Ski wax can expose users to perfluorochemicals that build up in their bodies and carry potentially serious health risks. Racers, in particular, covet waxes with high amounts of fluorinated compounds because they make skis and snowboards go faster. But that extra speed could come at a cost. Wax technicians working for World Cup ski race teams had median levels of one compound that were up to 45 times higher than the general population’s. Exposure could be risky, especially to thousands of junior ski racers and parents who may layer on highly fluorinated race wax week after week without knowing how to handle it safely.
