Contaminants Bioaccumulation and Biomagnification in a Short Trophic System: Phytoplankton, Zooplankton, Anchovy, Sardine (costas)
The main scientific goal of COSTAS project is to bring useful knowledge to the understanding of the conditions, which favor the accumulation and transfer of organic and metallic contaminants at the primary trophic levels (autotrophes and hetetrophes), and then within the food web of small pelagic fish (anchovy and sardine) in the Gulf of Lion, Western Mediterranean.
متن کاملBioconcentration, Bioaccumulation, and Biomagnification in Puget Sound Biota: Assessing the Ecological Risk of Chemical Contaminants in Puget Sound
The following piece is republished from the UWT Journal on the Environment, an electronic, peer-reviewed journal designed to provide students with a forum in which to publish and read primary and secondary research, reports on conferences and events, and ideas and opinions in the environmental sciences and studies. Tahoma West encourages submissions that deal with scientific and social matters....
متن کاملMercury bioaccumulation and biomagnification in Ozark stream ecosystems.
Crayfish (Orconectes spp.), Asian clam (Corbicula fluminea), northern hog sucker (hog sucker; Hypentelium nigricans), and smallmouth bass (smallmouth; Micropterus dolomieu) from streams in southeastern Missouri (USA) were analyzed for total mercury (HgT) and for stable isotopes of carbon (δ¹³C), nitrogen (δ¹⁵N), and sulfur (δ³⁴S) to discern Hg transfer pathways. HgT concentrations were generall...
متن کاملMathematical relationships between metrics of chemical bioaccumulation in fish.
Five widely used metrics of bioaccumulation in fish are defined and discussed, namely the octanol-water partition coefficient (KOW ), bioconcentration factor (BCF), bioaccumulation factor (BAF), biomagnification factor (BMF), and trophic magnification factor (TMF). Algebraic relationships between these metrics are developed and discussed using conventional expressions for chemical uptake from w...
متن کاملIn Vivo Biotransformation Rates of Organic Chemicals in Fish: Relationship with Bioconcentration and Biomagnification Factors.
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 development and ...
