bioamplification, biomagnification (s) (noun)
; bioamplifications, biomagnifications (pl)
The increase in concentration of a pollutant from one trophic (or nutrition) level in a food chain to another; this usually occurs when the pollutant is metabolized and excreted much more slowly than the nutrients that are passed from one trophic level to the next: "Such bioamplification pollutants are long-lived, mobile, soluble in fats, and biologically active."
"Biomagnification, or bioamplification, is a particular threat for species living at the top of food chains."
