When the main exposure route is through the organism’s meal, biomagnification occurs when the chemical concentration in the organism surpasses the chemical concentration in its food. Food web biomagnification refers to the progressive increase in chemical concentrations with increasing animal trophic status and is used to characterize trophic enrichment of pollutants within food webs. The words biomagnification and food web biomagnification are more strictly defined for hydrophobic organic pollutants to describe the thermodynamic condition in which an animal’s chemical potential surpasses its diet and surroundings and rises through successive trophic levels.
