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 ...

The Assessment of Bioaccumulation

Chemosphere, 1994
Bioaccumulation and biomagnification of chemicals in biota may be a prerequisite for adverse effects in individuals, species, and ecosystems. From disastrous events posed by xenobiotic chemicals, e.g. PCBs, Dioxins, DDT etc. it must be concluded retrospectively that such impacts cannot be avoided and predicted sufficiently with existing hazard and risk

Bioaccumulation and Biomonitoring

, 2016
Bioaccumulation is defined as the increase of contaminant concentrations in aquatic organisms following uptake from the ambient environmental medium. Different sources of exposure contribute to contaminant bioaccumulation. Toxicokinetic parameters are critical in the bioaccumulation processes, including the dissolved uptake rate constant, dietary ...

Bioaccumulation of Perfluorochemicals in Pacific Oyster Under Different Salinity Gradients

Environmental Science & Technology, 2010
Despite the reports of widespread occurrence of perfluorinated compounds (PFCs) in estuarine and coastal waters and open seas, little is known on the effect of salinity on bioaccumulation.

Bioaccumulation of mercury and methylmercury

Water, Air, & Soil Pollution, 1995
The factors controlling the accumulation of mercury in fish are poorly understood. The oil invoked lipid solubility of MMHg is an inadequate explanation because inorganic Hg complexes, which are not bioaccumulated, are as lipid soluble as their MMHg analogs and, unlike other hydrophobic compounds, MMHg in fish resides in protein rather than fat tissue.

Bioaccumulation of marine pollutants

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1979
Abstract Bioaccumulation of pollutants can occur from sea water, from suspended particles, from sediments and through food chains. The rate at which accumulation occurs in an organism depends not only on the availability of the pollutant but also on a whole range of biological, chemical and environmental factors.

Bioaccumulation of Microcystins in Lettuce

Journal of Phycology, 2012
The contamination of lettuce (Lactuca sativa L.) by water‐borne crude extracts of the cyanobacterium microcystin‐producing Microcystis aeruginosa (Kützing) Kützing was investigated. The aim of the study was to determine whether bioaccumulation of microcystins occurs in lettuce foliar tissue when sprayed with solutions containing microcystins at ...

Bioaccumulation of nickel by algae

Environmental Science & Technology, 1984
Six strains of algae and one Euglena sp. were tested for their ability to bioaccumulate nickel. Radioactive /sup 63/Ni was used together with a microplate technique to determine the conditions for nickel removal by axenic cultures of cyanobacteria, green algae, and one euglenoid.

Plutonium bioaccumulation in seabirds

Journal of Environmental Radioactivity, 2011
The aim of the paper was plutonium (²³⁸Pu and ²³⁹⁺²⁴⁰Pu) determination in seabirds, permanently or temporarily living in northern Poland at the Baltic Sea coast. Together 11 marine birds species were examined: 3 species permanently residing in the southern Baltic, 4 species of wintering birds and 3 species of migrating birds.

Bioaccumulation processes in ecosystems

Experientia, 1992
The fate of environmental pollutants--the various isotopes of elements, and inorganic or organic compounds--is a fundamental aspect of ecology and ecotoxicology, and bioaccumulation is a phenomenon often discussed in this context. Human activities have drastically altered natural concentrations of many substances in the environment and added numerous ...
