EFSA journal. European Food Safety Authority
|December 10, 2024
概括
海鲜中的贝 (AsB) 和糖醇糖 (AsSugOH) 在当前的饮食暴露水平下不构成健康风险. 对食品中的其他有机化合物需要进一步研究.
科学领域:
- 食品安全和毒理学
- 环境化学环境化学
- 污染物的风险评估.
背景情况:
- 有机物种,包括贝 (AsB),糖和脂,在海洋食品中普遍存在.
- 欧洲委员会要求进行风险评估,以评估这些化合物的安全性.
研究的目的:
- 对食品中复杂的有机物种进行风险评估,重点关注AsB和糖甲糖 (AsSugOH).
- 确定当前饮食中这些化合物的暴露水平是否会引起健康问题.
主要方法:
- 对AsB的毒性数据评估,包括重复剂量毒性和基因毒性测定.
- 用小鼠研究中的BMDL10值推导AsSugOH的参考点 (RP).
- 对AsB和AsSugOH的暴露评估基于相关人口群体的95百分位数估计.
- 计算暴露率 (MOE) 以评估健康风险.
主要成果:
- 由于毒性数据不足,无法得出AsB的参考点;然而,可用的数据没有显示任何不良影响或基因毒性.
- 据估计,AsB暴露的最高值为每天12.5μg As/kg bw,没有发现健康问题.
- 对于AsSugOH,一个参考点是每天0.85 mg As/kg bw.
- 最高估计的AsSugOH暴露量为每天0.71μg As/kg bw,导致MOE>1000,表明没有健康问题.
- 通过饮食接触AsB和AsSugOH被认为不太可能引起健康问题.
结论:
- 目前食品中AsB和AsSugOH的饮食暴露水平并不构成健康问题.
- 由于数据有限,无法对其他糖得出进一步的结论.
- 由于数据不足,无法对脂质进行风险表征.

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.

Toxic Reactions: Overview

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
