Einige Flaschenwassermarken enthalten deutlich mehr Mikroplastik als Leitungswasser. Die Ergebnisse zeigten, dass in Flaschen abgefülltes Wasser dreimal so viele Nanoplastikpartikel enthielt wie das aufbereitete Trinkwasser.

Some bottled water worse than tap for microplastics, study shows

**Some brands of bottled water contain significantly higher levels of microplastics than tap water**, according to new research by scientists who have developed a novel method for detecting these tiny particles.

The result of a global buildup in plastic pollution, microplastics and nanoplastics are small synthetic particles produced when plastic products are used or degrade. These plastic fragments are found nearly everywhere in the environment, including the nation’s waterways.

To better understand the concentration levels in a segment of the U.S. water supply, scientists analyzed water samples from four treatment plants near Lake Erie and six different brands of bottled water. Their **results showed that bottled water contained three times as many nanoplastic particles as the treated drinking water**, said Megan Jamison Hart, lead author of the study and a PhD candidate in environmental sciences at The Ohio State University.

“We can make educated choices to try and reduce our daily exposure to these harmful chemicals,” said Hart. “For the average person who is thirsty and wants a drink, the best way to do that would be drinking it straight out of the tap rather than grabbing pre-bottled water.”

While previous research evaluated the presence of microplastics in different drinking water sources few have centered on nanoplastics, likely because their extremely small size makes them a challenge to study, said Hart. Using a combination of imaging (scanning electron microscopy) and chemical identification (optical photothermal infrared spectroscopy) techniques allowed the team to detect and identify particles down to their smallest parts.

The study was recently published in the journal Science of The Total Environment.

I hate everything about this. We’ve been getting quarterly letters about the PFAS levels in our tap water. There were other studies on how [filtration systems will leak nanoplastics](https://apnews.com/article/plastic-nano-bottled-drinking-water-contaminate-b77dce04539828207fe55ebac9b27283#:~:text=Much%20of%20the%20plastic%20seems,author%20Naixin%20Qian%2C%20a%20Columbia%20physical%20chemist.) itself and bottled water is just filtered water contained in more plastics. Please, make it make sense. I’ll take plastic over PFAS for now but it’s only due to the huge gap in our understanding of how plastics affects our bodies.

What brands are best and how can i minimise my intake?

Aren’t we all just fucked already? It’s literally everywhere they look so might as well drink up, no?
