Biomagnification definition

Biomagnification means the process of bioconcentration and bioaccumulation by which tissue concentrations of bioaccumulated chemicals increase as the chemical passes up through two or more trophic levels. The term implies an efficient transfer of chemical from food to consumer, so that residue concentrations increase systematically from one trophic level to the next (USEPA 2000c).

Biomagnification means the incremental process through a food chain by which progressively higher contaminant concentrations are attained in organisms located at respective higher trophic levels in the food web.

Biomagnification means the increase in tissue concentration of a pollutant in aquatic organisms at successive trophic levels through a series of predator-prey associations, primarily occurring through dietary accumulation. The expression used to quantify this increase is the biomagnification factor or "BMF." For a given water body, the BMF is calculated as:

Biomagnification means the transport of toxic substances through the food chain through successive cycles of eating and being eaten and through the subsequent accumulation and concen- tration of these substances in higher-order consum- ers and predators.

Biomagnification means the incremental process within a food chain by which progressively higher contaminant concentrations are attained in organisms located at respective higher trophic levels (i.e. in organisms located) at higher levels in the food chain
