordajandi et al 2004;Falco et al 2003;Kim et al 2008;Çok et al 2012;Veyrand et al 2013) or in similar matrices such as human breast milk (Kim et al 2008;Çok et al 2012). We considered very interesting to focus our study on the group of eight PAHs that have been signalled by the EFSA as the most worrying (PAH8; (benzo (Table 4), which appeared with similar frequencies between samples of both production methods.…”

“…When we used the TEQ approach as defined by the WHO in 2006 (Van den Berg et al 2006) the median values obtained were 0.16 pg TEQ g −1 fat and 0.08 pg TEQ g −1 fat in conventional and organic brands, respectively. These values can be considered as low, or at least much lower that those described by EFSA (2012) or other independent studies (Bordajandi et al 2004;Malisch & Dilara 2007;Esposito et al 2009). Although the median values of PCBs reported in our study are well below the established limits (40 ng g −1 fat for M-PCBs and 2.5 pg WHO-TEQ/g −1 fat for DL-PCBs, Table 2), it should be highlighted that the DL-PCB content of several samples widely overpassed these limits.…”

In the present study we have quantified the levels of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in commercially available brands of yogurt (17 conventional and 15 organic) present in the Spanish market, with the goal of estimating the daily intake of these contaminants by the Spanish population through the yogurt consumption. On the one hand, with respect to organochlorine contaminants (OCPs and PCBs) our results showed that hexachlorobenzene, p,pʹ-DDE, and all the PCBs congeners that are considered markers of environmental contamination were present in almost all the yogurt samples. The concentrations of these pollutants were found to be very low [well below the toxicological standard limits established by the European Union (http://ec.europa.eu/sanco_pesticides/public/?event=homepage)] in almost all the samples, but were even lower in organic than in conventionally produced yogurts. It is remarkable that in some of the samples (six conventional and three organic yogurts) the current maximum level for dioxin-like PCBs (2.5pg WHO-TEQ/g −1 fat) was exceeded. On the other hand, with respect to PAHs, the mutagenic and carcinogenic compounds benzo[k]fluoranthene, benzo [b]fluoranthene and chrysene were frequently detected in yogurt. From these results we have estimated that the daily intake of these pollutants is in general low. However, it should be highlighted that if the consumer inadvertently choose certain yogurts they could be exposed to high amounts of certain pollutants, that could be even higher than the tolerated daily intakes established by the European Union.

Enantiomeric separation of chiral polychlorinated biphenyls on β-cyclodextrin capillary columns by means of heart-cut multidimensional gas chromatography and comprehensive two-dimensional gas chromatography. Application to food samples

Three commercially available chiral capillary columns, Chirasil-Dex, BGB-176SE, and BGB-172, have been evaluated for the separation into enantiomers of the 19 chiral polychlorinated biphenyls (PCB) congeners stable at room temperature. The enantiomers of 15 chiral PCBs were, at least to some extent, separated using these beta-cyclodextrin based columns. Multidimensional techniques, such as heart-cut multi-dimensional gas chromatography (heart-cut MDGC) and comprehensive two-dimensional gas chromatography (GC x GC), were investigated for their ability to solve coelution problems with other PCBs present in commercial mixtures and real-life samples. Heart-cut MDGC improved the separation as compared to one-dimensional GC, and enantiomeric fractions of the investigated chiral PCBs could be determined free from interferences. However, limitations on the number of target compounds that can be transferred to the second column in a single run and, therefore, the time consumption, have led to the evaluation of GC x GC as an alternative for this type of analysis. With GC x GC, two column set-ups were tested, both having a chiral column as first-dimension column, and two different polar stationary phase columns in the second dimension. On using both column combinations, congeners 84, 91, 95, 132, 135, 136, 149, 174, and 176 could be determined free from coelutions with other PCBs. Results on the application of heart-cut MDGC to food samples such as milk and cheese are given, as well as the first results on the application of GC x GC to this type of samples.

“…According to Munoz-Olivas et al (2001), Jalbani et al (2007) heavy metals can be classified as potentially toxic (aluminium, arsenic, cadmium, etc.,) and essential (copper, iron, zinc, etc.). Humans are exposed to heavy metals in many different ways such as; by ingestion of contaminated water and food, and by inhalation of air pollutants or contaminated soil particles (Bordajandi et al, 2004). Long-term exposures to toxic elements can be very harmful even at low concentration but the intake of too much of essential metals can also cause produce toxic effects (Celik and Oehlenschlager, 2007).…”

Identification and Quantification of Heavy Metals Concentrations in <i>Pistacia</i>

The levels of heavy metals are very important in pistachio nuts, because the edible nuts have an important and increasing role in human nutrition. Pistachio is one of the native nuts of Iran which contains high genetic resources, but there is insufficient information regarding nutritional properties and other elements like heavy metals. The objective of the present study was to investigate and compare heavy metals contents in the kernels of various pistachio samples including: 'Daneshmandi' , 'Sephid' , 'Garmeh' , 'Momtaz' , ' Ahmad Aghaei' , 'Badami Zarand' , Pistacia atlantica Desf. ('Baneh'), Pistacia vera 'Sarakhs' and chance seedling as 'Non-grafted 1' , 'Non-grafted 2' and 'Non-grafted 3' . Inductively coupled plasma emission spectrophotometer (ICP) was used for the determination of aluminium, chromium, nickel, copper, strontium, arsenic, cadmium and cobalt concentrations in pistachio kernels. This study showed that there were significant differences among the samples in all measured heavy metals except the arsenic, cadmium and cobalt. The content of aluminium varied from 3.22 to 9.59 (mg kg -1 of dry matter) and chromium concentration from 0.60 to 1.86 (mg kg -1 of dry matter). The nickel content of examined pistachio samples was found between 0.43 and 3.63 (mg kg -1 of dry matter) and copper ranged from 3.20 to 12.33 (mg kg -1 of dry matter). The strontium content was observed between 4.96 and 24.93 (mg kg -1 of dry matter). The contents of arsenic, cadmium and cobalt not reported, because their amounts were lower than the detection limit of the applied measuring method (ICP). These data demonstrated that the concentrations of heavy metals in pistachios varied by cultivar.
