Tóxicos: Cómo las "sustancias químicas permanentes” están dañando nuestra salud | DW Documental
DW Documental・2 minutes read
PFAS are harmful synthetic chemicals used in various industries but linked to serious health issues and environmental contamination, prompting the EU to consider strict regulations despite industry opposition. As efforts to transition away from PFAS develop, including alternative firefighting foams and textiles, the complexities of managing existing contamination and the high costs associated with cleanup challenge progress.
Insights
- PFAS, or perand polyfluoroalkyl substances, are synthetic chemicals with widespread applications due to their water- and fat-repelling properties, but they pose significant health risks such as fertility issues and certain cancers, leading to increased regulatory scrutiny from the EU despite industry pushback on their essential role in technology and manufacturing.
- The ongoing challenges of PFAS contamination highlight the complexity of remediation efforts, as seen in the destruction of contaminated crops like strawberries resulting in severe financial losses for farmers, and the need for costly purification systems, indicating that addressing this pervasive environmental issue will require substantial investment and a coordinated regulatory approach.

Recent questions
What are PFAS chemicals?
PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals that have been in use for around 80 years. They are known for their unique properties, such as being non-flammable and repelling water and fat, which makes them valuable in various industries. PFAS are commonly found in products like fast food packaging, firefighting foams, and even medical devices like artificial heart valves. However, their stability and resistance to breakdown in the environment raise significant concerns about their long-term impact on health and ecosystems.
How do PFAS affect human health?
PFAS have been linked to a range of serious health issues, including fertility problems, reduced effectiveness of vaccines, and certain types of cancer. The presence of these chemicals in the environment poses a risk to human health, as they can accumulate in the body over time. Studies have shown that exposure to PFAS can lead to adverse health outcomes, prompting regulatory bodies, particularly in the EU, to consider stricter regulations to limit their use and mitigate their harmful effects on public health.
Why are PFAS difficult to remove from the environment?
PFAS are notoriously difficult to break down due to their strong chemical bonds, which makes them persistent in the environment. They can accumulate in soil and groundwater, particularly near industrial sites and airports where they are commonly used. Traditional methods of environmental cleanup often fall short when it comes to PFAS, as they resist degradation and can leach into water sources. This persistence leads to widespread contamination, complicating efforts to manage and remediate affected areas effectively.
What regulations exist for PFAS in Europe?
In Europe, there have been various regulations aimed at controlling the use of PFAS due to their environmental and health risks. The EU has implemented bans on certain PFAS and established limits on their presence in drinking water. However, there is currently no comprehensive global agreement addressing PFAS contamination, leading to ongoing discussions about the need for a unified approach to manage these chemicals. The regulatory landscape is evolving, with calls for stricter measures to phase out PFAS and protect public health and the environment.
How are farmers affected by PFAS contamination?
Farmers are significantly impacted by PFAS contamination, particularly when it comes to crop production. Testing for PFAS in agricultural products, such as oats and strawberries, is crucial, as contaminated crops cannot be sold, leading to substantial financial losses. For instance, a case involving the destruction of strawberries due to PFAS contamination resulted in losses of up to €80,000. Farmers must also invest in water purification systems to ensure their irrigation sources are safe, adding to their operational costs and complicating their agricultural practices.
