TL;DR: Despite the existence of several knowledge gaps, passive sampling presently is the best available technology for chemical monitoring of nonpolar organic compounds.

TL;DR: In this article, various scientific and regulatory aspects of bioaccumulation in aquatic systems and the relevant critical issues are discussed, as well as strategies for bioaccUMulation assessment still need to be harmonised for different regulations and groups of chemicals.

TL;DR: Various strategies for quantifiable transfer from environmental samples including water, sediment, and biota into bioassays using total extraction or polymer-based passive sampling combined with either solvent spiking or passive dosing are outlined.

TL;DR: In this article, the authors applied silicone coated glass jars for equilibrium sampling of seven indicator polychlorinated biphenyls (PCBs) in sediment samples from ten locations along the River Elbe to measure cfree of PCBs and their clip-sed.

TL;DR: The utility of passive dosing to control Cfree in routine chronic toxicity testing of HOCs is demonstrated and both chemical uptake from water or via food ingestion can be controlled, thus enabling the discrimination of different uptake routes in chronic toxicity studies.
