概括

建筑湿地有效地去除化物,种植系统和更长的保留时间显示出最佳结果. 在这些系统中,Auxin的修改进一步提高了化物去除率.

科学领域:

环境工程环境工程
水处理技术水处理技术
植物科学植物科学

背景情况:

水中的化物污染对健康构成重大风险.
建筑湿地 (CWs) 是一个有前途的基于自然的水资源整治解决方案.
了解植物-CW相互作用对于优化除化是至关重要的.

研究的目的:

评估建筑湿地的化物清除效果.
评估液压保留时间 (HRT),植物存在 (Eichhornia crassipes) 和auxin修改对化物去除的影响.
研究植物组织中的化物积累和相关的解剖变化.

主要方法:

九个水平地下流CW被运行在不同的HRTs (2,5,10天).
种植CW时种植了Eichhornia crassipes或没有种植,有或没有auxin修改.
测量了废水和植物组织中的化物水平;评估了植物解剖学.

主要成果:

种植的CW实现了>69%的化物去除,特别是在5天和10天的HRT.
素的修改提高了化物去除率,特别是在2天的CW中.
化物积聚在植物芽中,根部解剖学显示出诸如膜损失之类的改变.

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:

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
