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.
EPA MCLG Level
1000 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:
