Investigation on the relationship between bioconcentration factor and distribution coefficient based on class-based compounds: The factors that affect bioconcentration

Environmental Toxicology and Pharmacology, 2014
Bioconcentration factor (BCF) is one of the most important parameters in the assessment of the potential hazard of new compounds in aquatic ecosystems. However, the factors that influence the estimation of BCFs for a large variety of chemicals have not been systemically investigated in the literature. In this paper, a large BCF data set containing 1088

Measuring and Estimating the Bioconcentration Factor of Chemicals in Fish [PDF]

Journal of the Fisheries Research Board of Canada, 1979
A method of estimating the bioconcentration factor of organic chemicals in fathead minnows (Pimephales promelas) is described. Water at 25 °C was intermittently dosed with the chemical at a nontoxic concentration in a flow-through aquarium. Thirty minnows are placed in the aquarium, and composite samples of five fish are removed for analysis after 2 ...

Fuzzy filtering for robust bioconcentration factor modelling

Environmental Modelling & Software, 2009
This study introduces a fuzzy filtering based technique for rendering robustness to the modelling methods. We consider a case study dealing with the development of a model for predicting the bioconcentration factor (BCF) of chemicals. The conventional neural/fuzzy BCF models, due to the involved uncertainties, may have a poor generalization performance

The bioconcentration of zinc by Gammarus pulex (L.) and the application of a kinetic model to determine bioconcentration factors

Water Research, 1993
Abstract The bioconcentration, and subsequent elimination, of zinc by the freshwater amphipod Gammarus pulex (L.) were determined experimentally in the laboratory at five zinc exposure concentrations (0.41–2.02 mg/l). A first-order kinetic model, modified for naturally occurring trace chemicals, was then used to calculate uptake ( K 1 ) and ...
