概括

一种新的藻类-鱼处理方法未能从废水中去除危险的精神药物. 这种以自然为基础的方法增加了环境风险,因为某些药物的积累,证明不适合有效的污染物去除.

科学领域:

环境科学环境科学
生态毒理学生态毒理学
环境化学环境化学

背景情况:

精神药物是水生环境中新兴的危险污染物.
传统的废水处理厂 (WWTP) 不能充分去除这些污染物.
需要三级治疗方法来减轻精神药物产生的风险.

研究的目的:

评估一种以自然为基础的三级治疗方法,使用藻类-贝的热带级联来消除精神药物.
为了评估30种精神药品在WWTP废水中的去除效率.
将删除数据与指导性风险评估联系起来.

主要方法:

设计了一种藻类-鱼的热带级联,鱼暴露在废水中11天,然后鱼暴露在废水中3天.
计算了12种定量化精神药物的去除效率,相对于对照样本.
进行了风险评估,以评估处理对环境的影响.

主要成果:

在12种检测到的精神药物中,有11种在所有治疗中都存在.
藻类,而不是贝,主要推动了积极的 (例如,citalopram) 和消极的 (例如,carbamazepine) 移除.
由于藻类生长的pH值增加,低pKa化合物表现出负去除;易布洛芬没有被去除.

结论:

藻类-鱼级联并没有有效地去除精神药物,并增加了环境风险.
负去除高度化合物,如卡巴马西平的整体风险升高.
这种以自然为基础的治疗不适合从WWTP废水中去除精神药物.

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.

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

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...

Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:
