Fluorella has been a big issue in the ski world in recent weeks. According to NRK, it has been possible to find harmful traces of fluoride in the soil around the tracks in Lillehammer and Holmenkollen. According to Anna Kärrman, associate professor of environmental chemistry at Örebro University, it is also most likely that there are traces of fluoride in Lugnet in Falun.

FIS announced earlier this fall that it would ban the fluorine field from May 2020. Among the biathlon association, the case is being investigated but has not yet reached a decision. Sweden's best biathlete on the men's side, Sebastian Samuelsson, believes that the fluoride ramp should be banned as soon as possible.

- We have to get rid of the fluoride wall as soon as possible and I think that everyone is aware of this, says Samuelsson.

"Getting too much competitive advantage"

But despite the fact that Samuelsson is well aware of the risks associated with the health hazard, the biathlon says he will not stop using it until there is a concrete decision.

- It's a huge problem, of course. But if we do not use the fluorine wall then it will be a too big advantage for the competitors that there is no sense to compete at all, says Samuelsson to SVT Sport.

For Samuelsson, it is important that the fluorine embryo is banned, but also that the controls work after a possible ban.

- I don't think the problem will be to find any alternatives to whaling, but the alternatives will make it slower. Then it is important that there is a good test method for detecting it so that people do not use the fluoride wall, says Samuelsson to SVT Sport.
