Description:

Objective:

Nitrogen dioxide, a common indoor and outdoor air pollutant, is a by-product of high-temperature combustion. Motor vehicles and power plants are primarily responsible for the nitrogen dioxide in outdoor air. the U.S. Environmental Protection Agency, which establishes National Ambient Air Quality Standards (NAAQS) for nitrogen dioxide and other air pollutants, has set the NAAQS for nitrogen dioxide as an annual average of 53 parts per billion (ppb) (100 µg/m3). Although the annual average concentrations of nitrogen dioxide are well below 50 ppb in most regions of the United States, the standard is exceeded in areas of southern California, and short-term peaks of 100 ppb, and occasionally 200 ppb, occur in urban areas.

Indoor levels of nitrogen dioxide are often higher than outdoor concentrations, especially in homes where there are unvented heating and cooking appliances that utilize natural gas, kerosene, coal, or wood. Such exposures are of concern because some studies suggest that children exposed to nitrogen dioxide have more respiratory illnesses than those who are not exposed.

Although mild respiratory illnesses in infants and young children are quite common, more serious illnesses can be life-threatening and might increase the risk of developing lung disease later in life. The epidemiologic studies that have examined the role of nitrogen dioxide in childhood respiratory disease have produced inconsistent results, partly because of the difficulty of assessing exposures and measuring respiratory illness in a community setting. This study was conducted to address the limitations of previous studies and to help resolve whether exposure to nitrogen dioxide increases the incidence of duration, or both, or respiratory illness in infants.

Approach:

Drs. Jonathan M. Samet, John D. Spengler, and colleagues conducted a prospective investigation of 1,205 health infants living in homes with gas or electric stoves in Albuquerque, NM. Nitrogen dioxide exposures were carefully estimated from repeated measurements in multiple locations in the subjects' homes throughout the entire 18-month observation period. Respiratory illnesses were monitored prospectively using a surveillance system based on daily parental diaries of respiratory signs and symptoms. Parental reports of illness episodes were validated in a subset of the population by comparison with clinical diagnoses and microbiological testing. Potential confounding factors that influence respiratory infections were reduced by selecting subjects whose parents did not smoke or intend to use day-care services outside the home. Rigorous quality assurance procedures were implemented in all phases of the experimental protocol.
