SRC’s mission is to help keep America safe and strong by protecting its people, environment and way of life. We will do this by focusing on our customers’ needs through the innovative application of science, technology and information to solve problems of national significance. As a not-for-profit, research and development company that develops unique, creative solutions for nationally significant challenges in defense, environmental and intelligence, we’re committed to redefining possible®. Our relentless determination to solve the “impossible” with bright minds, fresh thinking and fearless innovation, is grounded in more than 50 years of experience. We seek and welcome the toughest problems — the ones most critical to our national welfare, the ones where compromise is not an option. By constantly reinvesting in our people and our technologies, we never ask you to accept just what’s possible. We help you go beyond it.  



ChemSpider is a free chemical structure database providing fast text and structure search access to over 26 million structures from hundreds of data sources. 


ECOTOX Database

The ECOTOXicology database (ECOTOX) is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX was created and is maintained by the U.S.EPA, Office of Research and Development (ORD) , and the National Health and Environmental Effects Research Laboratory’s (NHEERL’s) Mid-Continent Ecology Division (MED). ECOTOX integrates three previously independent databases – AQUIRE, PHYTOTOX, and TERRETOX – into a unique system which includes toxicity data derived predominately from the peer-reviewed literature, for aquatic life, terrestrial plants, and terrestrial wildlife, respectively. 


US EPA-OPP (United States Environment Protection Agency, Office of Pesticide Programs) 

The National Pesticide Information Retrieval System (NPIRS®) is a collection of pesticide-related databases available by subscription. NPIRS® is under the administration of the Center for Environmental and Regulatory Information Systems, CERIS, at Purdue University in West Lafayette, Indiana.


HSDB – Hazardous Substances Data Bank

Databases on toxicology, hazardous chemicals, environmental health, and toxic releases. 


Distributed Structure-Searchable Toxicity (DSSTox)

Database Network is a project of EPA’s Computational Toxicology Program, helping to build a public data foundation for improved structure-activity and predictive toxicology capabilities. The DSSTox website provides a public forum for publishing downloadable, standardized chemical structure files associated with toxicity data.


QSAR and Modeling Society

The QSAR and Modeling Society provides several resources about databases, software, supercomputing centers, web services. 



The FOOTPRINT Pesticide Properties Database (FOOTPRINT PPDB) is a comprehensive relational database of pesticide physicochemical and ecotoxicological data. The database has been developed by the Agriculture & Environment Research Unit (AERU) at the University of Hertfordshire, as part of the EU-funded FOOTPRINT project. The new database is a revised and greatly expanded version of the database that originally accompanied the EMA (Environmental Management for Agriculture) software used in the UK. The database will be integrated in the FOOTPRINT pesticide risk assessment and management tools (the ‘FOOT tools’).



The RCSB PDB provides a variety of tools and resources for studying the structures of biological macromolecules and their relationships to sequence, function, and disease. The RCSB is a member of the wwPDB whose mission is to ensure that the PDB archive remains an international resource with uniform data. This site offers tools for browsing, searching, and reporting that utilize the data resulting from ongoing efforts to create a more consistent and comprehensive archive.


Enhanced NCI Database

 A web service to the open NCI database compounds (>250,000 structures) with different kinds of output features and links to other services for continued processing 


Joint Institute for Food Safety and Applied Nutrition 

© 2006 Joint Institute for Food Safety and Applied Nutrition, contains several tools to assess risk for food, databases, research tools.
