Debunking the Myths: Are there really 84,000 chemicals?
If you’ve ever read a news article or blog post about chemicals, you may have heard the oft-cited claim that there are 84,000 chemicals in commerce but only 200 of these have been tested for safety. What you may not know is that this “statistic” is entirely false. Unfortunately, it has taken on a life of its own thanks to the effective way it can be used to provoke fear and distrust in an unsuspecting audience.
So let’s take a look at the facts:
· The federal chemical regulation law known as the Toxic Substances Control Act (TSCA) required the U.S. Environmental Protection Agency (EPA) to keep a list of all chemicals manufactured or processed in the United States. This TSCA Chemical Substance Inventory included roughly 84,000 chemicals – but this number also included numerous duplications, as well as chemicals that were no longer being produced and used.
· TSCA was updated, with the passage of the Lautenberg Chemical Safety for the 21st Century Act (LCSA) in June 2016. The new law amended TSCA and required EPA to “reset” the inventory and designate chemicals currently in use.
· Under the amended TSCA, manufacturers were required to report to EPA chemical used in commerce from June 2006 through June 2016. The latest draft of the inventory listed 38,304 chemicals, representing many chemicals that are not used in commerce today or are only being produced in very small amounts.
· The CDR requires manufacturers to provide EPA with information every four years on the chemicals they produce domestically or import into the United States. The 2016 CRD showed 8,707 chemicals used in commerce.
· EPA is using the TSCA Chemical Substances Inventory to screen chemicals based on hazards, uses and typical human exposures. This includes consideration of impacts on vulnerable groups and the environment, proximity to drinking water sources and other relevant information. The screen will be used to prioritize the chemicals EPA should focus on first in its risk evaluation.
· EPA has required significantly more testing than the “200 chemicals” figure cited. This figure only reflects testing done under one part of TSCA (Section 4) and overlooks testing EPA had required under TSCA’s “significant new use rule provisions” (Section 5).
· The LCSA gives EPA authority to immediately begin a risk evaluation for any chemical it designates as a “high priority.”
· IF EPA’s risk evaluation determines that a chemical or a specific use of a chemical presents an unreasonable risk, EPA can apply risk management measures including labeling requirements, use restrictions, phase-outs and bans.
The LCSA requires that EPA screen all chemicals in active use, with a focus on “high priority” chemicals.
Besides LCSA, new chemicals also must comply with myriad federal regulations, including the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, Federal Food, Drug and Cosmetics Act, Emergency Planning and Community Right-to-Know Act, Consumer Product Safety Act, Federal Hazardous Substances Act and more.
The following illustrates the rigorous review process that new chemicals undergo before they are used in products.
Consumers also should have access to safety information about chemicals. The Responsible Care Product Safety Code requires chemical manufacturers to evaluate and continuously improve product safety, while also making information about chemical products available to the public.
Chemical safety and providing transparent information about chemicals is a top priority for the chemical industry. Working with all stakeholders along the supply chain, the chemical industry is working to maximize the safety, efficacy and sustainability of all of the products it manufactures.
