The bioconcentration factor (BCF) is the ratio of the concentration in an organism to that in the surrounding water at steady state, uptake from water only. Bioaccumulation is the build-up in an organism from all routes, food included; biomagnification is the increase of concentration from prey to predator up a food chain.
