1. Bioavailability in the aquatic environment can be defined as the external availability of a chemical to an organism. The availability of sediment-sorbed chemicals to organisms is a particularly important aspect of this phenomena. 2. Various experiments described in the literature, such as toxicity and accumulation experiments, have investigated the influence of suspended sediment in the aqueous phase on bioavailability. 3. The bioavailability of a chemical appears to be influenced by the chemical, the sediment, and the organism being examined. Thus, describing "the bioavailability" of a chemical in the aquatic environment is not a simple process.

UI	MeSH Term	Description	Entries
D004064	Digestive System	A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).	Ailmentary System,Alimentary System
D005880	Gills	Paired respiratory organs of fishes and some amphibians that are analogous to lungs. They are richly supplied with blood vessels by which oxygen and carbon dioxide are exchanged directly with the environment.	Gill
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001682	Biological Availability	The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action.
