Objective:

The RIOPA study was funded by the NUATRC in response to RFA 96-01. The project comprised of three studies initially independently funded:

  • A study funded by NUATRC with Dr. Clifford Weisel at Environmental and Occupational Health Sciences Institute (EOHSI) as principal investigator;
  • A study funded by the Health Effects Institute (HEI) with Dr. Jim Zhang of EOHSI as principal investigator; and
  • A study funded by HEI with Dr. Barbara Turpin of Rutgers University as principal investigator

Because the two HEI studies complemented and added to the initial study funded by NUATRC, both organizations have treated the three studies as one so that the results could be reported in a coherent manner.

The overall objectives of the RIOPA study were:

  1. To investigate the relationships of indoor, outdoor, and personal air concentrations of VOCs, carbonyl compounds, and PM2.5, and in-vehicle concentrations of carbonyl compounds, and
  2. To 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.
  4. Determine indoor source strengths of the measured pollutants that are primarily generated indoors.

The results for the study show that personal and indoor air concentrations of many measured VOCs and carbonyl compounds were dominated by indoor sources. Several measured species had personal concentrations higher than either indoor or outdoor concentrations, indicating the presence of some sources closely related to personal activities. Some species had no significant indoor sources in the majority of the RIOPA homes, and thus indoor concentrations were mainly determined by outdoor concentrations in these homes. The range of distributions of air concentrations measured for the VOCs, formaldehyde, acetaldehyde, PM2.5, and air exchange rates, were generally consistent with values reported previously in the literature.

Summary/Accomplishments (Outputs/Outcomes):

  • This project was funded in response to RFA 96-01 “Personal Exposure to Air Toxics in Urban Environments.”
  • The study is in compliance with Institutional Review Boards of the University of Medicine and Dentistry of New Jersey, (UMDNJ), Rutgers University, and the University of Texas. Human consent procedures met governmental guidelines. The study provided and followed appropriate quality control and quality assurance procedures.
  • The study started in 1997, and was scheduled to be completed in 2000.
  • A pilot study for the project was successfully completed during the first year. The goal of the pilot study was to test and optimize each component of the field-work and laboratory analysis procedures before finalizing procedures.
  • An inter-laboratory comparison of analytical techniques for VOC and aldehydes were comparable between EOHSI and its subcontractor the UT School of Public Health.
  • A site-visit was held by HEI at the EOHSI site. The purpose of this site visit was to (1) discuss and evaluate progress on the study to date and (2) discuss data analysis plans. As a result of this site visit, the Center and HEI requested a data analysis plan, which was submitted in December 2000.
  • A series of no-cost extensions were given to this project through July 2003.
  • A Draft Final Report containing data on VOC, aldehydes, and PM2.5 was submitted in March 2002.  A Revised Final Report was received by the Center in April 2003. A Final Revised Report was received in January 2004.
  • A draft final report containing information on particle speciation was submitted in February 2004.
  • A revised final report was received in December 2004.
  • A combined Center Research Report Number 7/Health Effects Institute report Number 130 Part 1, “Relationships of indoor, outdoor, and personal air (RIOPA) Part I. Collection methods and descriptive analyses,” was published in 2005.
  • A combined Center Research Report Number 10/Health Effects Institute report Number 130 Part II, “Relationships of indoor, outdoor, and personal air (RIOPA) Part II. Analyses of concentrations of particulate matter species,” was published in 2007.
