Use of the Bioaccumulation Factor to Screen Chemicals for Bioaccumulation Potential

Environmental Toxicology and Chemistry, 2012
Abstract The fish bioconcentration factor (BCF), as calculated from controlled laboratory tests, is commonly used in chemical management programs to screen chemicals for bioaccumulation potential. The bioaccumulation factor (BAF), as calculated from field-caught fish, is more ecologically relevant because it accounts for dietary ...

Assessing Metal Bioaccumulation in Aquatic Environments: The Inverse Relationship Between Bioaccumulation Factors, Trophic Transfer Factors and Exposure Concentration

Aquatic Toxicology, 2007
Bioaccumulation potential in aquatic biota is typically expressed using ratios of chemical concentrations in organism tissue (typically whole body) relative to chemical exposure concentrations, such as bioconcentration factors (BCFs). Past reviews of metal BCFs for aquatic biota, which account for water-only exposures, have shown that BCFs are often ...

Mercury bioaccumulation factors and spurious correlations

Science of The Total Environment, 2014
While bioaccumulation factors (BAF) - the ratio of biota contaminant concentrations (Cbiota) to aqueous phase contaminant concentrations (Cw) - are useful in evaluating the accumulation of mercury (Hg) and other contaminants for various trophic levels in aquatic ecosystems, reduction of the underlying relationship between Cbiota and Cw to a single ...

Lead in edible mushroomsLevels and bioaccumulation factors

Journal of Hazardous Materials, 2009
Lead content was determined in 238 samples of 28 species of edible mushrooms collected from different sites in the province of Lugo (NW Spain) during 2005 and 2006. The hymenophore (H) and the rest of the fruiting body (RFB) were analysed separately. The analyses were carried out by an anodic stripping voltammetric technique using drop mercury as the ...

Evaluation of Two Methods for Prediction of Bioaccumulation Factors

Environmental Science & Technology, 2003
Two methods for deriving bioaccumulation factors (BAFs) used by the U.S. Environmental Protection Agency in development of water quality criteria were evaluated using polychlorinated biphenyl (PCB) data from the Hudson River and Green Bay ecosystems.

Assessing bioaccumulation with biomagnification factors from dietary bioaccumulation tests

Integrated Environmental Assessment and Management
Abstract Despite the fact that the UN Stockholm Convention on persistent organic pollutants specifically acknowledges that Arctic ecosystems and Indigenous communities are particularly at risk due to biomagnification of contaminants in traditional foods, the bioconcentration factor (BCF) of substances in fish remains the preferred metric

[Influencing Factors of Cadmium Bioaccumulation Factor in Crops].

Huan jing ke xue= Huanjing kexue, 2021
The Cd bioaccumulation factor (BCF) of crops is affected by many aspects. In order to clarify the differences in the Cd bioaccumulation factor characteristics of different crops under field conditions and the influence of soil properties, point-to-point samples of soil and crop grains were collected during crop harvesting on plots with varying ...

BIOACCUMULATION FACTORS FOR CHLORINATED BENZENES, CHLORINATED BUTADIENES AND HEXACHLOROETHANE

Environmental Toxicology and Chemistry, 1997
Abstract A field study was performed that measured bioaccumulation factors (BAFs) for chlorinated benzenes, chlorinated butadienes, and hexachloroethane in four species, Fundulus heteroclitus (mummichog), Callinectes sapidus (blue crabs), Brevoortia patronus (gulf menhaden), and Micropoganias undulatus (Atlantic croaker).
