Lovande metod för att stoppa PFAS-läckage vid brandövningsplatser

Quick Look

  • Forskare vid Statens geotekniska institutet har testat en metod med aktivt kol i marken för att stoppa PFAS-läckage från förorenade brandövningsplatser vid Sundsvalls och Örnsköldsviks flygplatser.
  • Metoden beskrivs som lovande och enkel, och tusentals platser i Sverige kan vara förorenade av PFAS från brandskum.

AI-generated summary

Why It Matters

PFAS-ämnen finns i brandskum och har förorenat många brandövningsplatser. Kemikalieinspektionen klassar ämnena som hälsofarliga och de sprider sig snabbt i grundvatten.

Font size

PFAS finns bland annat i brandskum och många brandövningsplatser har blivit kraftigt förorenade. Kemikalieinspektionen betraktar PFAS-ämnena som hälsofarliga och ämnena sprider sig snabbt om de kommer i kontakt med grundvattnet.

– Det finns tusentals platser där man använt brandskum som kan innehålla PFAS, säger hydrogeologen Robert Earon på Statens geotekniska institut, SGI, som ligger bakom den nya forskningen.

Lovande metod

SGI:s forskning har gjorts på uppdrag av regeringen och utförts vid brandövningsplatser vid Sundsvalls och Örnsköldsviks flygplatser. Där har aktivt kol använts i marken och metoden beskrivs som både lovande och förhållandevis enkel.

I videon ser du hur Robert Earon och hans forskarlag har gått till väga för att stoppa PFAS-läckaget.

Open Questions

  • ?Hur kostnadseffektiv är metoden med aktivt kol i större skala?
  • ?Finns det risk för att kolet självt blir en föroreningskälla över tid?
  • ?Hur många av de tusentals misstänkta platserna kommer att saneras med denna metod?
