Tetrabromobisphenol A

Tetrabromobisphenol A (CAS 79-94-7) is a chemical tracked by the EPA Toxics Release Inventory (TRI) program under Section 313 of the Emergency Planning and Community Right-to-Know Act. The TRI requires industrial facilities above specified threshold quantities to disclose annual manufacturing, processing, and otherwise-used volumes, along with quantities released to air, water, land, and off-site transfers.

Across the United States, 87 facilities have filed TRI Form R disclosures for Tetrabromobisphenol A, with a cumulative reported release volume of 879.7K lbs. The chemical is not flagged as a carcinogen in the TRI classification set. It is also listed as a persistent, bioaccumulative, and toxic (PBT) substance, a category subject to lower reporting thresholds and elevated regulatory concern. The largest individual disclosure in the current dataset comes from ALBEMARLE CORP SOUTH PLANT in AR at 499.9K lbs.

TRI volumes are self-reported estimates, not measured stack emissions, and each pound counts equally regardless of chemical toxicity, so total pounds should not be equated with total risk. Inclusion of a chemical or facility in the TRI does not itself establish a health hazard; it documents the public right-to-know record. Consult EPA's IRIS (Integrated Risk Information System) and the Agency for Toxic Substances and Disease Registry for health-effect summaries.
