概括

农业再利用资源,如经过处理的废水和生物固体,但这引入了令人担忧的污染物. 需要采用整体的,跨学科的方法来评估风险,并确保循环经济的安全再利用.

科学领域:

环境科学环境科学
农业科学农业科学
毒理学毒理学毒理学

背景情况:

农业越来越多地重复使用资源,如处理的废水和生物固体.
这种重复使用将新兴关注的污染物 (CEC) 引入农业系统.
CEC包括农药,PFAS,纳米材料,微塑料,抗生素耐药基因和细菌.

研究的目的:

提供关于农业重复使用中CECs风险的整体视角.
突出目前以纪律和化学品类为中心的风险评估的局限性.
解决废水和生物固体安全和可持续再利用的监管挑战.

主要方法:

对农业系统中 CEC 的现有研究进行了审查.
化学,微生物学和环境科学知识的跨学科综合.
对污染物相互作用和环境因素的分析.

主要成果:

CEC 在农业系统中广泛存在,并且可以进入食物网.
目前的风险评估是孤立的,无法考虑污染物混合物和相互作用.
这限制了对生态系统和人类健康风险的准确评估.

结论:

多学科的方法对于理解农业资源再利用的复杂风险至关重要.
处理污染物混合物和相互作用对于有效的风险管理至关重要.
这种综合方法支持一个安全和可持续的卫生-农业循环经济.

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...
