Beryllium (CAS 7440-41-7) 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 US DOE NNSA/NFO NEVADA NATIONAL SECURITY SITE in NV at 118.9K 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 Beryllium in the EPA TRI? ▼
Beryllium (CAS Number: 7440-41-7) 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. 26 facilities in the United States report releasing this chemical to the EPA.
How much Beryllium is disclosed in U.S. TRI filings? ▼
U.S. facilities have reported a total of 302.1K lbs of Beryllium releases to the EPA Toxic Release Inventory across 26 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 Beryllium? ▼
Beryllium 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 Beryllium? ▼
US Doe Nnsa/nfo Nevada National Security Site in NV reports the largest disclosed release of Beryllium in this dataset, at 118.9K lbs. Most reporting facilities for this chemical fall under hazardous waste. Release data is self-reported annually to the EPA under the TRI program. View the full list of 26 facilities on this page.
What is the CAS number for Beryllium? ▼
The CAS (Chemical Abstracts Service) Registry Number for Beryllium is 7440-41-7. CAS numbers are unique numerical identifiers assigned to every chemical substance described in the open scientific literature. This identifier is used to search scientific databases and regulatory filings.

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.
