概括

和多化基物质 (PFAS) 存在于与食品接触的材料中,如爆米花袋和披萨盒. 分析显示,饼杯中的PFAS含量很高,这表明了潜在的饮食暴露风险.

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:

和多化基物质 (PFAS) 在食品接触材料 (FCM) 中用于防水和防脂.
PFAS是化学稳定的,持久的,对人类健康和环境构成风险.
来自丹麦和西班牙市场的纸质FCM被分析为PFAS含量.

研究的目的:

调查PFAS在纸质FCM中的存在和度.
为了识别特定的PFAS化合物,包括 perfluoroalkyl carboxylic 酸 (PFCA), perfluoroalkyl 硫酸 (PFSA) 和多化端粒醇 (FTOH).
评估从FCM迁移到PFAS的潜在饮食暴露.

主要方法:

里埃变换红外光谱 (FTIR) 用于FCM的表征.
液体染色学-并联质谱学 (LC-MS/MS) 用于量化食品仿真剂中已知的PFAS.
液体染色学 - 轨道高分辨率质谱学 (LC-Orbitrap-HRMS) 用于非目标查PFAS.

主要成果:

在各种基于纸的FCM样本中检测到PFAS.
一个纤维素饼干杯显示了PFCA (~1.41μg kg−1食物) 和FTOH (~11.5μg kg−1食物) 的最高度.
非有针对性的选发现了20种额外的PFAS化合物,包括甲基酸和含乙烯的物质,其中5种被归类为置信级1和10种归类为置信级2.

结论:

该研究强调了纸质FCM中存在各种PFAS的存在.
量化PFAS只占有机体总量的很小一部分,这表明存在其他未确定的PFAS.
先进的分析技术对于全面了解食品接触材料中的PFAS污染及其相关风险至关重要.

Traumatic Brain Injury l: Introduction

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.
