PUBLIC HEALTH RELEVANCE : The importance of the proposed ozone sensors with regard to public health is highlighted by the fact that EPA's stringent National Ambient Air Quality Standard (NAAQS) for ozone emission levels are exceeded in many parts of the US, and there is a tremendous need to better characterize the spatial and temporal distributions of ozone. The proposed research has significant potential to reduce health care costs by enhancing the understanding of causative exposure-dose respiratory health effects through improved accuracy and enhanced population size in public health studies. In conjunction with embedded sensors such as 3D accelerometers, heart rate, respiration rate, fitness tracking, and many more existing or proposed smart phone utilities, the proposed mobile personal exposure monitors can potentially enhance epidemiological population studies and gather rich metadata on environmental pollutants, and their exposure effects on humans, as a function of location, season and physical activity. The long-term vision of the proposed work (Phase 2 and beyond) is to develop reliable low-cost sensors to simultaneously measure the external exposure to multiple environmental pollutants, and integrate these chemical sensors with biosensors for measuring the levels of toxicants in biological specimens obtained from an individual, such as blood, saliva, exhaled breath, sweat or urine. Thus, the exposure measurements of the proposed sensor can be combined with diagnostic tools to assess an individual's internal dosage and physiological effects, thereby providing comprehensive exposure assessment from source to dose.
