Aquatic toxicology is the study of the effects of chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems. This field of study includes freshwater, marine water and sediment environments. Common tests include standardized acute and chronic toxicity tests lasting 24–96 hours to 7 days or more. Aquatic toxicology tests toxicity tests are used to provide qualitative and quantitative data on adverse effects on aquatic organisms from a toxicant. Toxicity tests can be used to assess the potential for damage to an aquatic environment and provide a database that can be used to assess the risk associated with in a situation for a specific toxicant.
