Bioconcentration Factors (BCF) of Silver in Wild Agaricus campestris
Bulletin of Environmental Contamination and Toxicology, 1995Silver is an element naturally occurring in small concentrations in different environmental sites. However, many anthropogenic sources of silver led to contamination of this element in soil surfaces, pastures, and coastal marine areas in different parts of the world.

The bioconcentration factor (BCF) is an important bioaccumulation hazard assessment metric in many regulatory contexts. Its assessment is required by the REACH regulation (Registration, Evaluation, Authorization and Restriction of Chemicals) and by CLP (Classification, Labeling and Packaging).

QSAR Study on Bioconcentration Factor (BCF) of Polyhalogented Biphenyls Using the PI Index
Bioorganic and Medicinal Chemistry, 2003Attempt has been made to estimate the accuracy, predictive power, and domain of application of the PI (Padmakar-Ivan) index for modeling bioconcentration factor (BCF) of polyhalogenated biphenyls. Relative potential of PI index is investigated by comparing the results obtained using this index with those obtained from Wiener (W) and Szeged (Sz) indices.

Bioaccumulation assessment is important in the scientific evaluation of risks that chemicals may pose to humans and the environment and is a current focus of regulatory effort. The status of bioaccumulation evaluations for organic chemicals in aquatic systems is reviewed to reduce uncertainty in bioaccumulation measurement, to provide quality data for ...

This study examined 42 mushroom samples and corresponding cultivated substrates. The radionuclide activity concentrations and bioconcentration factor (BCF) from substrate-to-mushroom were determined. The substrate activity concentrations were 59.1-727.5, 4.5-37.6, and 4.0-53.0 Bq/kg dw (dry weight) for 40 K, 226Ra, and 232Th, respectively.

The bioconcentration factor (BCF) is the ratio of the concentration of a chemical in an organism to the concentration in the surrounding environment at steady state. It is a valuable indicator of the bioaccumulation potential of a substance. BCF is an essential environmental property required for regulatory purposes within the Registration, Evaluation,

Bioconcentration Factor(BCF) of Perchlorate From Agricultural Products and Soils [PDF]
Korean Journal of Environmental Agriculture, 2013 BACKGROUND: Perchlorate() is an anion that is extremely water-soluble and environmentally stable. It mostly exists in the form of sodium perchlorate, ammonium perchlorate and potassium perchlorate which are used in rocket fuels, propellants, ignitable sources, air bag inflation systems and explosives.

Bioconcentration of Octachlorodibenzo-p-Dioxin (OCDD) in Fish
Chemosphere, 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 ...

Predictive regression-based models for bioconcentration factor (BCF) have been developed using mechanistically interpretable descriptors computed from open source tool PaDEL-Descriptor ( http://padel.nus.edu.sg/software/padeldescriptor/ ). A data set of 522 diverse chemicals has been used for this modeling study, and extended topochemical atom (ETA ...

Polychlorinated bornanes, the main components of Toxaphene, are bioconcentrated in aquatic organisms to a high extent. However, up to this time no bioconcentration tests with individual chlorinated bornanes in aquatic organisms have been performed. Therefore, the bioconcentration factors (BCFs) of seven selected persistent chlorinated bornane congeners
