概括

对性和多性物质 (PFAS) 的研究有限,对环境命运,生态毒性和陆地影响存在重大知识差距. 为了准确评估这些持久化学品的环境风险,需要进行更全面的研究.

科学领域:

环境化学环境化学
生态毒理学生态毒理学
风险评估风险评估

背景情况:

和多化物质 (PFAS) 是广泛存在的,持久的工业化学品,有成千上万种变体.
目前的PFAS环境研究显示出显著的偏差,重点关注少量的化合物,特定的环境组件和有限的生物体.

研究的目的:

确定知识缺口和研究需求,以对PFAS进行全面的环境风险评估.
突出目前PFAS环境研究的发展.

主要方法:

系统审查关于PFAS环境命运,生物积累和生态毒性的开放文献和数据库.
对有关PFAS化合物,环境组件和研究生物体的研究偏差的分析.

主要成果:

关于PFAS环境命运的知识不到1%的已知化合物,土壤和悬浮颗粒被研究不足.
生物积累和食物网转移研究仅限于少数PFAS,主要是在鱼类等水生生物中.
生态毒性数据稀缺,偏向水生生物;缺乏陆地,慢性和多代研究.

结论:

迫切需要研究研究不足的PFAS,陆地生态毒性和长期影响 (慢性,多代).
开发预测模型,将PFAS化学结构和特性与环境命运,生物积累和毒性联系起来,至关重要.
解决这些缺陷对于对PFAS进行全面的环境风险评估至关重要.

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...
