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 chemicals that are OSHA carcinogens released to air.
From 2007 to 2017:
- Air releases of these carcinogens decreased by 37%.
- The long-term decreases in air releases of OSHA carcinogens were driven mainly by decreases in releases of styrene to air from the plastics and rubber and transportation equipment industries.
- In 2017, air releases of OSHA carcinogens consisted primarily of styrene (43% of the air releases of all OSHA carcinogens), acetaldehyde (13%) and formaldehyde (8%).
