Bioconcentration Factor (BCF) and Translocation Factor (TF) of Heavy Metals in Mangrove Trees of Blanakan Fish Farm [PDF]

Makara Journal of Science, 2017
In the mangroves of Blanakan, Indonesia, silvofishery practices may play a role in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials.

QSAR-QSIIR-based prediction of bioconcentration factor using machine learning and preliminary application

Environment International, 2023
Bioconcentration factor (BCF) is one of the important parameters for developing human health ambient water quality criteria (HHAWQC) for chemical pollutants. Traditional experimental method to obtain BCF is time-consuming and costly.

QSPR Modeling of Bioconcentration Factors of Nonionic Organic Compounds [PDF]

Environmental Health Insights, 2010
The terms bioaccumulation and bioconcentration refer to the uptake and build-up of chemicals that can occur in living organisms. Experimental measurement of bioconcentration is time-consuming and expensive, and is not feasible for a large number of chemicals of potential regulatory concern.

Predicting the bioconcentration factor of highly hydrophobic organic chemicals

Food and Chemical Toxicology, 2014
Bioconcentration refers to the process of uptake and buildup of chemicals in living organisms. Experimental measurement of bioconcentration factor (BCF) is time-consuming and expensive, and is not feasible for a large number of chemicals of regulatory concern. Quantitative structure-activity relationship (QSAR) models are used for estimating BCF values

An alternative QSAR-based approach for predicting the bioconcentration factor for regulatory purposes

ALTEX, 2014
The REACH (Registration, Evaluation, Authorization and restriction of Chemicals) and BPR (Biocide Product Regulation) regulations strongly promote the use of non-animal testing techniques to evaluate chemical risk. This has renewed the interest towards alternative methods such as QSAR in the regulatory context. The assessment of Bioconcentration Factor

An assessment of the bioaccumulation of estrone in Daphnia magna [PDF]

, 2004
The bioaccumulation of estrone by Daphnia magna was determined. Direct uptake via the aqueous medium occurred within the first 16 hours. A bioconcentration factor of 228 was established over all temporal periods.

A new bioconcentration factor model based on SMILES and indices of presence of atoms.

European journal of medicinal chemistry, 2010
Indices of the presence of atoms (IPA) encode the presence or absence of atoms, such as nitrogen, oxygen, sulphur, phosphorus, fluorine, chlorine, and bromine in a molecule.

Evaluation of Published Bioconcentration Factor (BCF) and Bioaccumulation Factor (BAF) Data for Per‐ and Polyfluoroalkyl Substances Across Aquatic Species

Environmental Toxicology and Chemistry, 2021
Per‐ and polyfluoroalkyl substances (PFAS) are a group of man‐made chemicals of concern across the globe, and some of the PFAS chemicals are known to be bioaccumulative in aquatic species.

Predicting bioconcentration factor and estrogen receptor bioactivity of bisphenol a and its analogues in adult zebrafish by directed message passing neural networks.

Environment International, 2022
The bioconcentration factor (BCF) is a key parameter for bioavailability assessment of environmental pollutants in regulatory frameworks. The comparative toxicology and mechanism of action of congeners are also of concern.
