“…As far as we know, this is the first time this matrix has been studied with regard to PAHs after a forest fire. In a similar study, Costopoulou et al (8) looked at the presence of these kinds of pollutants in olive and olive oil samples from areas affected by forest fires in Greece. For the same PAHs that we studied, they reported levels that were considerably lower than those found in samples of extra virgin olive oil that came from olive oil mills or from the retail market (most of the compounds were below the LODs, and BaP levels were always below 1 pg/kg).…”

A survey of honey samples from different geographical and botanical origins, including some samples collected from a fire-affected area in Spain, was conducted to assess their content of heavy metals and polycyclic aromatic hydrocarbons (PAHs). The levels of the determined toxic elements (Pb, Cd, As, and Sn) were low and were in the range of those reported by other studies. In our work the total amount of heavy metals and Pb was higher in dark honeys than in pale honeys. In the collected samples, no detectable levels of the 15 PAHs studied were found. The obtained data served to assess the levels of heavy metals and PAHs in honey samples from different geographical and environmental origins and to contribute to the scarce data about pollutant content of this matrix. In light of these results, the analyzed samples do not pose any serious concern to human health, and the data obtained in this study could serve to contribute to the establishment of specific maximum limits for honey.

“…Indeed, it is well known that dioxins essentially bioaccumulate in animal fats because of their high lipophilicity [ 6 ]. Accordingly, dioxin and dioxin-like compounds were often detected in rape and olive oils [ 32 , 33 ]. Moreover, the sorption of hydrophobic organic compounds (HOC) by lipid bodies of rapeseeds as a HOC-removal strategy is well documented [ 34 , 35 ].…”

Differential tissue accumulation of 2,3,7,8-Tetrachlorinated dibenzo-p-dioxin in Arabidopsis thaliana affects plant chronology, lipid metabolism and seed yield

BackgroundDioxins are one of the most toxic groups of persistent organic pollutants. Their biotransmission through the food chain constitutes a potential risk for human health. Plants as principal actors in the food chain can play a determinant role in removing dioxins from the environment. Due to the lack of data on dioxin/plant research, this study sets out to determine few responsive reactions adopted by Arabidopsis plant towards 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic congener of dioxins.ResultsUsing a high resolution gas chromatography/mass spectrometry, we demonstrated that Arabidopsis plant uptakes TCDD by the roots and accumulates it in the vegetative parts in a tissue-specific manner. TCDD mainly accumulated in rosette leaves and mature seeds and less in stem, flowers and immature siliques. Moreover, we observed that plants exposed to high doses of TCDD exhibited a delay in flowering and yielded fewer seeds of a reduced oil content with a low vitality. A particular focus on the plant fatty acid metabolism showed that TCDD caused a significant reduction in C18-unsaturated fatty acid level in plant tissues. Simultaneously, TCDD induced the expression of 9-LOX and 13-LOX genes and the formation of their corresponding hydroperoxides, 9- and 13-HPOD as well as 9- or 13-HPOT, derived from linoleic and linolenic acids, respectively.ConclusionsThe current work highlights a side of toxicological effects resulting in the administration of 2,3,7,8-TCDD on the Arabidopsis plant. Similarly to animals, it seems that plants may accumulate TCDD in their lipids by involving few of the FA-metabolizing enzymes for sculpting a specific oxylipins “signature” typified to plant TCDD-tolerance. Together, our results uncover novel responses of Arabidopsis to dioxin, possibly emerging to overcome its toxicity.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-015-0583-5) contains supplementary material, which is available to authorized users.

“…Regarding the cleanup process, ISO 15753:2016 recommends two steps: a first application of a C18 column and a subsequent SPE based on a Florisil cartridge. This procedure has been effectively reproduced by some authors (Costopoulou et al, 2010;Ergönül & Sánchez, 2013;Teixeira et al, 2007;Yousefi et al, 2018). In other cases, the single use of C18 cartridges (without any further SPE) for the purification has been reported, mainly following two diverse strategies.…”

“…The optimum separation conditions usually imply a solvent gradient with ACN and water. Gradients normally start with a 40% to 50% ACN, in most cases (Barranco et al, 2003;Costopoulou et al, 2010;Gharbi et al, 2017;Martinez-López et al, 2005;Payanan et al, 2013;Shi et al, 2015Shi et al, , 2018Stenerson et al, 2015;Taghvaee et al, 2016;Teixeira et al, 2007;Yousefi et al, 2018;Zhao et al, 2013); then this concentration is linearly risen to 89% to 100% in an approximate time of 45 min, as so suggests ISO 15753:2016. Some reports have indicated the use of gradients with a higher proportion of ACN (70% to 85%) at the beginning of the run (Alves da Silva et al, 2017;Camargo et al, 2011;Ergönül & Sánchez, 2013;Ji et al, 2017;Molle et al, 2017;Moreda et al, 2004;Purcaro et al, 2008;Rodríguez-Acuña et al, 2008a;Tfouni et al, 2014).…”

Polycyclic aromatic hydrocarbons (PAHs) are food contaminants whose presence in foodstuffs is especially alarming due to their carcinogenic character. These substances are highly lipophilic and thus, unsafe levels of these compounds have been found in edible fats and oils. Efficient methodologies to determine such molecules in lipidic matrixes are therefore essential. In this review, a detailed description of the analytical methods for the determination of PAHs in vegetable oils from the last 15 years has been provided. Particular emphasis has been placed on innovative sample treatments, which facilitate and shorten the pretreatment of the oils. Finally, results from recent investigations have been reviewed and studied in depth, in order to elucidate which PAHs are most commonly found in vegetable oils.
