According to the EPA Toxics Release Inventory, Cyclohexane (CAS 110-82-7) is disclosed by 1,019 Form R facilities totaling 24.1M lbs of reported releases. TRI pounds are self-reported disclosure totals, not a measured public-health risk score.
Cyclohexane (CAS 110-82-7) 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.
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 KING RANCH GAS PLANT in TX at 1.8M 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
Cyclohexane: how the 24.1M lbs splits
24.1M lbs across all reported pathways
- Air Releases20.5M lbs84.8%
- Off-site Transfers2.9M lbs12.0%
- Land Disposal597.9K lbs2.5%
- Water Discharges164.4K lbs0.7%
Cyclohexane's 24.1M lbs Form-R total is AIR, with air releases making up 84.8% of the bar. Next segment: off-site transfers at 12.0%.
Trend & Where It's Reported
Between 2019 and 2023, cumulative annual Cyclohexane releases across all reporting facilities increased by 54% (4.1M lbs → 6.3M lbs). Year-to-year swings reflect facility openings/closures and reporting changes as much as underlying activity.
Reporting for Cyclohexane is concentrated: Texas accounts for 27.7% of the reported total (241 facilities). Next: Louisiana.
- Texas 6.7M lbs
- Louisiana 2.3M lbs
- Ohio 1.9M lbs
- Virginia 1.3M lbs
- Kentucky 1.1M lbs
Reporting for Cyclohexane is concentrated by industry: Chemicals facilities account for 36.0% of the reported total (240 facilities). Next: Food.

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.
