DESCRIPTION:Dr Krystal Pollit\, Assistant Professor\, Department of Enviro
 nmental Health Sciences\, Yale School of Public Health\, USA\nAbstract:\nE
 xposomics is an emerging area that concerns the comprehensive characteriza
 tion of environmental factors to which people are exposed to across their 
 lives and the impact of these factors on health. As the concept of exposom
 ics gathers interest\, there has been rapid advances in “exposomic senor
 ” technologies. These sensors have emerged as a practical means to measu
 ring 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. A
 mong 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 pr
 evalent 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 che
 mical exposure to be quantified (i.e. volatile organic compounds\, polycyc
 lic 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 vario
 us international cohorts. The comprehensive exposure assessment that is po
 ssible with passive samplers has enabled new opportunities to explore the 
 health impacts of chemical exposures across vulnerable groups in less acce
 ssible regions of the world.\n\nShort biography:\nDr. Pollitt is an assist
 ant professor in Department of Environmental Health Sciences at the Yale S
 chool of Public Health. She also holds an appointment in the Yale School o
 f Engineering and Applied Sciences in the Department of Chemical and Envir
 onmental 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 Res
 earch Fellowship at Toronto General Hospital and the University of Toronto
  focused on linking complex air pollutant mixtures with respiratory diseas
 e outcomes. Dr. Pollitt’s current research combines her interests and ex
 pertise in air quality\, exposure science\, and analytical chemistry and a
 ims to understand the influence of emerging environmental factors on healt
 h.\n
