Trifluoroacetic Acid (TFA): An Emerging Threat to Water Resources and Drinking Water Safety
Trifluoroacetic acid (TFA) has emerged as one of the most widespread and persistent fluorinated contaminants detected in the environment. As an ultra-short-chain member of the per- and polyfluoroalkyl substances (PFAS) family, TFA exhibits exceptional water solubility, high mobility, and extreme environmental persistence. Unlike legacy PFAS such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), TFA is primarily generated through the degradation of fluorinated refrigerants, pesticides, pharmaceuticals, and industrial chemicals. Recent monitoring studies have revealed its increasing occurrence in rainwater, groundwater, surface waters, drinking water, food products, and even human serum. This review aims to summarize current knowledge regarding TFA sources, … Continue reading
