Plastics are omnipresent - in our clothes, packaging and even in our food. However, many studies show that certain chemicals contained in plastics could pose serious health risks. Particularly problematic are so-called "perpetuating chemicals" (also known as PFAS), which affect our hormone balance and have been linked to diseases such as cancer, diabetes and fertility problems.
Scientists at MIT have made a promising discovery: a newly developed filter made from natural materials such as silk and cellulose could help to remove these pollutants from water. In the long term, this innovation could revolutionize the way we deal with contaminated drinking water.
Studies by the US Centers for Disease Control and Prevention (CDC) show that around 98% of people have traces of PFAS in their bodies. This sounds alarming, but there is also good news: Despite their name, these chemicals don't stay in the body forever. Those who reduce their exposure can minimize the risk and even eliminate it completely in the long term.
The U.S. Environmental Protection Agency (EPA) estimates that the cleanup of PFAS-contaminated water will cost around 1.5 billion US dollars annually. The new filter technology could offer a more cost-effective and sustainable alternative. However, further research is needed to confirm the scalability and effectiveness of this method.
Until this new technology is widely available, there are some simple steps you can take to reduce your exposure to eternal chemicals:
Store food smartly: use glass, stainless steel or ceramic instead of plastic containers.
Avoid plastic where possible: Don't heat food in plastic containers as this can release harmful substances.
Pay attention to recycling codes: Avoid containers with the numbers #3 (phthalates), #6 (styrene) and #7 (bisphenols) as they may contain problematic substances.
Check cosmetics and household products: Choose products labeled "phthalate-free," "paraben-free" or "BPA-free."
Reduce ultra-processed foods: The less packaging involved, the less likely it is that contaminants will transfer into your food.
Eternal chemicals are a serious problem, but with new innovations and more conscious behavior, you can significantly reduce your risk. While scientists continue to research sustainable solutions, you can already implement simple changes in your everyday life to protect yourself and your health.
