Abstract

ABSTRACT The objectives of this study were to assess concentrations of three groups of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in 44 fish oil-based food supplements, to estimate their daily intake by consumers and, to evaluate the compliance of the oil samples with the oil origin declarations (cod liver oil or fish oil). The concentrations of ∑PCBs (7 congeners), OCPs (19 compounds, represented mainly by ∑DDTs), ∑PBDEs (10 congeners), and ∑PAHs (16 compounds) found in samples ranged between 0.15–55.7 µg kg−1, 0.93–72.8 µg kg−1, 0.28–27.5 µg kg−1, and 0.32–51.9 µg kg−1, respectively. Besides, the authenticity of the oils was assessed based on the fingerprints obtained by DART–HRMS, an ambient mass spectrometry technique. Four samples declared as fish oil were probably prepared from cod liver oil, which is much cheaper. Furthermore, these samples contained elevated concentrations of halogenated POPs when compared to supplements produced from fish oil.

捷克市场鱼油食品补充剂中的持久性有机污染物和多环芳烃。

本研究的目的是评估44种鱼油为基础的食品补充剂中三组持久性有机污染物(POPs)和多环芳烃(PAHs)的浓度，估计消费者的每日摄入量，并评估油样品是否符合油来源声明(鱼肝油或鱼油)。样品中∑PCBs(7个同族化合物)、OCPs(19种化合物，主要为∑DDTs)、∑PBDEs(10种同族化合物)和∑PAHs(16种化合物)的浓度分别在0.15 ~ 55.7µg kg-1、0.93 ~ 72.8µg kg-1、0.28 ~ 27.5µg kg-1和0.32 ~ 51.9µg kg-1之间。此外，利用DART-HRMS环境质谱技术获得的指纹图谱对油的真伪进行了鉴定。4个被宣称为鱼油的样品可能是由便宜得多的鱼肝油制成的。此外，与鱼油生产的补充剂相比，这些样品含有更高浓度的卤化持久性有机污染物。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
