Objective:

The Relationship between Indoor, Outdoor, and Personal Air (RIOPA) study will test the hypothesis that personal exposure to air toxics is influenced by outdoor sources of these air toxics. Two hypotheses to be tested are:

• A measurable and significant portion of the indoor air concentrations, personal exposures, and breath concentrations of volatile organic compounds (VOCs), aldehydes, and respirable particulate matter (PM2.5) are contributed by outdoor sources; and

• Residential air exchange rates (AER) are a major determinant of the influence of outdoor air concentration on indoor air and personal exposure.

Approach:

This project was initiated by the Center in December 1997, under a previous EPA grant (Grant No. R824834C006), and it will continue under this follow-on grant. This study includes an experiment that involves 100 homes and 150 individuals (100 adults and 50 children) in each of the three urban centers with different air pollution source profiles: Los Angeles, CA, dominated by mobile sources; Houston, TX, dominated by industrial point sources; and Elizabeth, NJ, with a mixture of mobile and point sources. The study will measure indoor and outdoor air concentrations of VOCs, aldehydes, PM2.5, and AER, as well as personal exposure in adults and children in a set of two 48-hour sampling periods in the three distinct urban areas.

Expected Results:

Following this experiment, we expect to be able to:

• Estimate the fraction that outdoor sources contribute to indoor and personal air concentrations in three distinct urban centers; and

• Estimate the exposures to populations living in the three urban centers from outdoor toxic air emissions.
