A recent study reveals bottled water brands contain more nanoplastics than previously believed, with an average of 240,000 plastic fragments per liter.

The most common plastic found was polyethylene terephthalate (PET), likely from plastic filters and bottles.

These tiny particles can enter the bloodstream and organs, raising health concerns.

While the health effects of nanoplastics are still unknown, research indicates potential negative impacts on the reproductive system.

Individuals can reduce exposure to nanoplastics by consuming tap water from glass or stainless steel containers, and avoiding plastic containers for food and beverages.

Despite the study's findings, the Portuguese association for natural mineral and spring water producers claims it cannot be applied to Portugal or the EU due to their closely monitored bottled water sector.

The presence of nanoplastics is a global concern requiring further research to understand their impact on human health and ecosystems.
