Forever Chemicals: Damaging the Environment and Your Body

PFAS (per- and polyfluoroalkyl substances) are a large and diverse group of synthetic chemicals that have been widely used for decades. They are found in many everyday products, including water-repellent clothing, food packaging, furniture, and nonstick cookware.

These chemicals do not break down in the environment, and once released, they can bioaccumulate for years or even decades, contaminating soil, water, and wildlife for generations unless active measures are taken to remove or contain them. One recent study found evidence of forever chemical pollution at 17,000 sites in Europe alone. 

How can PFAS harm the environment and health?

PFAS contamination poses serious threats to ecosystems, with animals contaminated by hazardous forever chemicals on every continent except Antarctica. These chemicals harm wildlife health and development, disrupt soil structure and microbial communities, and contaminate rivers, lakes, and drinking water supplies. In England alone, over one-third of watercourses contain medium to high risk PFAS levels. Recently, research has revealed that levels of two potentially cancer-causing PFAS chemicals washing into the Mersey from land runoff were among the highest recorded globally. The UK is just one example- throughout Europe, PFAS contamination follows a similar pattern, with numerous sources scattered across the landscape. 

Furthermore, well-studied PFAS have been linked to a wide range of adverse health outcomes in humans, including cancer, liver toxicity, obesity, reproductive and developmental effects, and reduced fertility. In addition, PFAS exposure has been associated with immune system dysfunction, particularly immunosuppression, leading to reduced vaccine responses and increased susceptibility to infections.

What can I do about PFAS?

Firstly, you can reduce your exposure by avoiding products that contain PFAS where possible. Choose alternatives to non-stick cookware, opt for natural fabrics instead of waterproof clothing, and use glass or stainless steel containers rather than plastics. When using plastic, ensure it is PFAS-free. However, for most people, the main source of PFAS exposure is through food and water.

You can also boycott products and companies that use PFAS, many of whom are blocking regulation of toxic chemicals. Check here for a list of retailers committed to phasing out PFAS. 

Finally, take action by contacting your local representative, signing petitions for stronger regulation, or getting involved with an environmental organisation. Protecting your health and the environment starts with making your voice heard.
