13 Μαρ 2024 · Many long-chain PFASs have been found to potentially cause adverse effects on human and animal health in several in vitro and in vivo studies [2,3,4,5,6,7,8,9], to be ubiquitous and persistent in the environment, and to bio-magnify along food chains [2,10,11,12,13,14,15].
Long-chain PFCs are found world-wide in the environment, wildlife, and in humans (Giesy and Kurunthachalam 2001). They are bioaccumulative in the food chains of air-breathing vertebrates (Houde et al. 2006) and are toxic to. Figure 1. Structure of TFA. Green = fluorine, grey = car-bon, red = oxygen, white = hydrogen.
1 Νοε 2024 · Through the application of C-CF 3 -containing plant protection products (PPP) in agriculture, a substantial quantity of trifluoroacetate (TFA) can be formed and emitted. We here present estimations of TFA formation potentials from PPP across three important economical regions, namely Europe, the United States of America and China.
2 Οκτ 2024 · TFA is rapidly absorbed with food, partly fed into the enterohepatic circulation (the circulation of certain substances in the body of mammals between the intestine, liver and gall bladder), distributed in the body (including the placenta) and excreted via urine and faeces. The acute toxicity of TFA is very low.
9 Σεπ 2022 · Because of their high solubility in water and their very small octanol-water partition coefficient, TFA salts do not bioconcentrate in aquatic organisms, and do not biomagnify in the food chain. Thus, they present negligible risk to organisms higher on the food chain, including humans under conditions relevant to environmental exposure.
11 Απρ 2024 · Current research suggests that most short-chain PFASs, including TFA, do not bioaccumulate in food chains and are rapidly excreted from humans, although some reports state that Trifluoroacetic acid has the potential to bioaccumulate in plant material.
1 Ιουν 2023 · Trifluoroacetic acid (TFA) is a very persistent contaminant that has gained attention due to its multitude of anthropogenic sources, widespread occurrence in the environment, and expected accumulation in (semi-)closed drinking water cycles.
