According to the EPA Toxics Release Inventory, Butyraldehyde (CAS 123-72-8) is disclosed by 33 Form R facilities totaling 1.7M lbs of reported releases. TRI pounds are self-reported disclosure totals, not a measured public-health risk score.
Butyraldehyde (CAS 123-72-8) 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 SOLUTIA INC in MA at 449.1K 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.

Butyraldehyde's 1.7M lbs Form-R total is AIR, with air releases making up 74.2% of the bar. Next segment: off-site transfers at 14.0%.
Trend & Where It's Reported
Between 2019 and 2023, cumulative annual Butyraldehyde releases across all reporting facilities decreased by 43% (478.7K lbs → 274.6K lbs). Year-to-year swings reflect facility openings/closures and reporting changes as much as underlying activity.
Reporting for Butyraldehyde is dispersed: Texas accounts for 22.6% of the reported total (12 facilities). Next: North Carolina.
- Texas 395.3K lbs
- North Carolina 390.1K lbs
- Massachusetts 371.9K lbs
- Tennessee 295.1K lbs
- West Virginia 156.8K lbs

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.
