Overview
- FIS testers detected fluorinated wax on the skis of Han Dasom and Lee Eui-jin during post-race checks after the women’s classic sprint qualification on Feb. 10 in Val di Fiemme, triggering immediate disqualifications.
- The athletes’ results were expunged from official Olympic records in line with equipment rules that ban fluor-containing products.
- A KSOC field inquiry found fluor in products the team believed were compliant, while the Korea Ski Association defended the athletes, warned the supplier, and replaced affected skis.
- Fluorinated wax, banned since the 2023/24 season due to PFAS-linked health and environmental risks, is checked using FTIR spectroscopy as part of routine enforcement at finish-area test zones.
- Both skiers, ranked 157th and 158th in the World Cup, later raced in the 10km freestyle on Thursday with their results standing as further investigations continue.
