The main objective of this research 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, multipollutant exposures and cardiovascular health status were measured repeatedly for two cohorts: individuals with chronic obstructive pulmonary disease (COPD) and recent myocardial infarctions. For the Steubenville study, multipollutant 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, heart rate variability (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 PM, ozone, carbon monoxide, and nitrogen dioxide also were measured on each of the monitoring days.
Our analysis of the toxic effects of indoor and outdoor particles using in vitro bioassays was published in Environmental Health Perspectives (Long, et al., 2001). In this study, particle-induced proinflammatory responses were assessed using tumor necrosis factor (TNF) production in the macrophages. TNF production was significantly higher for indoor as compared to outdoor particles, both before and after normalization for endotoxin concentrations. Indoor and outdoor particle samples also were collected in 46 homes in Atlanta, GA, and will undergo a similar analysis to investigate the relative toxicity of indoor and outdoor particles.

During the next year, the data analysis from the Atlanta study will be completed, and a paper will be submitted to a peer-reviewed journal by the end of this year. Laboratory analysis of the electrocardiogram data from Steubenville currently is ongoing, with data analysis expected to start early next year.
