I was a little surprised that the values are higher for humans than dogs b/c I am used to seeing dogs gnaw on any random thing, trying to drink from puddles, etc, which I would have thought would lead to higher intake. But ... is it just that this is these bioaccumulate and humans live longer and eventually have higher levels? Or do people actually have a higher intake through e.g. hot beverages in lined disposable cups, plastic cutlery and takeout containers, etc?
