Independent Scientific Governance for Chemical Transparency
The Chemical Data Commons by Healthy Building Network delivers transparent hazard profiles through an independent editorial board of certified toxicologists, industrial hygienists, and environmental health researchers. Every chemical assessment aggregates verified regulatory listings, authoritative toxicological inventories, and independent peer-reviewed literature to evaluate health impacts across the entire material life cycle.
Core Authoritative Sources and Integration Tiers
| Source Tier | Primary Repositories | Verification Cycle | Applied Hazard Criteria |
|---|---|---|---|
| Tier 1: Regulatory Mandates | EU REACH Annex XIV/XVII, US EPA TSCA Work Plan, California Proposition 65 | Quarterly automated sync | Direct regulatory classification and ban thresholds |
| Tier 2: Global Health Agencies | IARC Monographs, WHO GHS Lists, US CDC NIOSH | Semi-annual manual audit | Standardized epidemiological and carcinogenic classifications |
| Tier 3: Specialized Inventories | Pharos Database, GreenScreen for Safer Chemicals, ChemFORWARD | Continuous integration | Comprehensive hazard trait matrices and functional substitute evaluations |
Editorial Review and Data Harmonization Protocol
- Step 1: Automated extraction and structural deduplication via standardized CAS Registry Numbers and EC/EINECS identifiers.
- Step 2: Cross-referencing raw endpoint records against GHS classification criteria across 22 distinct human health and ecotoxicity endpoints.
- Step 3: Multi-expert editorial validation resolving contradictory screening classifications and documenting data gaps.
- Step 4: Formal publication of reviewed profiles with persistent versioning timestamps and audit logs.
Handling Compound Mixtures and Data-Deficient Chemicals
When assessing complex polymer formulations or trade-secret additives where CAS Registry Numbers are withheld, the editorial board mandates structural analogue modeling and surrogate evaluation based on functional groups. Missing toxicology data is explicitly classified under strict 'Data Gap' parameters rather than designated as benign or low-hazard.
