Abstract

Methemoglobin levels were determined in the blood samples of 116 children (average age, 15 months) living in the State of S. Paulo (Brazil). Blood from two groups was analyzed: Group 1 was formed by 92 children who drank water with nitrate levels below 10 mg N/liter; whereas Group 2 was formed by 24 children who drank well water with nitrate above the level permitted. The methemoglobin average for Group 1 (0.56%) was statistically different and less that for Group 2 (0.76%).
