Thank you.
Dr. Schindler, yesterday afternoon we had presentations from various leaders and elders in the Fort Chipewyan area, and they brought up a number of anecdotal examples of fish deformities and concerns around that. Obviously your charts with the parts per billion and parts per trillion indicate the impacts of the magnification of those effects that go up the food chain.
I know you mentioned the larval examples of contamination and bitumen. I'm just wondering about the transition between what the native wisdom is telling us anecdotally around deformations and concretely in Lake Athabasca.
