TL;DR: This study suggested that the bioaccumulation of PFAs in D. magna is mainly controlled by their partition between organisms and water; further research should be conducted to study the intrinsic mechanisms, especially the roles of protein and lipid in organisms.

TL;DR: Measured bioaccumulation of the hydrophilic chemical BP-4 was much higher than predicted by Kow-based bioconcentration models, which would lead to a marked underestimation of actual risk, and patterns of uptake found for BP-3 and OD-PABA suggest biotransformation ability of mussels for these two chemicals.

TL;DR: Oyster soft tissue, shell and sediments were analyzed for Cd, Cr, Cu, Fe, Mn, Pb, and Zn, suggesting a good discrimination against these metals by oysters.
Abstract: Oysters and sediment have been collected from most major US Gulf of Mexico bays and estuaries each year since 1986. Selected samples of oyster soft tissue, shell and sediments were analyzed for Cd, Cr, Cu, Fe, Mn, Pb, and Zn for this study. Concentrations varied considerably from place to place but ratios of metals remained relatively constant. Cu and Zn are greatly enriched in oyster tissues, which is related to their physiological function. Cd is enriched in oyster shell because of the easy substitution between Cd and Ca. The concentrations of Pb and Cr in oysters are significantly lower than that in sediment, suggesting a good discrimination against these metals by oysters. Metal variations are a result of both nature and human activity.

TL;DR: The potential of TNT to accumulate in aquatic organisms was assessed by determining bioconcentration factors for TNT and TNT biotransformation products using two benthic invertebrates and determining the bioaccumulation factor due to TNT exposure via feeding for channel catfish.
