bioaccumulation

the process of concentration of chemical contaminents in animal tissues as they move higher up the food chain e.g. pesticides and heavy metals stored in fatty tissues are passed on from one predator to a higher predator, the resulting concentrations being increasingly harmful and most so to the top predators.
