Volunteers needed for air quality monitoring project
The City’s Environmental Services division is conducting a citywide air quality monitoring project and is looking for volunteers to help with the sampling by placing a canister at their home from Nov. 4 to 7.
To volunteer, you must:
- Live in Minneapolis.
- Have an appropriate place to set the air monitoring canister which is about 15” high and 8” wide. (The location must be outdoors and off the ground: a porch, table or chair will work. The location cannot be near where people smoke, so a shared patio of an apartment complex would not be a good location.)
- Be able to place the canister at your home from Nov. 4 through 7.
- Be able to return the canister to the Public Service Center on Nov. 8.
- Be willing to sign a consent form and attend a short demonstration before taking the sampler home.
If you are interested in helping, please contact firstname.lastname@example.org by Oct. 16. Be sure to include your home address with your zip code.
Study organizers will select locations to ensure sampling canisters are evenly distributed across the city. If your location is appropriate, you will receive an email notifying you that you have been selected to participate in the study. This map shows locations where volunteers are still needed.
About the study
The study is sampling air quality for volatile organic compounds (VOCs). Approximately 100 air sampling canisters will be placed throughout Minneapolis to obtain data for 77 different chemicals.
The canisters that will be used are summa canisters, which are stainless steel electro-polished (or "summa" polished) passivated vessels that can collect a whole air sample. To collect a sample, the summa canister valve is opened and the canister is left in a designated area for a period of time to allow the surrounding air to fill the canister and obtain a representative sample. The valve is closed before the canister is sent to a laboratory for analysis.
