Abstract:
Exposomics is an emerging area that concerns the comprehensive characterization of environmental factors to which people are exposed to across their lives and the impact of these factors on health. As the concept of exposomics gathers interest, there has been rapid advances in “exposomic senor” technologies. These sensors have emerged as a practical means to measuring many of the exogenous factors that constitute the external exposome, providing high chemical, spatial, and temporal resolution measurements of exposures at the population scale as well as at the individual-level. Among the most promising technologies with extensive chemical coverage are wearable passive samplers. These sensors when coupled with high resolution mass spectrometry can be used to detect exposure to unique mixtures of prevalent and emerging contaminants. Integration of exposomic data captured by these sensors with other omic datasets presents exciting opportunities for investigating disease risk. I will present a wearable passive sampler (Fresh Air wristband) developed by my group that has enabled prevalent chemical exposure to be quantified (i.e. volatile organic compounds, polycyclic aromatic hydrocarbons, pesticides, phthalates, nicotine, and flame retardants) and individualized mixtures to be characterized. I will also share findings from recent deployments of this exposomic sensor with various international cohorts. The comprehensive exposure assessment that is possible with passive samplers has enabled new opportunities to explore the health impacts of chemical exposures across vulnerable groups in less accessible regions of the world.

Short biography:
Dr. Pollitt is an assistant professor in Department of Environmental Health Sciences at the Yale School of Public Health. She also holds an appointment in the Yale School of Engineering and Applied Sciences in the Department of Chemical and Environmental Engineering. She earned her BASc and MASC in Chemical Engineering from the University of Toronto. She went on to complete her PhD at King’s College London with Professors Frank Kelly and Roy Harrison exploring the impact of traffic-related air pollutants on cardiorespiratory health. She was subsequently awarded a Canadian Thoracic Society Postdoctoral Research Fellowship at Toronto General Hospital and the University of Toronto focused on linking complex air pollutant mixtures with respiratory disease outcomes. Dr. Pollitt’s current research combines her interests and expertise in air quality, exposure science, and analytical chemistry and aims to understand the influence of emerging environmental factors on health.
