How are reactive nitrogen species classified in terms of environmental impact?

Reactive nitrogen species are classified as pollutants leading to water quality issues due to their ability to significantly impact aquatic ecosystems and overall water quality. These species, which include forms like nitrate and ammonium, can contribute to problems such as eutrophication. Eutrophication occurs when excessive nutrients enter a body of water, promoting algal blooms that reduce oxygen availability and harm aquatic life. Additionally, reactive nitrogen can affect the pH levels in water bodies and disrupt the balance of ecosystems, leading to harmful consequences for fish and other organisms.

The classification of reactive nitrogen species as pollutants highlights their potential to degrade water quality, which is a crucial concern in environmental management and wastewater treatment practices. Effective monitoring and regulation of these compounds are necessary to protect water resources and maintain ecosystem health.
