A lot of those communities eat a lot of fish and a lot of sea mammals. The sea mammals, because they're at the top of the food chain, are very contaminated with PFAS. They end up having a higher burden and a higher load of PFAS because of what they eat.
It's better for them to eat fish and sea mammals because it's very nutritious. It's a high-quality food compared to fast food or the alternatives.
Yes, there's definitely a higher burden on them, but I want to emphasize that the fish at the supermarket is also loaded with PFAS. It's the fish that you're buying and eating, but it's not at the same level as some of those indigenous communities that really depend on it for food.
