A total of 898 people from Yellowknife, Ndilo and Dettah participated in the arsenic study in the fall 2017. Participants will receive their results for urine in a personal letter in June 2018!

We will send the results of your toenail analysis in the Fall of 2018. Your saliva results will be grouped with all participants and the general results shared at community meetings sometime in late 2018 or early 2019.

Send us a quick e-mail and we’ll contact you to set up an appointment.

If you are a North Slave Métis Alliance (NSMA) member or a Yellowknives Dene First Nation (YKDFN) member, please mention it in the letter above. These two communities are being assessed as two different groups.

If you are not members of NSMA or YKDFN, the following applies to you.

What does it Mean to be "Randomly Selected"?

A volunteer can only represent himself, whereas a random participant represents the population.

From a statistical point of view, randomly selected participants are key in ay scientific study. It leads to a real representation of the studied population and ensures that we sample a wide variety of people. Therefore, we randomly selected 1000 households in Yellowknife where we aim to interview 1 adult and 1 child (if applicable). If you received a letter in the mail, you are one of them! You won the lottery!

Why is My Participation Important?

Participation from randomly selected households are highly valuable for this study. The higher the participation rate we have, the more accurate our results will be.

You will receive a $50 gift card of grocery as a thank you.

You will also receive your confidential personal results in the mail once they are ready (around Spring 2019).

Who can Participate in My House?

Within the selected household, we need to randomly select participants! We sample one adult (18 – 79 years old) and one child (3-17 years old) who have lived in Yellowknife for the past 12 months. When more than one eligible person lives in the house, we ask this simple question:

  • “Whose birthday is next?” (among adults, and among children).
* Participating children also get a $50 gift card plus a small gift.

What does it Involve?

A short interview of about 30 minutes that can be conducted in your house or other chosen area (our office, your office, coffee shop, etc.). You will also be asked to collect your biological samples (saliva, toenail and urine) at your own convenience.
