Fish Bioconcentration factors (BCF) were derived from data generated in the dietary study with rainbow trout using the 15 models within the OECD TG 305 BCF estimation tool and all BCFs predicted except one (method 3) were above 5000.
The extent of bioaccumulation is quantitatively expressed by the Bioconcentration Factor (BCF), which is the ratio of the concentration of a contaminant in the organism and its average concentration in water.

More Definitions of Bioconcentration

Bioconcentration means the uptake and retention of substances by an organism from its surrounding medium.

Bioconcentration means the process leading to a higher concentration of a substance in an organism compared to the concentration of the substance in the environmental media to which the organism is exposed.

Bioconcentration means the net accumulation of a sub- stance by an aquatic organism as a result of uptake directly from the ambient water through its gill membranes or other external body surfaces.

Bioconcentration means the net result of uptake, transformation and elimination of a substance in an organism due to waterborne exposure.

Bioconcentration means an increase in concentration of a chemical and its metabolites in an organism (or specified tissues thereof) relative to the concentration of the chemical in the ambient water acquired through contact with the water alone. "Carcinogen" means a chemical which causes an increased incidence of benign or malignant neoplasms, or a statistically significant decrease in the latency period between exposure and onset of neoplasms in at least one mammalian species or man through epidemiological or clinical studies. "EC-50" means the concentration of a substance or effluent which causes a given effect to 50% of the exposed organisms in a given time period. "LC-50" means the concentration of a toxic substance or effluent which is lethal to 50% of the exposed organisms in a given time period. "LOAEL" or "Lowest Observable Adverse Effect Level" means the lowest tested concentration of a chemical or substance which produces a statistically significant increase in frequency or severity of non-overt adverse effects between the exposed population and its appropriate control. "MATC" or "Maximum Acceptable Toxicant Concentration" means the value obtained by calculating the geometric mean of the lower and upper chronic limits from a chronic test. A lower chronic limit is the highest tested concentration which did not cause the occurrence of a specified adverse effect. An upper chronic limit is the lowest tested concentration which did cause the occurrence of a specified adverse effect and above which all tested concentrations caused such an occurrence. "NOAEL" or "No Observable Adverse Effect Level" means the highest tested concentration of a chemical or substance which does not produce a statistically significant increase in frequency or severity of non-overt adverse effects between the exposed population and its appropriate control. "Resident or Indigenous Species" means species which currently live a substantial portion of their lifecycle or reproduce in a given body of water,
