Researchers at Oregon State University are recruiting citizen scientists to join a network enabling air and water exposure monitoring in their communities. This site will allow scientists to develop a profile, perform online training, request a sampling site, and join in on local events. This site will also manage equipment loans, sample submission, and allow you to view your data. For more information, please visit the Citizen Science website. If you are interested becoming a citizen scientist, please sign up for updates and we will send you a newsletter when we open up registration for online training.
In recent years a high prevalence of neonatal foals born with neurological deficits (altered mentation and dysphagia) was observed at a horse farm located in Pennsylvania (PA). The farm proprietor also owned another farm in New York (NY) where mares and foals did not exhibit any unusual health outcomes. Both farms used identical animal husbandry practices and shared feed sources. Over the last 5 years the frequency of dysphagia in foals at the PA facility has increased from 25 to 92%. To evaluate potential farm-specific chemical impacts, passive sampling devices (PSDs) were deployed on brood mares at both farms continually over a two-year period. PSDs were also deployed in the ambient air and in well water at each farm. Collaborators from the Cornell Department of Population Medicine and Diagnostic Science also took biological samples from mares and foals (urine and blood) when appropriate.
Environmental Preparedness & Resilience Empowering People is a citizen science project which provides resources based on a low cost passive sampling platform. These samplers can be used to evaluate air quality and your personal environmental exposures. By leveraging resources developed for our Citizen Science project, we are recruiting and training citizen scientist to use our passive sampling platform to produce useful data prior to and post environmental disaster. Please visit eprep.oregonstate.edu to learn more and sign up.

Between 1980 and today, the number of geriatric cats (10+ years) diagnosed with feline hyperthyroidism has risen from 1 in 300 to 1 in 10. There is some evidence that exposure to flame retardants may contribute to the development of feline hyperthyroidism. Beginning summer 2017, FSES partnered with the OSU Veterinary School, Columbia University, and the Animal Endocrine Clinic to compare levels of flame retardants found in homes of hyperthyroid and non-hyperthyroid cats.

Sampling of polycyclic aromatic hydrocarbons (PAHs) in air and water in the Gulf of Mexico related to the Deepwater Horizon oil spill.
Only days after Harvey, OSU SRP researchers partnered with Texas A&M, UTHealth School of Public Health, and Baylor College of Medicine. The goal of the partnership is to place personal samplers on individuals living in and near hurricane-damaged areas. The passive sampling wristband is the perfect tool. It doesn’t need batteries or the internet. Additionally, the wristband can detect over 1,500 different chemicals.

The Oregon State University Superfund Research Center was established in 2008. The FSES laboratory houses the Analytical Chemistry Core and many SRP trainees working on research project 4 titled, "Bridging Superfund Site Based Bioavailable Extracts with Biology." The Superfund Research Program is federally funded and administered by the National Institute of Environmental Health Sciences (NIEHS grant #P42 ES016465), an institute of the National Institutes of Health.
