Health Effects of Nitrite Exposure

Blue baby syndrome

Can block oxygen in blood of infants under 6 months

Methemoglobinemia

Converts hemoglobin, reducing blood oxygen-carrying capacity

Infants below 6 months can develop methemoglobinemia ('blue baby syndrome'). Combined nitrate+nitrite limit is 10 mg/L.
