Federal regulators are considering a partial ban or other restrictions on tris(2-chloroethyl) phosphate (TCEP), a chemical commonly used as a flame retardant in paints, textiles, foams and building materials. and that it poses an unreasonable risk. humans and the environment.

The U.S. Environmental Protection Agency (EPA) released a draft risk assessment on December 14 that identifies serious health and environmental risks associated with TCEP exposure and will solicit public comment over the next 60 days before finalizing regulatory action. We have indicated that we will consider peer review feedback. .

TCEP is a colorless liquid chemical used primarily as a flame retardant or plasticizer in aircraft products, laboratory chemicals, textiles, paints, and coatings. However, EPA officials have indicated that they have determined that exposure to TCEP is associated with kidney, neurological, reproductive, and developmental problems, as well as cancer. It has also been assessed that the chemical poses an unreasonable risk to aquatic animals, including fish.

TCEP risk assessment

The EPA report is part of the chemical risk assessment process under the Toxic Substances Control Act (TSCA), which requires EPA to identify and regulate chemical exposure risks. This process has recently been strengthened to allow final decisions on whether a chemical poses an unreasonable risk to the public.

The previous EPA administration conducted its first chemical risk assessment, including TCEP, in August 2020. However, tribes, community advocates, legislators, and even the EPA’s scientific advisors have not investigated TCEP exposures to fish species that are part of tribal nations’ traditional diets and have not used the chemical. The study was criticized because it did not include airborne exposures near factories that were infected. There are several factors such as.

The new TCEP risk assessment submitted by the current EPA administration includes additional exposure factors not previously considered. This is the first of 20 draft chemical risk analyzes that EPA plans to release over the next year.
