title: Methemoglobinemia attributable to nitrite contamination of potable water through boiler fluid additives--New Jersey, 1992 and 1996.
abstract: Nitrite and nitrate ions are naturally occurring forms of nitrogen that can be present in ground and surface water and can be used as a food preservative because they inhibit the growth of Clostridium botulinum. Exposure to excessive levels of nitrite or nitrate may result in the acute syndrome of methemoglobinemia (MetHb), in which nitrite binds to hemoglobin. This report summarizes the findings of investigations of two incidents in which unintentional exposure to high doses of nitrite occurred through drinking potable water contaminated with additives to boiler conditioning fluids.
