Abstract

This study systematically analyzed 17 per-and polyfluoroalkyl substances (PFASs) in seafood samples collected from Taizhou, southeast China, and assessed the health risks to local residents. Results revealed widespread PFAS contamination, with overall detection frequencies ranging from 51.3 % (bivalve) to 72.7 % (shrimp). Perfluorooctane sulfonic acid (PFOS) and perfluorotridecanoic acid (PFTrDA) exhibited the highest detection frequencies at 38.2 % and 41.2 %, respectively. Marine fish, particularly mackerel, hairtail, and hatchetfish, had high PFOS levels (up to 11.4 µg/kg ww), while shrimp displayed high PFTrDA concentrations (0.85 µg/kg ww) and perfluoroundecanoic acid (PFUnDA, 0.87 µg/kg ww). Perfluorododecanoic acid (PFDoDA) and perfluorodecanoic acid (PFDA) exhibited a strong positive correlation (r = 0.89, p < 0.01). Dietary exposure assessment revealed that the total estimated daily intake (EDI) of PFOA, PFOS, perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS) based on median residual levels was 1.62 ng/kg/day for males and 1.91 ng/kg/day for females. For frequent seafood consumers, there is potential long-term health risks. This study highlights the need for enhanced monitoring of PFASs in seafood and targeted dietary guidance to mitigate human exposure in coastal regions.

中国东南海产品中全氟辛烷磺酸残留分析及膳食暴露风险评估

本研究系统分析了台州海产品样品中的17种全氟烷基和多氟烷基物质（PFASs），并对当地居民的健康风险进行了评估。结果显示广泛存在PFAS污染，总体检测频率从51.3 %（双壳类）到72.7 %（虾类）不等。全氟辛烷磺酸（PFOS）和全氟三烷酸（PFTrDA）的检测频率最高，分别为38.2 %和41.2 %。海洋鱼类，特别是鲭鱼、带尾鱼和戟鱼的全氟辛烷磺酸含量很高（高达11.4 µg/kg ww），而对虾的PFTrDA浓度很高（0.85 µg/kg ww），全氟癸酸浓度很高（PFUnDA, 0.87 µg/kg ww）。全氟十二烷酸（PFDoDA）与全氟十二烷酸（PFDA）呈强正相关（r = 0.89,p <； 0.01）。膳食暴露评估显示，基于中位残留水平的PFOA、PFOS、全氟壬烷酸（PFNA）和全氟己烷磺酸（PFHxS）的估计总日摄入量（EDI）男性为1.62 ng/kg/天，女性为1.91 ng/kg/天。对于经常食用海鲜的人来说，存在潜在的长期健康风险。这项研究强调需要加强对海产品中全氟辛酸的监测和有针对性的饮食指导，以减轻沿海地区人类的暴露。

期刊介绍： The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects. The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
