The Bioconcentration of Zinc by Gammarus pulex (L.) and the Application of a Kinetic Model to Determine Bioconcentration Factors

Water Research, 1993
Abstract The bioconcentration, and subsequent elimination, of zinc by the freshwater amphipod Gammarus pulex (L.) were determined experimentally in the laboratory at five zinc exposure concentrations (0.41–2.02 mg/l). A first-order kinetic model, modified for naturally occurring trace chemicals, was then used to calculate uptake ( K 1 ) and ...

Bioconcentration of Bromo- and Chlorobenzenes by Fish (Gambusia affinis)

Water Research, 1997
Bioconcentration factors, uptake rate constants (k1), and clearance rate constants (k2) were determined for bromo- and chlorobenzenes with the mosquito fish (Gambusia affinis).

The Importance of Bioconcentration Into the Pelagic Food Web Base for Methylmercury Biomagnification: A Meta-Analysis

Science of the Total Environment, 2019
Methylmercury (MeHg) transfer from water into the base of the food web (bioconcentration) and subsequent biomagnification in the aquatic food web leads to most of the MeHg in fish.

ESTIMATING AND TESTING BIOCONCENTRATION FACTORS

Environmental Toxicology and Chemistry, 2000
Abstract Bioconcentration factors (BCFs) are commonly calculated to represent the equilibrium concentration of a substance in an organism relative to environmental concentrations of the same substance. The BCF is derived from parameters estimated in uptake and elimination experiments and is presented as a single value without error ...

Bioconcentration study of Xinjunan in zebrafish

Environmental Monitoring and Assessment, 2011
An experiment was carried out to determine the acute toxicity and bioconcentration factor of Xinjunan in zebrafish under semi-static test method. The result of the 96-h LC(50) values (0.31 mg/L), at 95% confidence limit, revealed that Xinjunan was highly toxic.

Amiodarone bioconcentration and suppression of metamorphosis in Xenopus

Aquatic Toxicology, 2020
Trace concentrations of a number of pharmaceutically active compounds have been detected in the aquatic environment in many countries, where they are thought to have the potential to exert adverse effects on non-target organisms. Amiodarone (AMD) is one such high-risk compound commonly used in general hospitals.

Surfactant bioconcentration - a critical review

Chemosphere, 1994
Bioconcentration data for surfactants have been collected and critically reviewed. Twenty-two references report whole body bioconcentration data. Most of these data are inappropriate to quantitatively describe the bioconcentration of surfactants because the most frequently used analytical method, LSC without prior chromatographic separation of ...
