Chemical Effects in Biological Systems

The CEBS database houses data of interest to environmental health scientists. CEBS is a public resource, and has received depositions of data from academic, industrial and governmental laboratories. CEBS is designed to display data in the context of biology and study design, and to permit data integration across studies for novel meta analysis.


Free database of chemical structures of small organic molecules and information on their biological activities. Linked with NIH PubMed/Entrez information retrieval system.


Aggregated Computational Toxicology Resource. produced by the U.S. Environmental Protection Agency, National Center for Computational Toxicology. More than 200 sources of publicly available data on environmental chemicals have been brought together and made searchable by chemical name and other identifiers, and by chemical structure. Data includes chemical structure, physico-chemical values, in vitro assay data, exposure data, and in vivo toxicology data. Chemicals include, but are not limited to, high and medium production volume industrial chemicals, pesticides (active and inert ingredients), and potential ground and drinking water contaminants.
