Occupational Safety and Health Administration (OSHA) Carcinogens Air Releases
Air Releases
Some chemicals that are reportable to the TRI Program are included on OSHA’s list of carcinogens. EPA refers to these chemicals as TRI OSHA carcinogens. These chemicals are either known or believed to cause cancer in humans. A list of the TRI carcinogens can be found in the TRI basis of OSHA carcinogens document (pdf). This graph shows the 10-year trend in air releases of TRI OSHA carcinogens.
Note: For comparability, trend graphs include only those chemicals that were reportable to TRI for all years presented.
From 2011 to 2020:
- Air releases of these carcinogens decreased by 9%.
- Air releases of many OSHA carcinogens decreased, with reductions in most sectors. However, decreases were partially offset by increases in releases of styrene from the plastics and rubber products manufacturing sector and the transportation equipment manufacturing sector.
- In 2020, air releases of OSHA carcinogens consisted primarily of styrene (47% of the air releases of all OSHA carcinogens), acetaldehyde (13%) and formaldehyde (8%).
