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.

A carcinogen flag, when present on other chemicals in this database, reflects an assessment from EPA, IARC, or the National Toxicology Program rather than a TRI-specific determination. The PBT (persistent, bioaccumulative, toxic) status above carries a lower TRI reporting threshold than most listed chemicals, reflecting elevated regulatory concern about long-term environmental buildup. 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.

Health Information

Persistent Bioaccumulative Toxicant (PBT): This chemical is classified as a PBT by the EPA. PBT chemicals are toxic, persist in the environment, and bioaccumulate in food chains. Because of these properties, even relatively small releases can pose a significant threat to human health and the environment over time.

Data comes from the EPA Toxic Release Inventory (TRI) program. Release quantities are self-reported by facilities and may represent estimates. The total shown aggregates reports across all facilities and reporting years.

PlainEnviro presents this data without advocacy framing. The presence of a chemical in the TRI database does not by itself indicate a health risk at current exposure levels. For health-related questions about specific chemical exposures, consult your local health agency or a toxicologist.
