Abstract

Per- i polifluoroalkilne tvari stabilni su kemijski spojevi koje je sintetizirao čovjek, sa širokom primjenom u industriji i u potrošačkim proizvodima. Izuzetno su otporni na razgradnju i imaju veliki potencijal bioakumulacije, zbog čega su se proširili u cijeloj bioti. PFAS pokazuju toksični učinak na organizme. Za uklanjenje PFAS iz onečišćenog okoliša i otpadnih tokova mogu se koristiti metode poput reverzne osmoze, adsorpcije na aktivni ugljen, sonoliza, fotorazgradnja, međutim, takvi postupci primjenjuju visoki tlak i temperaturu, nepraktični su za in situ uklanjanje, skupi su, i rezultiraju s toksičnim otpadom. Biorazgradnja PFAS je ekološki i ekonomski povoljna alternativa, pogotovo za in situ remedijaciju. Lignolitičke funge pokazuju potencijal za biorazgradnju PFAS. Također, enzimski katalizirane oksidativne humifikacijske reakcije bi se potencijalno mogle koristi za remedijaciju nekih PFAS.

Abstract (english)

Per- and polyfluoroalkyl substances are stable man-made chemical compounds with wide application in industry and in consumer products. They are extremely resistant to degradation and have a high bioaccumulation potential, which is why they have spread throughout the biota. PFAS show a toxic effect on organisms. Methods such as reverse osmosis, adsorption on activated carbon, sonolysis, photodegradation can be used to remove PFAS from polluted environments and waste streams, however, such procedures apply high pressure and temperature, they are impractical for in situ removal, expensive, and result in toxic waste. Biodegradation of PFAS is an environmentally and economically favourable alternative, especially for in situ remediation. Lignolitic fungi show potential for PFAS biodegradation. Also, enzyme-catalysed oxidative humification reactions could potentially be used for remediation of some PFASs.
