Of all environmental chemical transport processes, diffusion is the only continuously active process, and currently has been used as a baseline for total flux. However, contaminants can also move through the environment via wave pumping, tidal pumping, or
The Food Safety and Environmental Stewardship Laboratory is very interested in understanding the effect of wildfires on air quality. We have begun collecting samples before, during and after wildfires in the Pacific Northwest using community-engaged resea
FSES and colleagues at Wake Forest are using the lapel version of the silicone passive sampler to define exposures to Ag workers in North Carolina
Passive sampling devices were deployed in air, water, and on brood mares at two horse farms, one in Pennsylvania and one in New York.
Using wristband samplers, smart phones and a hand held spirometer, an active study in Eugene Oregon is looking at lung function in asthmatics and chemical exposures associated with location
FSES and FEMA working together, using passive samplers to characterize firefighter chemical exposure
FSES researchers were boots-on-the-ground within two weeks of hurricane Harvey's devestation of the Gulf coast. With local collaborators FSES distributed wristbands to residents to characterize their exposures during clean-up efforts.
Using the same material as is used in the wristbands, FSES developed Feline Passive Samplers, simple small samplers that can be worn by cats (or dogs) that will allow determinations of flame retardant exposures
If silicone can be used as a passive sampler in aqueous deployments, could it be used to sample the atmosphere?
FSES field teams deploying samplers in Mosier OR to characterize the results of an oil-train derailment and fire.
If silicone can be used as a passive sampler in aqueous deployments, could it be used to sample the atmosphere?

Research Highlight:
Research Continued through the Covid-19 pandemic
Adhering to the university and state guidelines, we continued to conduct research in 2020. We deployed samplers on the Columbia river as well as through the mail in our wildfire air quality sampling study.
Silicone Wristband Personal Monitoring Device
Accurately assessing a person’s exposures to putative environmental toxicants is central to the challenge of determining environmental health effects. The lack of low cost, easy-to-use personal sampling technology hinders our ability to understand the effect of the environment on health.
We are developing common wristbands to serve as passive samplers that quantify chemical exposure from our environment. We have shown these simple wristbands, when appropriately prepared provide a simple solution for studies into chemical exposures. With our powerful and sensitive analytical techniques refined over two decades, over 1500 common environmental contaminants can be analyzed for low cost.
If you would like to know more, please see the full publication and follow the additional research we are pursuing with the wristbands (see more here). You can also contact us for more information or to suggest a collaboration.
Our state-of-the-art facility contains two identical Agilent 7890A - 5975C GC-MS systems, an Agilent GC-ECD 6890, a Markes Unity thermal desorption chamber coupled with an Agilent 6890A - 7000 GC-MS and two triple-quadrupole Agilent 7890A - 7000 GC-MS-MS systems. This array of instruments allows us to couple high-throughput analytical chemistry with extraordinary sensitivity, accuracy and precision.
A new addition to the group capabilities, a new Gas Isotope Ratio MS unit targeted towards forensic source identification.
