Implications of U.S. Chemicals Policy DATA GAP SAFETY GAP (Information) (Accountability) TECHNOLOGY GAP (Capacity)
Data Gap: Business and Consumer Choice Necessary Information: Current U.S. market: Function Price Performance Hazards
Data Gap: State Governments’ Ability to Prioritize Risks Necessary Information: Available Information: Identity Sales volume Uses Hazards 4
Implications of U.S. Chemicals Policy DATA GAP SAFETY GAP (Information) (Accountability) TECHNOLOGY GAP (Capacity)
Safety Gap: TSCA’s “Catch 22” Definitive evidence of cause-and-effect Balance of the evidence Reasonable grounds for concern Scientific suspicion of risk Standard of evidence required for regulation Degree of certainty possible based on information currently available to EPA
Implications of U.S. Chemicals Policy DATA GAP SAFETY GAP (Information) (Accountability) TECHNOLOGY GAP (Capacity)
Technology Gap: Intellectual and technical capacity to support green chemistry Chemistry education lacks Toxicology Exposure Principles of green chemistry Producers lack Metrics for continuous improvement Assistance with commercialization
Chemicals Policy Stakeholders Producers Business Green Chemists Local Governments Consumers Chemicals Policy Stakeholders Environmental Justice Environmental Groups Public Health Labor
Global Chemical Production Growing 3% per year Doubling every 25 years
European Union Affecting Global Change REACH: Registration, Evaluation, Authorization, and Restriction of Chemicals Data generation and disclosure to government, public and through supply chains Management of chemicals of concern Global effects: applies equally to European and foreign producers and importers 11
REACH vs. TSCA Data disclosure for 30,000 chemicals Reversal of burden of proof: “no data, no market” Level playing field for new and existing chemicals Public access to information Two-way communication in supply chain Substances in products Authorization of substances of high concern
Policy Drivers of Green Chemistry EU: REACH State & Federal Legislation Biomonitoring Data Expanding Global Production Ecosystem Harm Policy Drivers of Green Chemistry Regrettable Substitutions Product Safety Product & Hazardous Waste Occupational Disease

Total PBDE levels in Swedish women's breast milk fell about 30 percent between 1997 and 2000, from a high of about 4 ng/g of milk fat, to 2.79 ng/g fat.23 Sweden is the only nation with a comprehensive breast milk monitoring program, so it has been difficult to track PBDE concentration trends elsewhere. However, in regions where bans and restrictions have not been established, available studies are showing that PBDE concentrations in breast milk have risen far past Sweden's 1997 peak of 4 ng/g milk fat. US levels higher than any other country. SF bay area levels 21x higher than Sweden’s 1997 peak Darnerud et al. 2002
