Abstract Details

2011, Master of Science, Ohio State University, Public Health.
Particulate matter (PM) is a mixture of pollutants that have been associated with various adverse health effects. Since concentration levels of PM vary across space and time, the association between exposure to particle pollution and health on both spatial and temporal scales has been a cause of concern. In this study, we conducted time and space resolved personal monitoring to demonstrate the capability and explore models and methods of analysis to advance our ability to examine both PM’s health threat as well as source contribution. In addition, we examine the possible sources that may account for rapid increases in exposure levels. At the same time, geospatial monitoring was used to record time and location of the subject during monitoring. Perceived surrounding changes and human activities were recorded by voice recorder and activities diary. The monitoring data of personal PM exposure were collected around and on the campus of The Ohio State University. To simplify the geographic data, microenvironments were applied, which divided the study areas into five categories: indoor at home, outdoor, indoor on campus, in transit and others, respectively. Further statistical analyses were conducted to test our hypotheses on personal exposure in those microenvironments. Significant differences of personal exposure levels have been observed between different microenvironments, as well as between some locations in the same microenvironment. Some personal activities, such as cooking and cleaning, were found to increase personal exposure level. Additionally, geo-visualization was applied to present the convenience of visualization of personal exposure on a space-time scale, which can help to understand the influence of personal habits and activities on personal exposure. Results in this study demonstrated the significant variation of personal exposure levels across different microenvironments, as well as the significant increase of personal exposure levels associated with some activities. With space-time integrated personal monitoring PM data, a map was generated and visually showed the small-scale temporal and spatial variability of personal exposure.
