邻苯二甲酸酯是有机亲脂化合物，主要用作增塑剂，以增加塑料聚合物的柔韧性。邻苯二甲酸盐在印刷油墨和漆中的应用。人类接触邻苯二甲酸盐主要是通过食物摄入，可引起不良的健康影响。在这项研究中，调查了在比利时市场上销售的400种食品中存在的八种邻苯二甲酸酯化合物——邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸二异丁酯（DiBP）、邻苯二甲酸二丁酯（DnBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二环己酯（DCHP）和邻苯二甲酸二辛酯（DnOP）。为此，开发并验证了适用于四种不同基质的提取技术，即高脂肪食品、低脂肪食品、水基饮料和包装材料。仪器分析采用气相色谱-低分辨率电子冲击电离质谱联用（GC-EI-MS）。在不同组中观察到的邻苯二甲酸盐浓度差异很大。DEHP几乎在每一组中浓度都最高。邻苯二甲酸酯化合物中DEHP含量最高，其次为DiBP、DnBP和BBP。这项调查是PHTAL项目的一部分，这是第一个讨论比利时食品市场上邻苯二甲酸盐污染的项目。(C) 2012 Elsevier Ltd.版权所有。
Phthalates are organic lipophilic compounds that are principally used as plasticiser to increase the flexibility of plastic polymers. Other applications are a.o. the use of phthalates in printing inks and lacquers. Human exposure to phthalates mainly occurs via food ingestion and can induce adverse health effects. In this study, the presence of eight phthalate compounds - dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), benzylbutyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), dicyclohexyl phthalate (DCHP) and di-n-octyl phthalate (DnOP) - was investigated in 400 food products, divided over eleven groups, and packages sold on the Belgian market. For this purpose, suitable extraction techniques were developed and validated for four different matrices, namely high-fat foods, low-fat food products, aqueous-based beverages and packaging materials. The instrumental analysis was performed by means of gas chromatography-low resolution-mass spectrometry with electron impact ionisation (GC-EI-MS). A wide variety of phthalate concentrations was observed in the different groups. DEHP was found in the highest concentration in almost every group. Moreover, DEHP was the most abundant phthalate compound, followed by DiBP, DnBP and BBP. This survey is part of the PHTAL project, which is the first project that discusses phthalate contamination on the Belgian food market. (C) 2012 Elsevier Ltd. All rights reserved.
