The overall objective of this project is to improve our ability to characterize air pollutant exposures for health effects studies. This project is one of three research studies proposed under Theme I: Assessing Particle Exposures for Health Effects Studies that were based on personal, indoor, and outdoor particulate and gas concentrations that were measured as part of our previous or current exposure studies. This project was intended to address Particulate Matter Research Topics 2 and 8 identified by the National Research Council (NRC)-Exposures of Susceptible Populations and Assessing Effects of Hazardous Particulate Components. The main objective of this project is to investigate the joint and individual effects of outdoor and indoor particles on heart rate and heart rate variability.
We have completed data collection for two field studies conducted in Atlanta and Steubenville, both of which have been co-sponsored by the Center. For the Atlanta study, multi-pollutant exposures and cardiovascular health status were measured repeatedly for two cohorts: individuals with COPD and recent myocardial infarctions (MIs). For the Steubenville study, multi-pollutant exposures and cardiovascular health status were measured for elderly individuals living in government-subsidized housing complexes. The same health protocol was used for each of these studies, with data on heart rate, HRV, blood pressure, oxygen saturation, and daily symptoms obtained for each participant on at least 7 days. Twenty-four-hour indoor, outdoor, and personal measurements of particles, ozone, carbon monoxide, and nitrogen dioxide also were made on each of the monitoring days. Laboratory and data analysis from the Atlanta study currently is under way, with some results expected to be presented at the 2001 International Society of Environmental Epidemiology (ISEE) conference in Germany this September. Laboratory analysis of the Steubenville data currently is ongoing, with data analysis expected to start this coming summer. Results from both studies will be reported within the next couple of years.
We also have examined the toxic effects of indoor and outdoor particles using in vitro bioassays. Bioassays were performed using rat alveolar macrophages for 14 paired indoor and outdoor PM2.5 samples collected from nine Boston area homes (Long, et al., in press). Particle induced pro-inflammatory responses were assessed using tumor necrosis factor (TNF) production in the macrophages. Results from this study indicated that TNF production was significantly higher for indoor as compared to outdoor particles, both before and after normalization for endotoxin concentrations.
Laboratory and data analysis from the Atlanta study will continue, and some results are expected to be presented at the 2001 ISEE Conference in Germany in September 2000. Laboratory analysis of the Steubenville data will continue, with data analysis expected to start this coming summer. Results from both studies will be reported within the next couple of years.
