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.

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

Variability in fish bioconcentration factors: Influences of study design and consequences for regulation

Chemosphere, 2020
The fish bioconcentration factor (BCF) is an important aspect within bioaccumulation assessments. Several factors have been suggested to influence BCF values - including species, developmental stage, mixture exposure, and calculation method.

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.
