According to the EPA Toxics Release Inventory, Acetaldehyde (CAS 75-07-0) is disclosed by 510 Form R facilities totaling 41.3M 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.
Acetaldehyde (CAS 75-07-0) 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 INTERNATIONAL PAPER BOGALUSA MILL in LA at 832.5K 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.
AIR pathway mix
Acetaldehyde: how the 41.3M lbs splits
41.3M lbs across all reported pathways
- Air Releases38.2M lbs92.4%
- Water Discharges1.6M lbs3.9%

Acetaldehyde's 41.3M lbs Form-R total is AIR, with air releases making up 92.4% of the bar. Next segment: water discharges at 3.9%.
Trend & Where It's Reported
Between 2019 and 2023, cumulative annual Acetaldehyde releases across all reporting facilities decreased by 10% (8.4M lbs → 7.6M lbs). Year-to-year swings reflect facility openings/closures and reporting changes as much as underlying activity.
Reporting for Acetaldehyde is dispersed: Iowa accounts for 9.1% of the reported total (46 facilities). Next: Alabama.
- Iowa 3.7M lbs
- Alabama 3.2M lbs
- Louisiana 3.2M lbs
- Georgia 2.9M lbs
- Texas 2.5M lbs
Reporting for Acetaldehyde is highly concentrated by industry: Paper facilities account for 50.2% of the reported total (106 facilities). Next: Chemicals.

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.
