biomagnification

   Also found in: Encyclopedia, Wikipedia 0.01 sec.
biomagnification  (b-mgn-f-kshn)
The increasing concentration of a substance, such as a toxic chemical, in the tissues of organisms at successively higher levels in a food chain. As a result of biomagnification, organisms at the top of the food chain generally suffer greater harm from a persistent toxin or pollutant than those at lower levels. Compare bioaccumulation.
