概括
海洋塑料污染很普遍,在全球范围内发现了微塑料 (MP). 这一元分析揭示了高MP密度,特别是在沉积物中,可能会损害海洋生物和影响生物过程.
科学领域:
- 海洋生物学 海洋生物学
- 环境科学 环境科学
- 生态毒理学 生态毒理学
背景情况:
- 海洋塑料垃圾是一个日益严重的全球问题,在所有海洋环境中都检测到了微塑料 (MP).
- 了解MP分布和生态影响对于有效的环境管理至关重要.
研究的目的:
- 量化微塑料 (MP) 在各种海洋息地中的全球丰度和分布.
- 评估MP污染对海洋动物的生态影响.
主要方法:
- 一项对334项研究的元分析,系统地审查了全球水柱,潮间和海底息地中的MP密度.
- 数据提取和统计分析MP的丰富性,考虑到各种息地类型和颗粒大小.
主要成果:
- 微塑料无处不在,平均全球密度为37,921颗/m2,在沉积物中明显高于水柱.
- 亚洲,热带地区和红树林的MP密度最高,但在"蓝色碳"息地并没有持续升高.
- 为更小的粒子大小 (0.01毫米) 进行调整,估计的全球MP密度增加到57,953颗粒子/平方米,这表明海洋MP总负载超过15亿.
结论:
- 目前在采样地点的MP密度足够高,对海洋动物的生长和繁殖产生负面影响.

Bioremediation
22.0K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Environmental Applications of Microorganisms
912
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Types of Toxins
3.1K
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.

Primary Production
25.0K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
