About the Chemical Hazard Data Commons
The Chemical Hazard Data Commons provides resources to assess and compare human and environmental health hazards of different chemicals, plus tools to collaborate to find safer alternatives. The goal of this effort is to reduce the use of hazardous chemicals and improve the inherent safety of materials and products. Our mission and vision is further detailed in a series of whitepapers.
Who We Are
The Data Commons is a project of the Healthy Building Network, a nonprofit founded in 2000 to reduce the use of hazardous chemicals in building products as a means of improving human health and the environment. The Data Commons project is comprehensive, not limited to chemicals used in the building industry.
The Data Commons integrates the following data sources to show what is known about the hazards of chemicals and facilitate comparisons:
Hazard listings - Associations between chemicals and specific human and environmental health endpoints identified by governmental and professional authorities. Largely based on the Healthy Building Network's Pharos Chemical and Material Library. The Data Commons aggregates 45 authoritative hazard lists. We constantly monitor the sources to keep up to date. To learn more, check out the Pharos system description, starting on page 9.
Restricted substance lists - Listings of chemicals whose use is restricted and/or managed by regulatory or corporate policy or subject to voluntary program guidance. Data Commons hazard tables reference 29 restricted substance lists. To learn more, check out the Pharos system description, starting on page 20.
Hazard assessments - Toxicological assessments using the GreenScreen™ protocol that benchmarks the inherent hazards of chemicals across a broad range of health endpoints. The Data Commons contains a comprehensive list of all GreenScreen assessments published for public use.
Identification - Approximately 50,000 chemicals are listed in the Data Commons, searchable by over 150,000 CASRNs and synonyms utilizing the NIH PubChem database.
Physical properties - chemical formulas and some key physical data are drawn from the NIH PubChem database.
- Compound groups - the Data Commons is the home of the Chemical Class Population Project which creates structural or other definitions for the chemical compound groups referenced by authoritative hazard lists. We use those definitions to associate relevant CASRN with those groups to ensure comprehensive list screening.
The above data is summarized in the General Info tab for each chemical.
The Additional Resources tab for each chemical in the Data Commons provides direct links to that chemical in other databases providing further important information:
Release - Releases to air, water, and land in the US are available from the USEPA Toxic Release Inventory database for almost 500 chemicals.
Contamination - Information on contaminated sites and remediation efforts around the globe are available from the Pure Earth Toxic Sites Identification Program Global Database.
And more - Links to other sites with information on chemical manufacturing, uses, physical properties, toxicity, exposure, REACH registrations, and more. Links include PubChem, ChemIDPlus, OECD eChemPortal, ECHA, and Pharos.
We are just beginning to provide links to publications referencing specific chemicals, now available in the Literature tab for each chemical as well as the Library page.
FAQs and “?” icons will lead you to more descriptive information about the sources used and functions provided throughout the site.
The Data Commons is supported by the Forsythia Foundation, the Lisa & Douglas Goldman Fund, and the John Merck Fund.
