Metal Fluxes from Porewaters and Labile Sediment Phases for Predicting Metal Exposure and Bioaccumulation in Benthic Invertebrates.
The use of diffusive gradients in thin films (DGT) for predicting metal bioavailability was investigated by exposing the bivalve Tellina deltoidalis to an identical series of metal-contaminated sediments deployed simultaneously in the field and laboratory. To understand the differences in metal exposure occurring between laboratory- and field-based bioassays, we investigated changes in metal fl...
متن کاملMetal bioaccumulation in Persian sturgeon after sublethal exposure
Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscl...

1.1 This guide covers procedures for measuring the bioac,cumulation of sediment-associatid contaminants by infaunal .invertebrates. Marine, estuarine, and freshwater sediments are a major sink for chemicals that sorb preferentially to particles, 'such as organic compounds with high octanol-waterpartitioning coefficients (KO,) (for example, polychlorinated ,biphenyls (PCBs) and dichlorodiphenylt...
