08-1 Relationship of Indoor, Outdoor and Personal Air (RIOPA): Further analyses of the RIOPA study data

Not Active
RFA 08-1

RFA 08-1 seeks proposals for studies that will take advantage of previously collected data on the concentrations of volatile organic compounds, carbonyls, and PM2.5 in indoor, outdoor, and personal air for subjects living in three urban centers with different pollution sources and weather. These data can be accessed on a publicly available web-based relational database. A total of $300,000 is available under this RFA; HEI hopes to fund 3-5 studies.

This report describes a study to identify factors that influence exposure to volatile organic compounds (VOCs) and VOC mixtures. Dr. Stuart Batterman at the University of Michigan–Ann Arbor and colleagues used the extensive data that HEI posted on the Web from the Relationships of Indoor, Outdoor, and Personal Air (RIOPA) study (HEI Research Report 130 Parts I and II), and data from the National Health and Nutrition Examination Survey (NHANES), to characterize exposure distributions for 15 VOCs, with an emphasis on high concentrations. Factors examined included geographic location, weather, characteristics of participants' homes, and specific activities, such as pumping gas.

This report describes a study by Dr. Patrick Ryan at the Cincinnati Children’s Hospital Medical Center. He used the RIOPA data – which HEI has made available to all scientists on the Web to further explore relationships among the elemental composition of indoor, outdoor, and personal PM2.5 samples collected at participant’s homes. His analyses included traditional and novel approaches to comparing the samples.
