Nitrite (as N)
Nitrite is a chemical compound with the formula NO2. It is a nitrogen oxoanion and is often found in water as a result of the breakdown of organic matter or from agricultural runoff. Nitrite can be harmful in high concentrations and is often monitored in drinking water.
Health Guideline Level (HGL)
1 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Exposure to high levels of nitrite can lead to methemoglobinemia, a condition that reduces the blood's ability to carry oxygen. Symptoms may include shortness of breath, fatigue, and cyanosis (bluish discoloration of the skin). Long-term exposure may have other health implications, particularly for infants and pregnant women.
Affected Organs & Systems:
Common Sources
- Agricultural runoff
- Industrial discharge
- Natural deposits
