In decision making processes today it is typically economic considerations that are the focus and that dictate what decisions are made; however, this approach neglects significant potential impacts these decisions can have, namely environmental impacts. One way to incorporate environmental considerations into current decision making processes is through monetary valuation. This work surveys environmental economics literature that quantifies the monetary valuation of nutrients and nutrient pollution, and applies monetary valuation of phosphorus to a case study of nutrient recovery in wastewater treatment. The literature review catalogues three different monetary valuation methods, economic consequences, mitigation and restoration, and willingness to pay, and highlights the different perspectives each of these methods addresses. Additionally, the case study demonstrates how monetary valuation can be applied in a realistic decision making scenario and highlights how variability in monetary valuation methods and results can affect decision making. From this literature and case study assessment a call can be made to establish more standardized methods for determining the monetary valuation of nutrients in an effort to promote and encourage the consideration of nutrient pollution issues in future decision making.

探索环境中磷的经济价值及其对资源回收决策的影响。

在当今的决策过程中，通常以经济考虑为重点，并决定做出何种决策；然而，这种方法忽略了这些决定可能产生的重大潜在影响，即环境影响。将环境因素纳入当前决策过程的一种方法是通过货币估值。这项工作调查了量化养分和养分污染的货币估值的环境经济学文献，并将磷的货币估值应用于废水处理中养分回收的案例研究。文献综述列出了三种不同的货币估值方法、经济后果、缓解和恢复以及支付意愿，并强调了每种方法所涉及的不同观点。此外，案例研究展示了如何将货币估值应用于现实的决策场景，并强调货币估值方法和结果的可变性如何影响决策。根据这些文献和案例研究评估，可以呼吁建立更标准化的方法来确定养分的货币估值，以促进和鼓励在未来决策中考虑养分污染问题。
