Great Lakes Passive Sampling is a research project being conducted by the Lohmann Lab at the University of Rhode Island Graduate School of Oceanography. By deploying polyethylene passive samplers in the water and air throughout the Lake Ontario and Lake Erie region, we can measure levels of persistent hydrophobic organic pollutants and analyze how the amounts of these chemicals change at different locations.
Polyethylene passive samplers are essentially just pieces of plastic that can absorb hydrophobic contaminants from the air or water. To obtain data in many different areas, we depend on a network of volunteers.

Passive Sampling by Volunteers
We are currently wrapping up the 2013 sampling season. Our final round of samplers will be recovered in October. For more information on volunteering next year in your area, visit the Volunteer Resources Page, or feel free to contact us. You can also check us out on Facebook.
2013 Sampling Sites: Focus on Cleveland
In 2013, samples were placed throughout the greater Cleveland area to learn more about how air pollutants from urban sources travel into other regions. Samplers were deployed by many helpful groups of volunteers, including the Cleveland Department of Public Health and high school students at Hathaway Brown School.
