ABSTRACT The Exposure Assessment, Biomarkers and Environmental Sensing Facility Core (EABES-FC) provides EDGE investigators with access to state-of-the-art analytical methods, instrumentation and exposure science expertise, to stimulate their translational and population-based environmental health science research through inclusion of high quality exposure assessment. The specific focus for development efforts during the following 5-years include (i) Data automation and visualization tools for sensor networks and mobile monitoring data, (ii) Personal & networked volatile organic compound (VOC) sensors integrated with existing low-cost, GPS- enabled particle sensors, and (iii) sensor fusion to merge measurements from personal and community monitors with Geographical Information Systems (GIS) data to improve the accuracy of exposure assessments. The primary goal of the EABES Core is to provide Center investigators with access to state-of- the-art exposure assessment tools and approaches.
