概括

聚二乙烯 (PBDE) 污染动物料,其中鱼油和鱼粉含量最高. 然而,自2017年以来,鱼粉中的PBDE度显著下降,这表明有效的环境立法.

科学领域:

环境化学环境化学
食品安全食品安全
毒理学毒理学毒理学

背景情况:

聚二乙烯 (PBDE) 是一种在各种环境基质中发现的持久性有机污染物.
人类接触PBDE通常是通过食用受污染的食物,特别是动物来源的食物而发生.
料质量是影响动物来源食品安全的关键因素.

研究的目的:

评估各种料和料原料中十种PBDE同源的污染水平.
为了确定哪些料类别受到PBDE污染的影响最大.
评估当前立法在减少动物料中PBDE含量的有效性.

主要方法:

分析了8个类别的207个料样本,使用气色谱-高分辨率质谱法 (GC-HRMS).
对十种特定的PBDE同源的量化 (BDE-28,47,49,99,100,138,153,154,183和209) 的研究.
2017年至2021年鱼粉样本中PBDE度的时间趋势分析.

主要成果:

在所有分析的料样本中,73%检测到PBDE.
鱼油,动物脂肪和鱼类料显示普遍受到污染,而80%的植物性料是无PBDE的.
鱼油的PBDE中位数度最高 (2260 ng/kg),其次是鱼粉 (530 ng/kg). BDE-209是最经常检测到的同源 (56%).
2017年至2021年间,在鱼粉中观察到PBDE总量显著下降 (PBDE10减少63%,p=0.077;PBDE9减少50%,p=0.008).

结论:

动物料,特别是鱼油和鱼粉,可以成为PBDE污染的重要来源.
在鱼粉中观察到的PBDE含量下降表明,旨在减少这些污染物的国际法规是有效的.
持续监测动物料中的PBDE对于确保食品链安全至关重要.

关键词:

Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene

Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...
