Correlation between the bioconcentration potential of organic environmental chemicals in humans and their n-octanol/water partition coefficients. [PDF]

, 1987
A quantitative relationship was found to exist between the lipophilicity (n-octanol/water partition coefficient) of pentachlorophenol, dieldrin, hexachlorobenzene, 2,3,7,8-tetrachlorodibenzo-p-dioxin, Σ DDT, polychlorinated biphenyls, &alpha ...

Prediction model for mercury transfer from soil to corn grain and its cross-species extrapolation

Journal of Integrative Agriculture, 2016
In this study the transfer characteristics of mercury (Hg) from a wide range of Chinese soils to corn grain (cultivar Zhengdan 958) were investigated. Prediction models were developed for determining the Hg bioconcentration factor (BCF) of Zhengdan 958 ...

Stoichiometric mismatches between Australian showy mistletoes and their hosts: You are what you assimilate

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract Ecological stoichiometry emphasizes that mismatches between the elemental composition of organisms and their resources can shape ecological interactions, evolutionary trajectories, and nutrient cycling. For hemiparasitic plants such as mistletoes, which draw water and nutrients from hosts while maintaining their own photosynthesis, such ...

Bioconcentration of octachlorodibenzo-p-dioxin (OCDD) in fish. [PDF]

, 1992
The most convincing argument against the hypothesis that persistent superlipophilic chemicals with log KOW >6, such as OCDD are bioconcentrated - if at all - to a low extent is that in all these bioconcentration experiments, except of 2,3,7,8-TCDD ...

Intercropping minimally influences differences in per- and polyfluoroalkyl substance (PFAS) uptake among three agricultural crops

Journal of Agriculture and Food Research
The widespread presence of per- and polyfluoroalkyl substances (PFAS) in agroecosystems challenges safe and profitable food production. To contribute to the broader understanding of crop-specific PFAS uptake, we cultivated lettuce (Lactuca sativa L ...

Half-lives and bioconcentration of lindane (gamma-HCH) in different fish species and relationship with their lipid content [PDF]

, 1997
In this investigation it is demonstrated that the half-lives of the insecticide lindane (gamma-HCH) in mussels and different fish species are dependent on their lipid content. It is found that the bioconcentration factors on a wet weight basis (BCF-w) of

Bioconcentration and biotransformation of organophosphorus flame retardants (PFRs) in common carp (Cyprinus carpio)

Environment International, 2019
Understanding the bioaccumulation and biotransformation of xenobiotic compounds is critical for evaluating their fate and potential toxicity in vivo. In the present study, the tissue specific accumulation and depuration of seven organophosphorus flame ...

Update of the risk assessment on emerging and novel brominated flame retardants in food

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on Emerging and Novel brominated flame retardants (BFRs) in food. Since the previous Opinion, further information was collected for a total of 27 BFRs. The CONTAM Panel concluded that TDBPP, DBPNG and TBNPA are considered genotoxic and carcinogenic.
