The German Federal Office for Chemicals (BfC) has recently submitted a significant proposal to the European Chemical Agency (ECHA), aiming to classify trifluoroacetic acid (TFA) and its inorganic salts as reproductive toxicants. This proposal is rooted in new scientific evidence that links exposure to TFA, an atmospheric by-product of certain refrigerants and pesticides, to reproductive toxicity.
TFA is a persistent chemical that falls under the PFAS (per- and polyfluoroalkyl substances) category, known for their long-lasting presence in the environment. These chemicals, often referred to as “forever chemicals,” have been found in various environmental mediums, such as water bodies and soil, primarily through atmospheric deposition and runoff from agricultural activities.
BfC’s proposal outlines the potential hazards of TFA, emphasizing its capability to cause reproductive harm, with a proposed classification of Repr. 1B (suspected human reproductive toxicant). This classification is based on animal studies indicating adverse effects on fertility and development. Additionally, TFA’s current classification as an acute toxicant when inhaled would be elevated from Acute Toxicity 4 H332 to Acute Toxicity 3 H331, reflecting its higher toxicity levels.
The German agency also suggests that TFA and its salts be categorized under hazard classes PMT (persistent, mobile, and toxic) and vPvM (very persistent, very mobile). These classifications underline TFA’s potential to cause widespread and long-lasting contamination of water resources, which poses significant environmental and health risks.
This proposal initiates an 18-month review process by ECHA’s Committee for Risk Assessment (RAC), inviting stakeholders to contribute their data and arguments. If approved, the new classification will become effective following an EU Commission decision and a transitional period.
Dr. Jan Averbeck of BfC emphasizes the necessity of this classification, based on the latest study results, to communicate TFA’s hazardous properties effectively and ensure protective measures are in place. This move highlights the ongoing efforts to address the environmental and health impacts of PFAS and other persistent chemicals.
