Scientists at Columbia University warned this through research “Water bottles contain hundreds of thousands of microparticles per liter” and warned that “they can easily pass through organs such as the intestine and lungs, directly entering the bloodstream and reaching the heart and brain.”
The study carried out by the American institute was published in the journal Proceedings of the National Academy of Sciences (PNAS) and revealed shocking results.

Authoritarians don’t like this
The practice of professional and critical journalism is a fundamental pillar of democracy. This is why it bothers those who believe they are the holders of the truth.
Some hypotheses even propose it nanoplasticsthey can cross the placenta in pregnant women, affecting developing fetuses.
Specialists of the United States Chamber of Higher Education have classified seven types of plastic: polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl, low density polyethylene, polypropylene (PP), polystyrene (PS) and other composite materials.

Microplastics: the danger of the invisible
Globally, plastic production approaches 400 million tons per year. Of these, more than 30 million are discharged into waters and onto land each year.
“When plastic decomposes, it breaks into smaller pieces instead of breaking down like organic matter would,” the experts explained. THE microplastics and nanoplastics are such that scientists still don’t know how small these particles might be.

The results showed that 10 to 100 times more plastic fragments were found per liter of bottled water than previously estimated.
