Bottled water is not that pure, it actually contains tens of thousands of plastic particles that can pose a health risk! Tristan Bergen 01/13/2024 10:00 5 min
According to a recent American study published in early 2024, plastic bottled water contains many more microparticles made of plastic than we had previously imagined.
Thousands of particles in every bottle!
Thanks to a revolutionary technology that uses lasers in particular, researchers from Columbia University in the US state of New York recently highlighted the presence of many microscopic particles in plastic bottles.

These tested Three popular brands that are regularly consumed by many locals and came to the conclusion that plastic bottles generally contain much more microplastics than previously assumed. Actually there are quite a few 240,000 plastic fragments per liter of water discovered in this study!
For reasons of fairness, the scientists responsible for the study did not want to reveal which brands were tested. However, they are convinced that all plastic water bottles sold commercially contain nanoplastics. This is what the results showed Each liter of water contained between 110,000 and 370,000 particles per liter, including 90% nanoplastics and 10% microplastics.

The most common type of plastic was nylon, which worked particularly well come from plastic filters used to purify waterfollowed by polyethylene terephthalate, Element used to make water bottles. These results therefore raise an important question about the potential health risks for regular bottled water consumers.
A health risk?
Plastic particles are present everywhere on earth, with plastic being one of the most commonly used materials by humans. Microplastics measure with a diameter of less than 5,000 micrometers and are the least abundant elements in bottled water, according to this study.

However, nanoplastics are much smaller, with a size of less than one micrometer, or half the size of a bacterium. These nanoplastics are therefore so small that they can be used e.genter the blood system and spread to our organs, including the brain and heart. Some studies have also succeeded in detecting the presence of nanoplastics even in our cells.
Research into its consequences is still limited because scientists have only recently become aware of this problem. However, some studies have already highlighted harmful effects, particularly on the reproductive system. For example, a study published in 2020 showed that the most toxic nanoplastics could Reduce the amount of motile sperm in Pacific oysters by 79% !

However, scientists advise against stopping drinking bottled waterOnly the risk of dehydration is greater than the possible consequences of exposure to nanoplastics Limit it to what is necessary. A reasonable alternative would be rather switch to tap water, which also contains microplastics, but in significantly smaller quantities. However, further larger-scale tests are planned in the coming months, which will also be carried out with tap water.
