17 Φεβ 2023 · While trifluoroacetic acid has limited technical uses, the highly water-soluble trifluoroacetate (TFA) is reported to be present in water bodies at low concentrations. Most of the TFA in the environment is discussed to arise from natural processes, but also with the contribution from decomposition of environmental chemicals.
5 Μαΐ 2023 · A recently published hazard and risk assessment reviews the mammalian toxicity of trifluoroacetic acid (TFA) and human exposure to assess the margin of exposures (MoE) (see note 1). The publication is particularly timely, due to its relevance to the public consultation for the PFAS restriction proposal.
17 Φεβ 2023 · While trifluoroacetic acid has limited technical uses, the highly water-soluble trifluoroacetate (TFA) is reported to be present in water bodies at low concentrations.
HF as well as sodium and ammonium bifluorides have been shown to cause clinically significant electrolyte disturbances that can lead to dysrhythmias and fatalities. While TFAA may be structurally similar, it does not appear to have similar toxicity.
This assessment report provides background information on trifluoroacetic acid (TFA) together with its potential relevance as a risk factor to the environment and human health.
As an acid or as a salt TFA is low to moderately toxic to a range of organisms. Based on current projections of future use of HCFCs and HFCs, the amount of TFA formed in the troposphere from substances regulated under the MP is too small to be a risk to the health of humans and environment.
13 Μαρ 2024 · Trifluoroacetic acid (TFA) is a known and persistent pollutant in the environment. Although several direct anthropogenic sources exist, production from the atmospheric degradation of fluorocarbons such as some hydrofluorocarbons (HFCs) has been a known source for some time.
