Alarming Study Reveals Skiers are Leaving Harmful ‘Forever Chemicals’ on Slopes | PFAS

EnvironmentAlarming Study Reveals Skiers are Leaving Harmful 'Forever Chemicals' on Slopes | PFAS
Skiing is a beloved winter activity, but recent studies have raised concerns about the environmental impact of the sport. A study conducted by the James Hutton Institute in Aberdeen and the University of Graz in Austria has revealed that skiers are leaving behind harmful “forever chemicals” known as per- and polyfluoroalkyl substances (PFAS) on ski slopes. These PFAS chemicals, widely used in industrial processes, firefighting foams, and consumer products, have gained the nickname “forever chemicals” due to their persistence in the environment and resistance to breaking down.

Understanding the Threat of PFAS

The presence of PFAS in ski wax, commonly used by skiers to make their skis more slippery, has raised significant concerns about the potential harm these chemicals pose to both the environment and human health. The study found that 14 different types of PFAS chemicals, commonly used in ski wax, were detected in soils at family skiing spots in the Austrian Alps at levels significantly higher than in non-skiing areas. This alarming discovery has sparked worries about the accumulation and spread of PFAS into the wider environment, including groundwater systems. These concerns are not unfounded, as some PFAS have been linked to various health issues, including cancers, thyroid disease, immune system problems, fertility issues, and developmental defects in unborn children. The persistent nature of these chemicals means that they can linger in the environment for hundreds of years, posing a long-term threat to ecosystems and human health.

Skiing and the Spread of PFAS

The study’s lead researcher, Viktoria Müller, highlighted the potential risks associated with the use of PFAS in ski wax. The chemicals, once applied to skis, can be left behind on the slopes, posing a threat long after the skier has completed their run. Even areas where skiing is not prevalent showed small traces of PFAS, indicating the widespread impact of these chemicals in the environment.

The widespread use of PFAS in consumer products and industrial processes has contributed to the pervasive presence of these chemicals in the environment. It’s not just ski slopes that are affected; PFAS have been found in drinking water sources across England and even in the sea in the Netherlands. The global presence of these harmful chemicals has prompted scientists and conservationists to advocate for a blanket ban on PFAS due to their persistent nature and toxic effects.

Addressing the Issue: Bans and Sustainability

In response to the potential risks posed by PFAS, ski resorts and professional racing events have moved to ban ski wax containing these chemicals. The ban reflects the growing recognition of the need to address the environmental impact of skiing and take proactive measures to reduce the spread of harmful substances. The long-term sustainability of winter sports and outdoor recreational activities hinges on adopting practices that minimize ecological harm. Efforts to address the presence of PFAS extend beyond skiing, as communities and policymakers grapple with the challenge of mitigating the widespread impact of these chemicals. The call for a blanket ban on PFAS reflects the urgency of the situation and the need for comprehensive action to safeguard the environment and public health.


The findings of the study shine a light on the unintended environmental consequences of skiing and the widespread presence of PFAS in ski slopes. As skiers revel in the thrill of navigating slopes, the lingering impact of harmful chemicals poses a significant challenge that demands attention and action. From advocating for bans on PFAS-containing ski wax to promoting sustainable practices, addressing the issue of “forever chemicals” in skiing requires a concerted effort from all stakeholders. The future of skiing and outdoor recreation hinges on embracing eco-friendly practices and minimizing the environmental footprint of cherished winter activities.
