View saved records

Vanadium Compounds (EPA TRI Category Code N770) 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 largest individual disclosure in the current dataset comes from NEVADA GOLD MINES LLC - GOLDSTRIKE MINES INC in NV at 11.9M 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 Vanadium Compounds in the EPA TRI? ▼
Vanadium Compounds (EPA TRI Category Code: N770) is a chemical tracked by the EPA Toxic Release Inventory (TRI) program. It is not marked as a carcinogen in the TRI classification set. 485 facilities in the United States report releasing this chemical to the EPA.
How much Vanadium Compounds is disclosed in U.S. TRI filings? ▼
U.S. facilities have reported a total of 142.2M lbs of Vanadium Compounds releases to the EPA Toxic Release Inventory across 485 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 Vanadium Compounds? ▼
Vanadium Compounds is not marked as a carcinogen in the TRI classification set. 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 Vanadium Compounds? ▼
Nevada Gold Mines LLC - Goldstrike Mines Inc in NV reports the largest disclosed release of Vanadium Compounds in this dataset, at 11.9M lbs. Most reporting facilities for this chemical fall under electric utilities. Release data is self-reported annually to the EPA under the TRI program. View the full list of 485 facilities on this page.
Why is Vanadium Compounds listed under code N770 instead of a CAS number? ▼
N770 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, "Vanadium 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

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.
