The prediction of bioconcentration in fish

Water Research, 1984
Abstract Fish bioconcentration factors (BCF) are used for the prediction of the environmental effects of new chemicals and some studies have proposed that they can be predicted from physico-chemical properties of the chemical. Values have been taken from the literature for octanol:water partition coefficients (P) and water solubilities (WS) of ...

Advances in bioconcentration prediction

Chemosphere, 1988
Abstract A reexamination of the log-log relationship between the bioconcentration factor in fish (BCF) and different types of POW data for a set of 49 compounds of diverse chemical range reveals that the overall correlation between log BCF and log POW is only moderate but gets significantly improved by restriction to the subset of CHCs and PAHs ...

Bioconcentration and Phytotoxicity of Cd in Eichhornia crassipes

Environmental Monitoring and Assessment, 2006
Plants of Eichhornia crassipes grown at various levels of cadmium ranging from 0.1 to 100 microg ml(-1) accumulated Cd in a concentration and duration dependent manner. At all levels, Cd accumulation by various plant tissues followed the order roots shoot leaves.

Bioconcentration of lipophilic organochlorines in ovine dentine

Archives of Oral Biology, 2001
The bioconcentration of lipophilic organochlorines in ovine dentine in comparison to adipose tissue was examined. Sheep were given a single dose (0.2-1.4 mg/kg body wt) of individual polychlorobiphenyl (PCB) congeners (tetrachlorobiphenyls IUPAC Nos. 54 and 80, and hexachlorobiphenyls IUPAC Nos.

The Bioconcentration of 131I in Fresh Water Fish

Health Physics, 1996
The dynamic characteristics of the radionuclide concentration process in fresh water fish have been studied. The experimental data for the tilapias were fitted using a simple compartment model to get characteristic parameters such as concentration factors, elimination rate constants, and initial concentration rates, which are 3.08 Bq kg-1/Bq L-1, 0 ...

Bioconcentration of methylmercury in microzooplankton in a temperate river

Environmental Toxicology and Chemistry, 2011
Abstract To understand the bioconcentration of methylmercury (MeHg) at the base of the riverine food chain, we determined levels of dissolved organic carbon, microseston, Hg, and MeHg in surface water in relation to the microzooplankton MeHg from Yeongsan River.

Prediction of Bioconcentration Factors in Fish and Invertebrates Using Machine Learning

Science of the Total Environment, 2019
The application of machine learning has recently gained interest from ecotoxicological fields for its ability to model and predict chemical and/or biological processes, such as the prediction of bioconcentration.

The “bioconcentration” aspects of DDT in the environment

1976
The term bioconcentration is not listed in any of the English language dictionaries; it is a compound word which combines the prefix bio, meaning life, and concentration, which means many things, but in the connotation of this text it refers to the accumulation of a pesticide in a living organism.

Biotransformation and bioconcentration of pyrene in Daphnia magna

Aquatic Toxicology, 2003
Water fleas (Daphnia magna) were exposed to [14C]pyrene in the presence and absence of piperonyl butoxide (PBO), a general cytochrome P450 (CYP) inhibitor, in organic carbon-free artificial freshwater (AFW ...
