Welcome to the Pharmaceuticals in the Environment, Information for Assessing Risk website. This is designed to provide
available information for assessing risks to aquatic resources from drugs entering
waterways from both point and non-point sources.
Pharmaceuticals are often both very toxic and resistant to chemical treatment. They are frequently discharged from sewage treatment plants unaltered and enter aquatic environments at concentrations approximating well studied agricultural pesticides. However, relatively little is known about the risks posed to aquatic organisms. This website provides available information useful for assessing those risks.
For more about this project, please view the
project overview.
This site includes information on frequently prescribed drugs as well as most antibiotics
and lipid-lowering drugs. You can
search the database by:
- Chemical Abstract Service Registry Number
- Name of Contaminant
- Molecular Formula
- Pharmaceutical Type
Contents of the Database
The database provides information on prescribed amounts, levels detected in aquatic
environments, chemical structure, molecular weight, octanol-water partition coefficients,
water solubility, environmental persistence, general toxicity information and specific
toxicity levels to five groups of organisms (algae, mollusks, finfish, crustaceans,
and select terrestrial animals).
Toxicity to terrestrial animals is provided as a general comparison to a large body
of available toxicological literature. All of this information was obtained from
available scientific literature and is provided to assist identifying locations
where risks to aquatic organisms might occur.
Disclaimer
We do not imply that this is a comprehensive database. We may update the data
as new sources are identified. Please
contact us if you find errors in the data provided. Reasonable effort was
made to accurately describe source data, and all values were reviewed by a team of
scientists.
However, users are cautioned that some methods were not adequately described
in the source references. All users are advised to consult the original reference
before using these data.
