概括

在84%的食品包装中普遍存在Per-和多醇基物质 (PFAS),其中 6:2基二 (6:2 diPAP) 是最常见的. 迁移研究表明潜在的饮食暴露,尽管水平仍低于安全限值.

科学领域:

环境化学环境化学
食品安全食品安全
分析化学分析化学

背景情况:

由于其耐油脂和耐水性质,Per-和多基物质 (PFAS) 在食品包装中被广泛使用.
有关PFAS从包装到食品的潜在迁移存在担忧,导致通过饮食暴露.
食品包装成分的地理差异可能会影响PFAS的流行率和水平.

研究的目的:

调查不同地理来源的食品包装中的各种PFAS的存在和量化水平.
评估总可氧化前体 (TOP) 测定对PFAS检测的影响.
评估PFAS迁移到食品模拟剂,并估计人类潜在的饮食暴露.

主要方法:

针对性液体染色学-并联质谱学 (LC-MS/MS) 和高分辨率质谱学 (HRMS) 用于PFAS分析.
样品在TOP测定前后进行提取和分析,以识别和量化PFAS.
使用食品仿真剂进行的迁移实验是对选定的样本进行的,随后进行每周摄入量计算.

主要成果:

在88个食品包装样本中,有84%含有可检测的PFAS,其中6:2基二 (6:2二PAP) 是最常见和最丰富的.
平均总PFAS (PFAS) 含量从前的28.3 ng/g显著增加到TOP试验后的381.9 ng/g.
观察到PFAS迁移到食品模拟剂中,估计每周摄入量低于欧洲食品安全局 (EFSA) 的可容忍每周摄入量 (TWI).

结论:

食品包装是PFAS暴露的重要来源,检测到各种PFAS化合物.
TOP测定对于包括前体在内的PFAS的全面评估至关重要.
虽然发生迁移,但研究的包装样本中估计的饮食暴露仍然低于既定的安全值.

关键词:

暴露暴露暴露移民移民移民在PFAS中,有很多方法.对嫌疑人进行查.在TOP测试中进行测试.

Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Microbial Bioremediation of Plastics

Microbial Bioremediation of Plastics

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...
