概括
双动物中的和多基物质 (PFAS) 可以超过人类查水平,但暴露率低于通过鱼类. 双动物中的PFAS生物积累取决于链条长度,影响风险评估.
科学领域:
- 环境化学环境化学
- 生态毒理学 生态毒理学
- 食品安全 食品安全
背景情况:
- 和多基基物质 (PFAS) 是持久的环境污染物.
- 了解双组织中的PFAS对于评估人类和野生动物暴露路径至关重要.
研究的目的:
- 为了评估PFAS在受影响地点的双动物中的存在和生物积累.
- 为了比较双体消费作为PFAS暴露途径与鱼类消费.
主要方法:
- 从AFFF影响的地点的双组织中分析PFAS度.
- 关于PFAS生物积累在双动物中的实验室研究的综述.
- 通过双动物和鱼类消费预测的人类和野生动物饮食暴露的比较.
主要成果:
- 在一些地点,双动物中的PFOS度超过了人类查水平.

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.

The Periodic Table and Organismal Elements
22.2K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
