> Do Tuna and other forms of life effectively act as a sort of biological filter collecting mercury over time though? Yes. This is called biomagnification. Basically, animals absorb heavy metals that are in the food they eat, but don't have an efficient way of excreting it again. Mainly since these metals are bound so they're fat soluble, not water soluble. The higher up in the food chain, the worse it gets. https://en.wikipedia.org/wiki/Biomagnification |
