Yes. That's a really good question.
One example I can tell you about is the project I did last year. We collected water and soil samples from Yellowknife around Great Slave Lake. It was really community-based. We had community members on the team. We tried to identify the amount of PBDEs. That is a very typical flame retardant, and it's claimed to be an emerging contaminant. It's toxic, carcinogenic and everywhere, from our sheets to our cars to our appliances.
We collected more than 150 samples of soil and water. Surprisingly, there was almost 100% detection of PBDEs. They're not only on the surface; they're also deep, even in the permafrost. Those contaminants are now everywhere. Even microplastics go very deep. We detected microplastics 1.5 metres deep, and you can drill permafrost like concrete.
Those things are already there. How do we protect our communities from that when it's in the rivers and the lakes and the food—in the food and water?
