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.
The Data Commons is a project of the Healthy Building Network (HBN) 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 and analyses 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 over 40 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 over 30 restricted substance lists. To learn more, check out the Pharos system description, starting on page 20.
Exempt & Positive lists - Listings of chemicals that have been exempted from regulatory actions (such as EPA VOC exemptions) or are preferable for use for certain applications based upon an assessment of lower hazard (such as the EPA SCIL list). Beware, these lists generally have constraints - exemptions of preferences based on a limited set of health endpoints or for limited uses
List Screening - The Data Commons is an approved GreenScreen Automator assessing all chemicals in the database against the GreenScreen List Translator to generate LT scores identifying known chemicals of high concern.
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 provides access to all GreenScreen assessments published for public use.
Identification - Over 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.
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.
