On October 25, 2021, the U.S. Environmental Protection Agency released its final human health toxicity assessment for hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt (referred to as “GenX chemicals”). HFPO dimer acid and its ammonium salt are the major chemicals associated with the processing aid technology developed by DuPont with the trade name GenX. GenX chemicals are part of the PFAS class, which replaced perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) that are no longer used in the United States. However, the …

Coming shortly after the September 23, 2021, enactment of the U.S. Environmental Protection Agency’s rule calling for an 85% reduction in hydrofluorocarbons (HFCs) over the next 15 years, the agency maintained its momentum on October 8, 2021, granting 10 petitions submitted under the American Innovation and Manufacturing (AIM) Act to further reduce HFCs.

The AIM Act, enacted in December 2020, specifically directs the EPA to address HFCs in three areas; phase down their production and consumption, manage the use of existing HFCs and alternative chemicals, …

On August 18, 2021, the U.S. Environmental Protection Agency issued a pre-publication notice of a final rule banning the use of the pesticide chlorpyrifos on food in order to better protect human health. Chlorpyrifos is an insecticide used for a number of agricultural and non-food applications. It has been linked to numerous health risks including neurodevelopmental risks to infants and children, and harm to agricultural workers who work with the pesticide.

Per the final rule, the EPA announced the revocation of chlorpyrifos “tolerances”—which establish the …

Methylene chloride (MC) is used as a paint-stripping solvent, an aerosol propellant, in the manufacture of film, and as a solvent in drug manufacturing. In the research laboratory and in food production, it is commonly used for extractions. It has also been clinically demonstrated to cause liver and lung cancer in animals and may be a carcinogen to humans, causing severe irritation and burning to the skin and eyes with exposure above recommended levels.

Because of these risks and in response largely to public pressure, …

In response to recent Executive Orders issued by President Biden, the U.S. Environmental Protection agency recently announced that it will be changing how it evaluates chemical risk under the Toxic Substances Control Act (TSCA). These changes will affect risk evaluations going forward, as well as 10 chemicals already evaluated by the EPA under the last administration. The EPA stated that the policy change is meant to ensure the public is protected from unreasonable risks from chemicals in the marketplace while relying on support that is …
