Passive sampling in contaminated sediment assessment: Building consensus to improve decision‐making
Contaminated sediments pose an on‐going, pervasive, global challenge to environmental managers as sediments can reflect a legacy of pollution that can impair the beneficial uses of water bodies. A formidable challenge in assessing the risks of contaminated sediments has been elucidation and measurement of contaminant bioavailability, expressed as the freely dissolved concentration (Cfree) in ...

Understanding bioavailability and toxicity of sediment‐associated contaminants by combining passive sampling with in vitro bioassays in an urban river catchment
Bioavailable and bioaccessible fractions of sediment‐associated contaminants are considered as better dose metrics for sediment‐quality assessment than total concentrations. The authors applied exhaustive solvent extraction and nondepletive equilibrium sampling techniques to sediment samples collected along the Brisbane River in South East Queensland, Australia, which range from pristine ...

Fate Of Polychlorinated Biphenyls In A Contaminated Lake Ecosystem: Combining Equilibrium Passive Sampling Of Sediment And Water With Total Concentration Measurements Of Biota
Equilibrium sampling devices (ESDs) can be applied to study and monitor the exposure and fate of hydrophobic organic chemicals (HOCs) on a thermodynamic basis. ESDs can be used to determine freely dissolved concentrations and chemical activity ratios, and to predict equilibrium partitioning concentrations of HOCs in biota lipids. Our aim was to assess the equilibrium status of polychlorinated ...
