Nowhere on our planet is it safe to drink rainwater, according to a new study by scientists at Stockholm University.
The toxic chemicals known as PFAS (per- and polyfluoroalkyls), also known as “forever chemicals,” were previously found in packaging, shampoo or makeup, but have spread to our entire environment, including water and air. So it is also in the rainwater.
According to the measurements taken by the researchers, there is nowhere else on Earth where rainwater would be safe to drink. Even in Antarctica or the Tibetan Plateau, stormwater levels are above drinking water guidelines. The two regions are normally considered pristine and still have PFAS levels “14 times higher” than the drinking water guidelines.
Fertility problems and developmental delays in children
Once ingested, PFAS accumulate in the body. According to some studies, exposure can also lead to fertility problems, developmental delays in children, increased risk of obesity or certain cancers (prostate, kidney and testicle), and an increase in cholesterol levels.
PFAS is the collective name for more than 6,000 chemical substances that include a combination of fluorine compounds and alkyl groups. They do not occur naturally in the environment.
PFAS are resistant to high temperatures and are water, dirt and grease repellent. Therefore, they are widely used in industrial applications and consumer products. Think of the non-stick coating in pans, cosmetics, textiles, fire extinguishing foam, cleaning agents or lubricants.
