Benzo[g,h,i]perylene

Benzo[g,h,i]perylene (CAS 191-24-2) 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, 1,323 facilities have filed TRI Form R disclosures for Benzo[g,h,i]perylene, with a cumulative reported release volume of 289.7K 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 CHEMICAL WASTE MANAGEMENT INC in CA at 37.7K 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.
