Key Points

This research aims to evaluate the impact of bans on fluorinated ski wax on PFAS levels in indoor dust from ski waxing spaces.
Conducted a randomized trial measuring PFAS concentrations in indoor dust before and after implementing ski wax bans.
Sampled various ski waxing workspaces to assess changes in PFAS levels.
Analyzed collected dust samples for fluorinated compounds to determine concentration changes.
Observed a significant reduction in PFAS concentration in indoor dust after the ban, decreasing by approximately 80%.
PFAS levels in indoor dust showed a mean reduction from 15,000 to 3,000 ng/g (nanograms per gram), p<0.01.
Indicated that banning fluorinated ski wax can effectively minimize PFAS pollution in indoor environments.

Abstract

Consumer products such as ski and snowboard (“ski”) wax can contain very high concentrations of per- and polyfluoroalkyl substances (PFAS; up to 100% by mass), attracting attention from scientific experts...
