According to the EPA Toxics Release Inventory, Arsenic Compounds (EPA TRI Category Code N020) is disclosed by 230 Form R facilities totaling 1167.2M lbs of reported releases. The TRI extract marks this chemical with a carcinogen classification flag. TRI pounds are self-reported disclosure totals, not a measured public-health risk score.
Arsenic Compounds (EPA TRI Category Code N020) 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 NEVADA GOLD MINES LLC - GOLDSTRIKE MINES INC in NV at 820.3M 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.

Trend & Where It's Reported
Between 2019 and 2023, cumulative annual Arsenic Compounds releases across all reporting facilities decreased by 41% (193.5M lbs → 114.6M lbs). Year-to-year swings reflect facility openings/closures and reporting changes as much as underlying activity.
Reporting for Arsenic Compounds is highly concentrated: Nevada accounts for 96.7% of the reported total (9 facilities). Next: Alaska.
- Nevada 1129.0M lbs
- Alaska 20.1M lbs
- Utah 5.6M lbs
- South Carolina 3.1M lbs
- West Virginia 2.5M lbs
Reporting for Arsenic Compounds is highly concentrated by industry: Metal Mining facilities account for 98.7% of the reported total (15 facilities). Next: Primary Metals.
- Metal Mining 1152.2M lbs
- Primary Metals 7.0M lbs
- Electric Utilities 6.3M lbs

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.
