Description:

Objective:

The overall objectives of the RIOPA study were:

  1. Investigate the relationships of indoor, outdoor, and personal air concentrations of VOCs, carbonyl compounds, and PM2.5, and in-vehicle concentrations of carbonyl compounds.
  2. Quantify the outdoor contribution to indoor and personal air concentrations of the measured pollutants.

A secondary objective of the study was to make paired measurements in the adults and children to determine whether air toxic exposure estimates of adults could be used for children.

The specific aims of the study were to:

  1. Compare indoor, outdoor, and personal air (and in-vehicle for carbonyl compounds) concentrations of the pollutants measured in the RIOPA.
  2. Examine the effects of a number of variables (e.g., season, house type, city/state) on measured concentrations and indoor/outdoor relationships.
  3. Quantify the contribution of outdoor sources to indoor concentrations of the measured pollutants.
