Daphnia need to be gut cleared too: The effect of exposure to and ingestion of metal-contaminated sediment on the gut clearance patterns in D. magna
The presence of sediment particles in the gut indicated that Daphnia magna used in whole-sediment bioassays ingest sediment. If gut contents are not removed prior to whole-body tissue-burden analysis, then the bioavailability of any sediment-associated contaminants (e.g. metals)

A simplified assessment of factors controlling phosphorus loading from oxygenated sediments in a very shallow eutrophic lake
Factors controlling the release of bioavailable soluble reactive phosphorus (SRP) from sediments in very shallow lakes are not fully understood. Our approach involved relatively simple measurements of four factors affecting the calculation of internal phosphorus load: the number

Relationship Between Sediment Phosphorus Release Rates and Characteristics of the Benthic Microbial Community in a Hypereutrophic Marsh
Cootes Paradise Marsh is a hypereutrophic coastal wetland of Lake Ontario that has received sewage from the town of Dundas, Ontario for over eight decades. As such, sediments are nutrient rich and phosphorus release from the sediments is substantial. Release rates of soluble
