Bioaccumulation

Gallery Bioaccumulation Hero Encounter Edu

Persistent chemicals, like some of the plasticisers used to make plastic water bottles, don’t break down naturally so remain in the environment for a very long time. They get absorbed by organisms at the bottom of the food chains and build up at higher levels. This process is known as bioaccumulation. If the lethal dose is reached, the organisms at the top of the food chain die.
