In October and November, the Danish Environmental Protection Agency catches fish from 50 streams across the country.
This is done to investigate whether PFAS has polluted nearby watercourses.
This is stated by the agency in a press release.
PFAS is a group of toxic substances. The harmful fluorine PFOS belongs to this group. It was previously found in, among other things, foam for firefighting.
The streams are all in the vicinity of past and present fire drill sites.
Following major discoveries by PFOS in Korsør, the Danish Regions have designated 145 localities throughout the country, which are to be investigated further.
If municipalities or regions have needs, they can already decide to discourage fishing in watercourses near the places.
This is stated by the Danish Environmental Protection Agency. They expect answers to the tests in early 2022.
The board examines tissue samples from the fish. The PFAS substances are easily absorbed by animals and plants, the agency writes. They also degrade slowly.
If watercourses have been affected by PFAS, there is a risk that they will be found in the fish’s tissues.
