註釋This document presents a guidance framework for the management of phosphorus in freshwater systems. The introduction reviews the development & validation of this framework. Chapter 2 presents a review of the scientific literature on phosphorus in the aquatic environment, including properties, sources, fate, sediment interactions, parameters affecting phosphorus availability, trophic status, & effects on organisms. Chapter 3 examines a number of approaches used by other jurisdictions for setting phosphorus guidelines. Chapter 4 outlines the proposed framework-based approach for phosphorus management in which water bodies are marked for further assessment by comparing their trophic status to predefined ranges of phosphorus concentration. Chapter 5 summarizes some of the recommended assessment options currently use in Canada & other jurisdictions. Chapter 6 reviews management options that can be considered once the phosphorus concentrations have been assessed & compared to original goals for the water body. The final two chapters present case studies of implementation of this framework at Lake Simcoe in Ontario and at Kodiak Lake, Northwest Territories.
