概括

森林火灾后的森林再生包括微量元素监测. 潜在有毒元素 (PTEs) 的树种生物积累模式各不相同,为污染的生态系统中的植物修复提供了见解.

科学领域:

环境科学环境科学
森林生态森林生态
生物地质化学生物地质化学

背景情况:

火引起的有机物矿化改变了微量元素的生物地化学循环.
森林火灾后的森林生态系统再生需要监测复林策略的微量元素.
人为压力和工业污染对森林生态系统产生影响.

研究的目的:

分析潜在有毒元素 (PTE) 土壤度和火灾后树木生物质中的生物积累.
评估不同树种的微量元素植物稳定和生物积累模式.
评估树种选择对火灾后环境中的生物地球化学循环的影响.

主要方法:

对土壤和树木生物质 (Pinus sylvestris,Betula pendula,Alnus glutinosa) 进行PTEs (Al,Cd,Cr,Pb,Cu,Mn,Ni,Zn) 的分析.
在地下和地表生物质中测量生物积累因子和转移因子 (TF).
在火灾后的生态系统中,在不同树种中比较PTE积累模式.

主要成果:

在火灾后的现场,没有发现经过测试的PTE的直接威胁.
树种表现出不同的PTE生物积累策略 (例如,根与树叶中的Al,不同的Cd,Cr,Cu,Ni,Pb,Zn度).
特定物种的PTE生物积累模式与火灾干扰无关,这表明有污染土壤的可能性.

结论:

不同的树种具有独特的PTE植物稳定和生物积累模式.
这些取决于物种的模式可以为工业影响地区的复林和植物修复策略提供信息.
了解生物积累对于设计污染森林生态系统的有效修复处理至关重要.

Bioremediation

Bioremediation

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.

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...

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
