Supporters of EVISA includes:


biomagnification factor, B

Ratio of concentrations of a compound at two consecutive trophic levels at steady state. It can also be
expressed in terms of a rate constant-based bioaccumulation model

B = Cn/Cn–1= αf/ke

where α is assimilation efficiency, f is feeding rate, and ke is the first-order elimination constant. B can be calculated from field data on assumed trophic relations or from laboratory feeding experiments.
See also: trophic enrichment factor.
