Cadmium Compounds (EPA TRI Category Code N078) 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.

The carcinogen flag above reflects an assessment from EPA, the International Agency for Research on Cancer, or the National Toxicology Program, not a TRI-specific determination. The largest individual disclosure in the current dataset comes from BEFESA ZINC METAL LLC in NC at 2.4M 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 Cadmium Compounds in the EPA TRI?
Cadmium Compounds (EPA TRI Category Code: N078) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. The TRI extract marks it with a carcinogen classification flag based on EPA/IARC/NTP listings. 74 facilities in the United States report releasing this chemical to the EPA.
How much Cadmium Compounds is disclosed in U.S. TRI filings?
U.S. facilities have reported a total of 8.1M lbs of Cadmium Compounds releases to the EPA Toxic Release Inventory across 74 facilities. Release quantities are self-reported estimates covering air, water, land, and off-site transfers. They are disclosure totals, not toxicity-weighted harm scores.
How does EPA TRI classify Cadmium Compounds?
Cadmium Compounds carries a carcinogen classification flag in the TRI database (drawn from EPA, IARC, or NTP listings). TRI classification flags document inventory listing status; they are not a site-specific exposure or health diagnosis. For health-effect summaries see EPA IRIS and ATSDR toxicological profiles.
Which facilities disclose the most Cadmium Compounds?
Befesa Zinc Metal LLC in NC reports the largest disclosed release of Cadmium Compounds in this dataset, at 2.4M lbs. Most reporting facilities for this chemical fall under primary metals. Release data is self-reported annually to the EPA under the TRI program. View the full list of 74 facilities on this page.
Why is Cadmium Compounds listed under code N078 instead of a CAS number?
N078 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, "Cadmium Compounds" 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.
