Webestimates of the bioconcentration factor (BCF, sometimes denoted as K B) for organic chemicals with log K OW values up to about 9.0 can be obtained using the equation of Bintein et al. (13). The pre-estimate of the bioconcentration factor for such strongly hydrophobic substances may be higher than the steady-state bioconcentration factor … WebThe information on aquatic species, other than fish, that pertains to bioconcentration factors, metabolism, and elimination is rather limited in the literature.

Bioconcentration can be described by a bioconcentration factor (BCF), which is the ratio of the chemical concentration in an organism or biota to the concentration in water: $${\displaystyle BCF={\frac {Concentration_{Biota}}{Concentration_{… In aquatic toxicology, bioconcentration is the accumulation of a water-borne chemical substance in an organism exposed to the water. There are several ways in which to measure and assess See more A bioconcentration factor greater than 1 is indicative of a hydrophobic or lipophilic chemical. It is an indicator of how probable a chemical is to bioaccumulate. These chemicals have high lipid affinities and will concentrate in tissues with high lipid content instead of … See more In determining the degree at which bioconcentration occurs biological factors have to be kept in mind. The rate at which an organism is exposed through respiratory surfaces and contact with dermal surfaces of the organism, competes against … See more Regulatory uses Through the use of the PBT Profiler and using criteria set forth by the United States Environmental Protection Agency under the Toxic Substances Control Act (TSCA), a substance is considered to be not bioaccumulative if it … See more Predictions Bioconcentration factors facilitate predicting contamination levels in an organism based on chemical concentration in surrounding water.
