Plant uptake study : the hyperaccumulating and remediating potential of three plant species
… the mine site was used for the control bins. The bioconcentration factor (BCF), biological accumulation coefficient (BAC) and biological transfer coefficient (BTC) data obtained suggested the plants could be used for phytostabilization and phytoextraction of selenium, however the plants were not …

Bioprospecting of plants species with potential to uptake inorganic chemical species from gold mine tailings and acid mine drainage
… than other parts of the plant. Translocation factor (TF) reflected that Cortaderia selloana plant species has the potential to translocate all the chemical species from the roots to the shoots except Se. Cortaderia selloana showed bioconcentration factor greater than 1 for chemical species …

Development of Alternative Methods to Assess the Toxicity and Bioaccumulation Potential of Chemicals in the Aquatic Environment
… the whole body biotransformation rate and bioconcentration factor of chemicals in fish. As a consequence of this investigation, an insight into the main challenges and future perspectives for each of the methods evaluated was conducted to provide a foundation for future research. The last …

Development and Standardization of a Short-Term Assay for Evaluating Polluted Estuarine and Coastal Environments: The Medaka Embryo-Larval Assay
… embryos. In addition, it appears that if the bioconcentration factor (BCF) is well established for a chemical, it may be possible to extrapolate to an equivalent medium concentration for a given topical dose. The permeability data indicate that the toxicants penetrate into the eggs at levels …

Pharmaceuticals removal in soil following wastewater land application
… to trimethoprim while the calculated plant bioconcentration factor for trimethoprim was higher than carbamazepine. The results indicate that the mean accumulated amount in the grass samples are significantly (p<0.05) higher than the mean accumulated mass in the soil samples. The total mass …

Combining phytoremediation with bioenergy production; exploring options for sustainable remediation
… contaminants into its aboveground tissues (with bioconcentration factor and translocation factor ranging from 0.81 – 0.94), and this was enhanced significantly by the application of plant growth promoting bacteria, Bacillus aryabhattai (with bioconcetration and translocation factor > 1 for all …

Climate Change and Dissolved Organic Matter in Subarctic Lakes: Relevance to Methylmercury Bioavailability
One of the first steps of methylmercury (MeHg) bioaccumulation, uptake by phytoplankton, is regulated by dissolved organic matter (DOM). Methylmercury binds strongly with DOM, especially high-molecular weight (HMW) compounds containing reduced sulphur; this binding decreases MeHg bioavailability. …

Quantification of the bioccumulation potential of various chemical elements from coal fly ash using Brassia juncea and Spinacia oleracea L and its implication for phytoremediation of coal fly ash dumps
… human beings, hence phytoremediation is vital. Bioconcentration factor (BCF) was used to estimate the metal species accumulation ability of the plants from the FA, FA/soil mixtures, while translocation factor (TF) was used to assess the plant species potential for phytoremediation of coal fly …
