Occupational Safety and Health Administration (OSHA) Carcinogens Air Releases
Among the chemicals that are reportable to the TRI Program, some are also included on OSHA’s list of carcinogens. EPA refers to these chemicals as TRI OSHA carcinogens. This graph shows the trend in the pounds of TRI-reported OSHA carcinogens released to air.
Note: For comparability, trend graphs include only those chemicals that were reportable to TRI for all years presented.
From 2007 to 2019:
- Releases of these carcinogens to air decreased by 38%.
- The long-term decreases in releases of OSHA carcinogens to air were driven by decreases in releases of many chemicals across multiple sectors. Almost every TRI-covered industry sector decreased its releases of carcinogens to air from 2007 to 2019.
- In 2019, releases of OSHA carcinogens to air consisted primarily of styrene (47% of the air releases of all OSHA carcinogens), acetaldehyde (12%) and formaldehyde (8%).
