Specific Substances: Cumene
Nomination Date: 04/09/1996
Rationale: Large segments of the population are exposed to cumene due to its high level of production and its presence in fuels. Approximately 18 million pounds of cumene are released into the environment annually. In 1988 the EPA estimated that about 3 million pounds of cumene were released from manufacturing and processing facilities and 15 millions pounds were released from vehicle emissions. Numerous short-term studies have been performed on cumene, but it has not been tested for chronic toxicity.
