Predicting the Bioconcentration Factor in Fish from Molecular Structures [PDF]
Toxics, 2022 The bioconcentration factor (BCF) is one of the metrics used to evaluate the potential of a substance to bioaccumulate into aquatic organisms. In this work, linear and non-linear regression QSARs were developed for the prediction of log BCF using ...

Growth-Correcting the Bioconcentration Factor and Biomagnification Factor in Bioaccumulation Assessments. [PDF]
Environ Toxicol Chem, 2019 Abstract We illustrate that the Organisation for Economic Co-operation and Development guideline 305 (OECD-305) for growth-correcting bioconcentration factors (BCFs) and biomagnification factors (BMFs) violates the mass-balance assumption underlying the definition of BCFs and BMFs and provides unrealistic estimates of BCFs and BMFs of ...

In silico local QSAR modeling of bioconcentration factor of organophosphate pesticides. [PDF]
In Silico Pharmacol, 2021 The persistent and accumulative nature of the pesticide of indiscriminate use emerged as ecotoxicological hazards. The bioconcentration factor (BCF) is one of the key elements for environmental assessments of the aquatic compartment. Limitations of prediction accuracy of global model facilitate the use of local predictive models in toxicity modeling of

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.

Predicting the bioconcentration factor of highly hydrophobic organic chemicals [PDF]
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

Predicting the bioconcentration factor through a conformation-independent QSPR study [PDF]
SAR and QSAR in Environmental Research, 2017 The ANTARES dataset is a large collection of known and verified experimental bioconcentration factor data, involving 851 highly heterogeneous compounds from which 159 are pesticides. The BCF ANTARES data were used to derive a conformation-independent QSPR model.

The Use of the Index of Ideality of Correlation to Build Up Models for Bioconcentration Factor [PDF]
Molecular Informatics, 2020 AbstractWe establish a QSPR analysis for the bioconcentration factor of 851 heterogeneous structural compounds. Linear models are proposed via two different approaches: i. the optimal descriptor method implemented in CORAL, and ii. multivariable linear regressions on the best molecular descriptors found with the Replacement Method on 44,216 structural ...

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.

Model approach for estimating potato pesticide bioconcentration factor [PDF]
Chemosphere, 2008 We presented a model that estimates the bioconcentration factor (BCF) of pesticides in potatoes supposing that the pesticide in the soil solution is absorbed by the potato by passive diffusion, following Fick's second law. The pesticides in the model are nonionic organic substances, traditionally used in potato crops that degrade in the soil according ...

Prediction of bioconcentration factors in fish and invertebrates using machine learning [PDF]
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. However, comparison of different models and the prediction of bioconcentration in invertebrates has not been previously evaluated.
