||The study's primary goal was to investigate the relationship of select air pollutant concentrations and their sources measured at community air monitoring stations in comparison to those measured in various neighborhoods in Wayne County, Michigan. Six primary data analysis objectives were components of the original study design. These original data analysis objectives were to: (1) characterize spatial and temporal relationships between pollutants; (2) determine human exposure factors; (3) determine environmental exposure factors; (4) develop enhanced human exposure models; (5) establish source contributions; and (6) investigate multi-pollutant (particulate matter/gases/semi-volatiles) relationships. The study was designed to significantly contribute to our understanding of how well air quality information collected at community monitors accurately reflects what neighborhoods and the individuals living in these neighborhoods are exposed to every day. It would provide needed information on defining what factors affect an individual's exposure to various particulate matter and air toxic sources. Exposure-related data from the DEARS can be divided into five main parts: (1) personal monitoring; (2) residential indoor monitoring; (3) residential outdoor monitoring; (4) monitoring performed at a central community site; and (5) survey information related to environmental and human exposure factors. The personal and residential monitoring involved a total of 145 participants over a three-year period of data collection. A total of nearly 36,000 individual 24-hr based exposure measurements involving particulate matter, criteria pollutant gases and other air pollutants of interest were obtained during the field measurements.
