概括

室内空气中的微塑料 (MPs) 用拉曼微光谱法量化. 手术口罩显著减少MP摄入量,但对于最小的可呼吸颗粒来说效果不佳.

科学领域:

环境科学环境科学
分析化学分析化学
公共卫生公共卫生

背景情况:

微塑料 (MP) 是无处不在的环境污染物.
空载MP对人类健康构成潜在风险,需要量化方法.
可呼吸部分 (<5微米) 尤其令人担忧.

研究的目的:

在不同的人类活动水平下量化室内空气中的MPs (>1μm).
为了评估手术口罩对空中MP的过效率.
估计人类从室内空气中吸收的MP和面罩的保护作用.

主要方法:

拉曼微光谱 (μRaman) 用于MP的识别和量化.
在各种室内环境 (会议室,车间,公寓) 中进行空中MP采样.
对 IIR 手术面罩的过效率测试.

主要成果:

室内空气中的MP度从58到684MP m-3.3不等.
外科面罩保留了85.4 ± 3.9%的总MP.
估计每天的MP摄入量从3415下降到283个MP与面罩使用.
面具效率下降到57.6%的1-5微米透气分数.

结论:

人类活动,位置特征影响室内空气中的MP水平.
手术口罩对空中的国会议员提供了显著的保护.
面罩的有效性在较小,可呼吸的微塑料颗粒下降.

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...
