尽管人们对多氯化萘和许多同系物表现出的二恶英类毒性越来越感兴趣，但仍然缺乏对其对二恶英类污染物混合物的贡献的全面评估。为了解决这一缺陷，本研究调查了最近从法国购买的食品中的多氯化萘污染情况，以及监管的多氯二苯并二恶英/呋喃 (PCDD/F) 和多氯联苯 (PCB) 的污染情况。多氯化萘普遍存在，其水平（Σ70 多氯化萘 = 2.5–150 pg g ^–1湿重）与其他国家报告的水平相似，在来自东北大西洋的鱼类和渔业产品中观察到最高浓度。它们的同类模式进一步表明多氯化萘的无意释放，而其他食品的排放则与历史多氯化萘分布相关。估计膳食暴露风险较低（Σ70 PCNs-EDI 为 60–360 pg kg ^–1 bw d ^–1 ，Σ24 PCNs-TEQ-EDI 为 8 × 10 ^–3 –2.2 × 10 ^–2 pg TEQ kg ^–1 bw d ^–1 )，其中牛奶和乳制品的贡献最大，其次是肉类和肉制品。最后，PCNs 对 PCNs+PCDD/Fs+PCBs 总浓度（0.9-50%，平均 9%）和毒性当量（0.2-24%，平均 5%）的贡献相当高，表明这些物质不是 PCNs+PCDD/Fs+PCBs 混合物中的次要成分。

Polychlorinated Naphthalenes in Foods from the French Market: Occurrence, Dietary Exposure, and Evaluation of Relative Contributions to Dioxin-like Contaminants

Despite the growing interest in PCNs and the dioxin-like toxicity exhibited by a number of congeners, a comprehensive assessment of their contribution to the cocktail of dioxin-like contaminants is still lacking. To address such a shortcoming, this study investigated the PCN contamination in foodstuffs recently acquired in France, together with that of the regulatory polychlorinated dibenzodioxins/furans (PCDD/Fs) and polychlorinated biphenyls (PCBs). PCNs were ubiquitous at levels (∑70 PCNs = 2.5–150 pg g^–1 wet weight) similar to those reported in other countries, with maximum concentrations observed in fish and fishery products from the North-East Atlantic Ocean. Their congener patterns further suggested unintentional releases of PCNs, while those of the other foodstuffs were correlated to the historical PCN profiles. Low risk from dietary exposure was estimated (∑70 PCNs-EDIs of 60–360 pg kg^–1 bw d^–1, ∑24 PCNs-TEQ-EDIs of 8 × 10^–3–2.2 × 10^–2 pg TEQ kg^–1 bw d^–1), with milk and dairy products being the highest contributors, followed by meat and meat products. Finally, the rather high contributions of PCNs to the total PCNs+PCDD/Fs+PCBs concentrations (0.9–50%, average of 9%) and the toxic equivalents (0.2–24%, average of 5%) show that these substances are not minor components of the PCNs+PCDD/Fs+PCBs cocktail.
