Carcinogen PBT

CAS Number: 57-74-9

Chlordane (CAS 57-74-9) 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, 27 facilities have filed TRI Form R disclosures for Chlordane, with a cumulative reported release volume of 14.1K lbs. The chemical carries a carcinogen classification in the TRI database, based on assessments from EPA, IARC, or the National Toxicology Program. 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 US ECOLOGY NEVADA INC. in NV at 5.6K 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.

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.

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.
