Such a model is first applied to the bioaccumulation of a series of hypothetical, non-biotransforming chemicals with log K OW (octanol–water partition ratio) values of 4 to 8 in 10 g fish ranging in lipid contents to deduce wet-weight and lipid normalized concentrations, bioaccumulation and biomagnification factors. The sensitivity of Cited by: 5.   Among many other parameters, bioaccumulation of metals and organic chemicals has been measured in two benthic invertebrates (mussels (white furrow shell, Abra alba) and snails (common whelk, Buccinum undatum)) and fish (dab, Limanda limanda) sampled in and around the disposal site as well as in reference sites. These species were selected since they are abundant in the Cited by:

These BCFs can be considered high estimates of bioaccumulation, because of the use of total 14C-content of individual whole fish rather than the content of unmetabolized chemical in muscle.

Bioaccumulation of highly hydrophobic chemicals (log K OW > 8) from contaminated sediments by Lumbriculus variegatus has been studied for relatively few chemicals, and the measured and model predicted biota-sediment accumulation factors (BSAFs) can differ by orders of magnitude.

In vivo dietary bioaccumulation experiments for 85 hydrophobic organic substances were conducted to derive the in vivo gastrointestinal biotransformation rates, somatic biotransformation rates, bioconcentration factors (BCF), and biomagnification factors (BMF) for improving methods for bioaccumulation assessment and to develop an in vivo biotransformation rate database for QSAR Cited by: Bioaccumulation and Occurrence of Endocrine-Disrupting Chemicals (EDCs), Persistent Organic Pollutants (POPs), and Other Organic Compounds in Fish and Other Organisms Including Humans Harald J.

The data were interpreted using the fugacity modeling concept.

A mechanistic bioaccumulation model is compared to the measured data and used to illustrate the influence of growth and biotransformation rates on the by: Although laboratory testing and models regarding the assessment of bioaccumulation potentials of hydrophobic organic chemicals have been mostly developed with freshwater organisms, bioaccumulation in marine organisms is a significant concern in marine ecosystems (McGeer et Cited by: 1.

Bioaccumulation and biomagnification are two terms commonly used for metal toxicity. Bioaccumulation refers to how pollutants (metals) enter a food chain and relates to the accumulation of contaminants, in biological tissues by aquatic organisms, from sources such as water, food, and particles of suspended sediment (Wang and Fisher, ).

Biomagnification of hydrophobic organic compounds (HOCs) increases the eco-environmental risks they pose. Here, we gained mechanistic insights into biomagnification of deuterated polycyclic aromatic hydrocarbons (PAHs-d10) in zebrafish with carefully controlled water (ng L–1) by a passive dosing method and dietary exposures using pre-exposed Daphnia magna and fish by: 4.
