Journal ArticleDOI
A review of bioconcentration factor (BCF) and bioaccumulation factor (BAF) assessments for organic chemicals in aquatic organisms
TL;DR: The status of bioaccumulation assessment is important in the scientific evaluation of risks that chemicals may pose to humans and the environment and is a current focus of regulatory effort as discussed by the authors.
Journal ArticleDOI
Food Web-Specific Biomagnification of Persistent Organic Pollutants
Barry C. Kelly,Michael G. Ikonomou,Michael G. Ikonomou,Joel D. Blair,Joel D. Blair,Anne E. Morin,Anne E. Morin,Frank A. P. C. Gobas,Frank A. P. C. Gobas +8 more
TL;DR: It is shown that poorly metabolizable, moderately hydrophobic substances with a KOW between 100 and 100,000 can biomagnify to a high degree in food webs containing air-breathing animals (including humans) because of their high octanol-air partition coefficient (KOA) and corresponding low rate of respiratory elimination to air.
Journal ArticleDOI
A food web bioaccumulation model for organic chemicals in aquatic ecosystems.
TL;DR: The new model is able to provide better estimates of bioaccumulation factors in comparison to the previous food web bioaccUMulation model while the model input requirements remain largely unchanged.
Journal ArticleDOI
Perfluoroalkyl Contaminants in an Arctic Marine Food Web: Trophic Magnification and Wildlife Exposure
Barry C. Kelly,Michael G. Ikonomou,Joel D. Blair,Blair Surridge,Dale Hoover,Richard Grace,Frank A. P. C. Gobas +6 more
TL;DR: The anticipated phase-partitioning of these proteinophilic substances, represented by their protein-water (KPW) and protein-air (KPA) partition coefficients, likely results in efficient respiratory elimination in water-respiring organisms but very slow elimination and biomagnification in air-breathing animals.
Journal ArticleDOI
Trophic magnification factors: Considerations of ecology, ecosystems, and study design
Katrine Borgå,Karen A. Kidd,Derek C. G. Muir,Olof Berglund,Jason M. Conder,Frank A. P. C. Gobas,John R. Kucklick,Olaf Malm,David E. Powell +8 more
TL;DR: Empirical TMFs are likely to be useful for understanding the food web biomagnification potential of chemicals, but may be less useful in species- and site-specific risk assessments, where the goal is to predict absolute contaminant concentrations in organisms in relation to threshold levels.
