Proposed Project: Assessment of Methemoglobin Levels in Pregnancy—New—National Center for Environmental Health (NCEH), Centers for Disease Control and Prevention (CDC).

Background

Methemoglobinemia as a consequence of ingestion of nitrate-contaminated water has been well established. Methemoglobinemia is an acute and potentially fatal illness, the severity of which depends on the amount of methemoglobin (metHb) formed. Subclinical increases in metHb levels can occur in people exposed to low levels of nitrate in drinking water; however, metHb levels in such people have not been well characterized. Furthermore, very little is known about metHb levels in pregnant women, including whether drinking low levels of nitrate (below the maximum allowable contaminant level of 10 mg/L) affects blood metHb levels in pregnant women or their fetuses. We propose to study 330 pregnant women who consume water from public and private wells. We plan to follow them from their first prenatal visit until 2 weeks after delivery, when we will also measure metHb levels in their newborn infants. The study objectives are to (1) measure metHb levels throughout pregnancy and evaluate how metHb levels change during and just after pregnancy; (2) measure metHb levels within a population of women and their newborn infants who are served by either public or private water supplies and are exposed to a range of nitrate levels primarily below the maximum contaminant level for public water supplies; (3) provide additional medical care, education, and advice to women whose metHb levels are elevated (above 5% of the total hemoglobin); and (4) to provide education and advice to women whose water supplies have elevated nitrate levels with regard to the potential hazards of infant methemoglobinemia. There is no cost to respondents.
