EPA TRI Category Code: N575

Polybrominated Biphenyls (EPA TRI Category Code N575) 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, 2 facilities have filed TRI Form R disclosures for Polybrominated Biphenyls, with a cumulative reported release volume of 8.6K lbs. The chemical carries a carcinogen classification in the TRI database, based on assessments from EPA, IARC, or the National Toxicology Program. The largest individual disclosure in the current dataset comes from GERDAU LONG STEEL NORTH AMERICA - JACKSON MILL in TN at 8.6K 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.

Frequently Asked Questions

What is Polybrominated Biphenyls? ▼
Polybrominated Biphenyls (EPA TRI Category Code: N575) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. It is classified as a known or suspected carcinogen. 2 facilities in the United States report releasing this chemical to the EPA.
How much Polybrominated Biphenyls is released in the U.S.? ▼
U.S. facilities have reported a total of 8.6K lbs of Polybrominated Biphenyls releases to the EPA Toxic Release Inventory across 2 facilities. Release quantities are self-reported estimates. This includes releases to air, water, land, and off-site transfers.
Is Polybrominated Biphenyls harmful to health? ▼
Polybrominated Biphenyls is classified as a known or suspected carcinogen by the EPA, based on evaluations from IARC, NTP, or EPA itself. Health effects depend on exposure levels, duration, and route. For specific health questions, consult a toxicologist or your local health agency.
Which facilities release the most Polybrominated Biphenyls? ▼
The largest reported releasers of Polybrominated Biphenyls include facilities across multiple states. Release data is self-reported annually to the EPA under the TRI program. View the full list of 2 facilities on this page.
Why is Polybrominated Biphenyls listed under code N575 instead of a CAS number? ▼
N575 is an EPA TRI Category Code, not a CAS Registry Number. EPA assigns category codes (N-prefix and K-prefix) to chemical groups that share reporting requirements, for example, "Polybrominated Biphenyls" covers many distinct compounds aggregated for TRI reporting. Individual constituents may have their own CAS Registry Numbers (e.g., elemental Lead is CAS 7439-92-1), but the group is reported under the single TRI Category Code.

Health Information

Carcinogen Classification: This chemical is classified as a known or suspected carcinogen by the EPA under the Toxic Release Inventory program. This classification is based on evaluations by agencies including the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), and the EPA itself.

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.
