‘Everyone is drinking it’: Why this type of ‘forever chemical’ seems to be everywhere

Forever chemicals, known as PFAS, have been linked to health issues, prompting companies and regulators to address them. However, a new type of PFAS called TFA, found in rainwater, groundwater, and drinking water, raises concerns due to its widespread presence. TFA is difficult to filter and may accumulate in the body, posing potential health risks. Its increasing levels are attributed to the use of refrigerants and heating/cooling systems. While research on TFA's health effects is ongoing, scientists are concerned about its persistence and potential long-term impacts. Studies have shown high levels of TFA in indoor and outdoor environments, as well as in drinking water. The Environmental Protection Agency is monitoring TFA but has not yet implemented regulations. Some efforts to address TFA include the potential classification as a reproductive toxicant in Germany and the identification of its harmful effects in the European Union. Chronic exposure to TFA through daily sources like drinking water and products remains a potential concern for health risks.
