Webpossible the bioconcentration factor is calculated preferably both as the ratio (BCF ss) of concentration in the fish (C f) and in the water (C w) at apparent steady-state and as a kinetic bioconcentration factor, BCF K (Annex 1.5) as the ratio of the rate constants of uptake (k 1) and depuration (k 2) assuming first-order kinetics(3). 8. Web13 de ago. de 2024 · The bioconcentration factor (BCF) and translocation factor (TF) were estimated for heavy metal uptake capacities of plants. Bioconcentration factor (BCF) is the ratio of the content of metals in various parts of a plant to that in the soil (Liu et al. 2009). If the BCF ≤ 1.00, it indicates the plant can only absorb but not accumulate metal.
