Opis:
Perfluorinated Alkyl Compounds (PFAs) are highly produced and used materials in various fields. Due to their unique properties like water repellence and grease repellence, they are very useful as surfactants and surface protectors. However, since having a strong structure these materials are highly resistant and accumulative in the environment. Because of their persistent nature and harmful potential, they are listed within materials in Stockholm Convention as persistent organic pollutants (POPs) and all uses of PFAs and derivatives are restricted. Since PFAs cannot be treated biologically, advanced treatment processes like advanced oxidation, adsorption, and membrane filtration are utilized for their removal. Within this work, their occurrence and treatment situations will be evaluated according to the literature data.

Opis:
The purpose of the work was to review the literature and characterize organic micropollutants from the group of perfluorinated surfactants - PFAS. It is a result of the proposal to include these compounds in the new Water Directive on the list of compounds which control in drinking water will be required and subject to inspection. The group of these organic bonds includes several thousand compounds in which fluorine is linked to the (straight or branched) chain of aliphatic hydrocarbons instead of hydrogen. The article describes the permissible concentrations of PFAS in waters, the properties of these compounds, their potential impact on organisms, concentrations identified in waters, and indicates the need to limit the emissions of these compounds to surface waters. This is an important problem from the point of view of these compounds’ impact on organisms and the fact that such waters are often a source of water supply for the national economy, including consumption by the population.
