Quizplus · Accepted Answer

Nitrate is a powerful oxidizer and can increase the movement of toxic arsenic. Nitrate in lakes can promote the release of arsenic from sediment, making it more available to plants and animals. Nitrate does not cause acidity but can contribute to eutrophication, which can lead to low oxygen levels in the water and harm aquatic life.
