The United States Environmental Protection Agency (EPA) has banned two hazardous chemicals—trichloroethylene (TCE) and perchloroethylene (PCE or perc)—commonly used in cleaning products and other household items. The announcement, made on December 9, marks a significant step toward reducing the risks associated with these substances, which have been linked to various cancers and other health conditions.
The Dangers of TCE and Perc
TCE, a solvent found in degreasers, paint strippers, carpet cleaners, and adhesives, is notorious for its harmful effects on human health and the environment. It can seep into soil and groundwater, creating toxic plumes that release harmful gases into homes and businesses. Studies estimate that TCE contaminates 9% to 34% of U.S. water supplies and has been linked to Parkinson’s disease.
High-level exposure to TCE can result in kidney cancer, liver cancer, nerve damage, and autoimmune diseases, while lower levels can cause headaches, dizziness, and skin rashes, according to the Centers for Disease Control and Prevention (CDC).
Perc, predominantly used in dry-cleaning processes, poses similar risks. It can contaminate air, soil, and water, affecting people living near dry-cleaning facilities. The chemical has been associated with headaches, mood changes, liver and kidney damage, and even certain cancers like bladder cancer after prolonged exposure.
What the Ban Means
“This ban is a victory for public health,” said Dr. Samuel Goldman, a University of California, San Francisco professor specializing in environmental risk factors for diseases. However, Goldman emphasized that the bans are a preliminary step, noting that these chemicals persist in the environment for decades after being released.
The EPA’s bans will not take effect immediately. Industries using TCE and perc in consumer and industrial products have been given varying deadlines for compliance.
TCE: Must be removed from all products within a year, with exceptions for certain industries like aerospace and medical device manufacturing, which have extended timelines.
Perc: Consumer products must eliminate the chemical within three years, while dry-cleaning facilities have 10 years to phase it out entirely. Starting in six months, dry cleaners will no longer be able to purchase new equipment that uses perc.
Steps to Protect Yourself
Until the bans are fully implemented, consumers can take steps to minimize exposure:
Check Labels: Look for “trichloroethylene” or “perchloroethylene” on product ingredient lists.
Choose Green Options: Patronize “green” dry cleaners that avoid using harmful chemicals.
Filter Your Water: Use activated carbon filters on your refrigerator or sink or install whole-house systems to remove contaminants.
The Environmental Working Group (EWG) offers a map showing TCE contamination levels by area, allowing individuals to assess local risks.
While the bans signify progress, much work remains to address the lingering environmental impact of these chemicals. As Dr. Goldman noted, stopping the use of TCE and perc is just the beginning of mitigating their long-term effects.
