Weather of Arabia - American scientists have confirmed that water bottled in plastic contains ultra-fine plastic particles that pose a major threat to human health, and a recent study conducted by Columbia University in New York revealed that a medium-sized water bottle may contain about 240,000 particles of plastic that are harmful to health, according to For a report from Bloomberg.
This new study shows that the average water bottle contains a large amount of nanoplastic particles, which can stick to the machinery of human cells. The results are published in the journal Proceedings of the National Academy of Sciences (PNAS), and point to additional risks of plastic pollution, especially Regarding nanoplastics which can be thousands of times smaller than microplastics.
Research indicates that nanoparticles may be more dangerous due to their small size, which makes it easier for them to penetrate human bodies and cross various barriers. Researchers say that these small particles can enter the blood and interact with cells, leading to disruption of cellular functions and negative effects on health.
Previous studies have indicated that micro- and nano-plastic particles can lead to serious effects on several systems in the human body, including oxidative stress, inflammation, impaired immune function, changes in metabolism and energy metabolism, and many other harmful effects.
This study highlights the importance of thinking about the effects of plastic pollution on human health and encourages taking measures to reduce plastic consumption and improve waste management to reduce this environmental and health impact.
If dangerous nanoplastics are found in bottled water, it raises concerns about the safety of drinking this water as small nanoparticles may be able to interact with human cells, and cause adverse health effects . However, assessing the safety of drinking this water requires additional studies. To determine exposure levels and their actual effects on health.
The study cited in PNAS provides a closer look at the components of bottled water, revealing the presence of nanoplastics in up to 10% of the nanoparticles examined.
It is important to differentiate between types of plastic materials, as the study indicates that there are five dominant types, and among these types, the structure of plastic bottles is mostly formed from PET. Although PET is generally considered safe, research must be continued to verify the effect of particles. nanoparticles discovered.
The study also indicates the presence of other dangerous nanoplastics in water, which indicates the presence of unknown sources of environmental pollution, and this shows the importance of monitoring sources of pollution and implementing measures to reduce the presence of harmful plastics in drinking water.
In general, one should be cautious, follow developments in scientific research on the health effects of nanoplastics, and, if concerned, switch to safer water sources or use stronger water filtration methods to reduce potential exposure to hazards.
