| 520 | |a"Phosphorus is a plant nutrient that is essential in freshwater systems. However, when phosphorus levels are too high, or too low, they can have harmful impacts on the health of a lake. High phosphorus levels in Lake Erie are leading to degraded water quality, algal blooms and zones of low oxygen which negatively impact aquatic life. In the absence of human development, natural background levels of phosphorus are relatively low. This indicator provides information about the amount of phosphorus reaching Lake Erie, known as phosphorus loading, mainly due to human activity"--Page 5. |
