- 环境科学
- 生态毒理学
- 石化技术
背景情况:
- 菌繁殖和相关毒素对水生生态系统和人类健康构成风险.
- 是调节淡水湖生长的关键营养物质.
- 之前的模型预测在限制下毒素度增加.
研究的目的:
- 评估拟议的限制与毒素度增加相关的机制的有效性.
- 重新评估减少含量的影响 埃里湖的毒素水平.
主要方法:
- 在预测模型中引用的分子,生理和生态机制的批判性审查.
- 模型假设与现有的科学文献和经验数据进行比较.
主要成果:
- 在限制下增加毒素的预测的几个机制缺乏强有力的经验支持.
- 有关蓝菌对营养可用性的反应的关键假设存在矛盾的证据.

The Phosphorus Cycle
38.5K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Factors Affecting Solubility
33.8K
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:

Bioremediation
19.8K
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.
