Passive sampling eyewear
Lead Researchers: Jenny li liao, Sara Vaezafshar, Fiona Cook
Wearable passive samplers are accessible and efficient tools to detect and quantify an individual or population’s chemical exposures. In contrast, the current gold standard of active air samplers are loud, bulky and expensive, making them not ideal for large-scale studies. Current wearable passive sampler designs are limited by their far distance from inhalation pathways and tendency to contamination. To address these limitations, we are proposing eyewear such as glasses to be used in passive sampling. We will measure uptake rates of chemicals onto eyewear deployed within a lab and to participants. Future work will involve using passive sampling eyewear to conduct population-level chemical exposure studies.
