About Hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size) in the Toxic Release Inventory

The Toxic Release Inventory (TRI) tracks how much of each listed chemical U.S. industrial facilities release into the environment each year. EPA requires facilities in certain industry sectors that manufacture, process, or otherwise use TRI-listed chemicals above threshold amounts to report annually. In 2024, 770 facilities reported releasing hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size) to EPA's TRI program.

The primary release pathway is air emissions (23.4M lb), which includes both stack emissions from industrial processes and fugitive emissions from equipment leaks, evaporation, and other non-point sources.

TRI data represents reported releases, not measured environmental concentrations. A facility reporting large releases of hydrochloric acid (acid aerosols including mists, vapors, gas, fog, and other airborne forms of any particle size) is not necessarily causing harm at those levels — toxicity, exposure pathways, and local conditions all matter. Conversely, small reported amounts of highly toxic chemicals can pose greater risk than large amounts of less toxic ones. TRI is a transparency tool, not a risk assessment.

For health information about specific chemicals, the Agency for Toxic Substances and Disease Registry (ATSDR) publishes toxicological profiles, and EPA's Integrated Risk Information System (IRIS) provides reference doses and cancer classifications.
