A recent study involving 110 volunteers from nine European countries found that every participant tested positive for trifluoroacetic acid (TFA), a type of per- and polyfluoroalkyl substances (PFAS), often referred to as "forever pollutants" due to their persistence in the environment. The results, published by European green lawmakers, were highlighted by the French news outlet Franceinfo. TFA, which is present in water and agricultural crops, was detected in all the blood samples analyzed, with a median concentration of 21.2 ng/mL. According to the Greens/ALE group in the European Parliament, these levels are the highest reported in human studies to date. TFA is known for its extreme stability, making it particularly persistent in the environment. It is highly mobile and very water soluble, found in all environments, and cannot be removed by standard water treatment processes. Marie Toussaint, a European green lawmaker, described the 100% contamination rate as "extremely serious," noting that it was unexpected because "we expected slightly less." She hopes the study, which was commissioned by her political group, will raise awareness across Europe about the widespread presence of TFA. The study, however, does not provide enough data to determine how much of the contamination is due to the participants' professional activities. Nevertheless, it contributes to a larger discussion on monitoring exposure and protecting workers. As a result, the lawmakers are urging the European Union to implement broad restrictions on the use of PFAS, including TFA. Among their seven proposals at the European level, they suggest setting "occupational exposure limits for PFAS to strengthen the protection of workers," recognizing health issues linked to PFAS as occupational diseases, and developing "a reference health value based on TFA blood concentrations to better assess the risks of human exposure."
