US EPA Finalizes Risk Evaluation for Flame Retardant TCEP
EPA Releases Final Risk Evaluation for TCEP: Unreasonable Risk to Human and Environmental Health
The United States Environmental Protection Agency (EPA) has published its final risk evaluation for tris(2-chloroethyl) phosphate (TCEP), a widely used chemical under the Toxic Substances Control Act. According to the evaluation, TCEP poses an unreasonable risk to human health and the environment.
What is TCEP?
TCEP is primarily used as a flame retardant and plasticizer and can be found in various products, including paints, coatings for aerospace and automotive applications, and construction materials. Historically, TCEP was used in fabrics, textiles, and foam seating. While domestic production of TCEP in the U.S. has dropped by 99% since 2014, the chemical is still imported as a component of various products.
Health Hazards Associated with TCEP
The EPA's risk evaluation highlights several health risks associated with TCEP. The chemical has been linked to severe health concerns, such as:
- Kidney cancer
- Damage to the nervous system and kidneys
- Reproductive harm, including risks to fertility
How TCEP Poses a Risk
TCEP poses a risk to workers, consumers, and the environment due to its ability to leach from the materials it’s mixed into. The chemical does not bond with these materials, meaning it can easily migrate into the air, soil, water, and dust. This increases the chances of exposure through inhalation, skin contact, and even ingestion, primarily through contaminated fish. The EPA's evaluation found that:
- Of the 21 conditions of use assessed, seven contribute to risks for workers, while three contribute to risks for consumers.
- Although TCEP can accumulate in fish, the EPA found no significant risk to land animals.
What’s Next?
As a result of the risk evaluation, the EPA plans to introduce a proposed rule aimed at reducing or eliminating the risks posed by TCEP to both people and the environment. This rule will be a crucial step in safeguarding human health and ecosystems from the harmful effects of this hazardous chemical.
Conclusion
The EPA's final risk evaluation of TCEP underscores the importance of regulating chemicals that pose a risk to public and environmental health. By addressing the hazards associated with TCEP, the EPA is taking vital steps to protect communities and ecosystems across the U.S. Stay tuned for further updates as the EPA moves forward with its regulatory action on TCEP.
