“…PAHs are a diverse family of more than 100 lipophilic organic contaminants composed of two or more fused aromatic rings [3]. These compounds are mostly formed in incomplete combustion of organic matter as a consequence of a series of natural and anthropogenic processes [4]. Due to their lipophilic nature, PAHs are accumulated in oils and fats that are a significant dietary source [5].…”

In a field experiment, the transfer of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from contaminated soil to maize (Zea mays L.), sunflower (Helianthus annuus), poplar (Populus nigra × P. maximowiczii) and willow (Salix × smithiana) and the distribution of PCB congeners in maize and sunflower was investigated. The former waste incinerator in Hradec Králové (Czech Republic) was chosen for the experiment. Results of plot screening showed heterogenous contamination by PCBs and PAHs. PCB soil contamination was evidently caused by Delor 106 or Aroclor 1260 stocking and PAH contamination by chemicals containing fluoranthene, benzo/b/fluoranthene, phenanthrene and pyrene. Tested plants were planted on a contaminated field site, in soil contaminated with 1530 µg/kg of total PCBs and 0.138 and 3.42 mg/kg of total PAHs. The results show that maize and sunflower roots accumulated the most PCBs from soil. These plants accumulated hexa- and heptachlorobiphenyl congeners more than tri-, tetra-, and pentachlorobiphenyl congeners. Total concentrations of PAHs in tested plants ranged from 0.096 to 1.34 mg/kg. The highest phenanthrene concentration was found in aboveground biomass of sunflower and the highest concentration of pyrene, in maize roots.

“…La préparation de l'échantillon fait intervenir une extraction liquide-liquide suivie d'une purification sur une colonne de silice (Moret et Conte, 2002), une colonne de silice puis une colonne de silice greffée aminopropyle (Moreda et al, 2004), une colonne de chromatographie d'exclusion stérique (Fiume et al, 2002), ou une colonne de chromatographie basée sur un complexe donneur-accepteur (Van Stijn et al, 1996). L'analyse de l'échantillon purifié est le plus souvent réalisée par HPLC-fluorescence.…”

The research of contaminants is part of multiple controls conducted by fat and oil industry to verify the conformity of products placed on the market in relation to regulations as for instance the commission regulation EC n o 1881/2006 setting maximum levels for some contaminants in food as lead, some mycotoxins, dioxins, polychlorobiphenyls, benzo [a]pyrene. In the absence of regulation, the detection of contaminants must be addressed in partnership with authorities according to the toxicity of molecules. The controls are not confined to environmental contaminants. They also include compounds that can be formed during the production process of vegetable oils such as esters of 3-monochloropropanediol. This article focuses on recent research analytical development more particularly on those related to polycyclic aromatic hydrocarbons, mineral oils, phthalates and esters of 3-monochloropropanediol.

“…Différents protocoles publiés récemment portent sur la détermination des congénères de HAP dans les corps gras. La préparation de l'échantillon fait intervenir une extraction liquide/liquide suivie d'une purification sur : i) une colonne de silice [10], ii) une colonne de silice puis une colonne de silice greffée amino-propyle [11], iii) une colonne de chromatographie d'exclusion stérique [12], iv) une colonne de chromatographie basée sur un complexe donneur-accepteur [13]. En 1999, l'ITERG a développé une méthode de détermination de 12 HAP, dont 6 composés légers et 6 lourds.…”

Résumé : La présence des hydrocarbures aromatiques polycycliques (HAP) dans les huiles végétales peut provenir de différentes sources, mais généralement les huiles contaminées sont issues de matières premières nécessitant d'être séchées telles que les pépins de raisin, le coprah ou les grignons d'olive. Actuellement, il n'y a pas de réglementation européenne limitant la teneur en HAP dans les produits alimentaires mais un Code de Bonnes Pratiques a été établi par FEDIOL Summary :The presence of polycyclic aromatic hydrocarbons (PAHs) in vegetable oils may be due to different sources, but generally the contaminated oils come from raw material that need to be dried, such as grape seeds, coconut, or pomace olive. At the present time, there is no European regulation for PAHs but an Industrial Code of Practice was provided by FEDIOL which is the European Association of Oilseed Crushers. PAHs determination in fatty material is difficult mainly due to low level of individual PAHs to be quantified and to the complexity of the extraction and purification steps. The only test method already standardised (NF EN ISO 15302) deals with the determination of benzo [ a]pyrene. A committee draft test method provided by ITERG is under evaluation within ISO\\TC34\\SC11 for determination of 12 PAHs. Limits of quantification are respectively 1 µg\\kg for indeno [ 1,2,3-cd]pyrene, 0.3 µg\\kg for fluoranthene and benzo [ g,h,i]perylene, 0,2 µg\\kg for 9 other compounds analysed. For the last 4 years, ITERG's work on PAHs was focused on improvement and standardisation of the analytic procedure (ISO\\CD 15753), estimation of level of contamination of French vegetable oils (mainly grapeseed oils) and the evaluation of refining effect on the PAHs contamination. Each part of this work is summarised in this paper.Article disponible sur le site http://www.ocl-journal.org ou http://dx
