Assessment of bioconcentration and secondary poisoning of surfactants

Chemosphere, 2003
The relevance of the bioconcentration behaviour of surfactants for the secondary poisoning assessment and for the risk characterisation in the bird and mammalian food chain has been investigated. The approach used is described in the recently revised EU Technical Guidance Document for the Risk Assessment of Substances.

Bioconcentration and elimination of avermectin B1 in sturgeon

Environmental Toxicology and Chemistry, 2005
Abstract The bioconcentration and elimination of avermectin B1 in sturgeon muscle were investigated with high-performance liquid chromatography. Mean concentrations of 0.2 and 1 ng·ml−1 in water were maintained for a 22-d exposure period. The concentrations of avermectin B1α in muscle tissues reached steady state within 14 to 18 d.

Bioconcentration of tetrachlorobenzene in marine algae

Chinese Journal of Oceanology and Limnology, 1997
Bioconcentration of tetrachlorobenzene (TeCB) inChlorella marine, Nannochloropsis oculata, Pyramidomonas sp.,Platymonas subcordiformis, andPhaeodactylum tricornutum; and toxicity of TeCB to the marine algae were tested. Values of bioconcentration potential parameters, including uptake rate constantk1, elimination rate constantk2 and bioconcentration ...

Bioconcentration of Dioxins and Furans in Vegetation

Water, Air, and Soil Pollution, 2006
Information sources for bioconcentration factors (BCFs) from the existing technical literature include models based on K ow and/or regulatory agency guidance from agencies such as USEPA. Since magnitude assignments of BCFs influence the degree of conservativeness implicit in risk assessments, the BCF magnitudes for a contaminated site ...

Bioconcentration factors and lipid solubility

Environmental Science & Technology, 1991
The log-log relationship between bioconcentration and hydrophobicity breaks down for several medium and high molecular weight solutes that bioconcentrate either to a small extent or not at all. Much of the failure is attributed to the relatively low solubility of these compounds in lipid.
