概括

像银化物 (HHCB) 和化物 (AHTN) 这样的合成,在全球范围内分布在环境中. 虽然一般来说风险很低,但废水厂附近的高度表明局部环境问题.

科学领域:

环境化学环境化学
生态毒理学生态毒理学
分析化学分析化学

背景情况:

合成香在消费品中被广泛使用,作为天然香的替代品.
增加产量引发了人们对它们对环境和人类健康的影响的担忧.
之前的审查集中在分析方法上,缺乏系统的全球分布分析.

研究的目的:

系统地审查环保媒体中合成的全球发生和分布.
探索合成的环境命运,持久性,生物积累和毒性 (PBT).
评估与合成香污染相关的生态风险.

主要方法:

对报告在环境样本 (水,沉积物,生物群) 中合成的发生研究的综合文献综述.
基于检测频率和度的全球分布模式分析.
评估持久性,生物积累和毒性数据,包括风险系数 (RQ) 计算.

主要成果:

银化物 (HHCB) 和化物 (AHTN) 是全球检测最频繁的合成,在西方国家度更高.
多环和酸米斯克表现出持久性和生物积累潜力.
大多数水生物种和沉积物种的风险系数 (RQs) 通常较低 (<0.1),但在废水处理厂 (STPs) 附近观察到高风险 (RQs>1).

结论:

合成香,特别是HHCB和AHTN,是无处不在的环境污染物,具有明显的全球分布模式.
虽然整体生态风险较低,但在污染源附近的局部热点需要注意.
需要进一步研究宏环和环,长期毒理效应以及潜在的协同影响.

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...
