A recent study pointed out that a sample survey of many important bottled drinking water brands found that plastic particles were detected in 93% of water samples. These brands include Aqua, Aquafina, Dasani, Evian, and Nestlé. (Nestle Pure Life) and San Pellegrino et al.
According to foreign media reports, a recent survey conducted in nine countries stated that bottled water from many world-famous brands was contaminated by microplastic particles. These plastic particles may be in the bottling process. Penetrate into the water.
The study was chaired by Sherri Mason, a researcher at the State University of New York at Fredonia, USA. Orb Media, a nonprofit media agency in the United States, issued a research report. The researchers are based in Brazil, India, and Indonesia. , Kenya, Lebanon, Mexico, Thailand, and the United States detected a total of 250 bottles of water, 93% of which detected plastic pellets. Brands involved included Aqua, Aquafina, Dasani , Evian, Nestle Pure Life and San Pellegrino.
The plastic materials detected included nylon, polyethylene terephthalate (PET) and polypropylene (mainly used for bottle caps). 'In this study, we found that the plastic particles 65% is actually debris, not fiber,' Mason said in an interview. 'I think most of the plastic we see comes from the bottle itself, including the caps. They are infiltrated during the industrial bottling process.'
The report points out that in a bottle of drinking water, the number of plastic particulate contaminants can range from '0 to more than 10,000'. In this study, plastic particles with an average size of 100 microns are considered to be 'microplastics' - About 10.4 per liter of water. Smaller plastic particles are higher, with an average of about 325 per liter of water.
Other brands that have detected plastic contaminants include Bisleri, Epura, Gerolsteiner, and Minalba. Researchers say that the risks of these pollutants to human health cannot be determined.
'These (plastic contaminants) are linked to the increase in certain cancers and the decline in sperm counts and the increase in problems such as ADHD and ADHD,' Mason said. 'These problems are related to chemical synthetic substances in the environment. Plastic contamination is just some way to bring these compounds into our bodies.
Is it time to abandon plastic bottles?
Orb Media's previous research also found plastic particles in tap water, but on a smaller scale. 'Tap water is generally safer than bottled water,' Mason said. In this three-month study, East Anglia, UK Researchers at the Faculty of Chemistry at Leah University use fluorescent Nile dye (which emits fluorescence under blue light) to dye, so that it can 'see' micro-plastic particles in the water. 'We conducted an independent review of test results and methodologies. Make sure it's true and reliable,' said the research director, Andrew Mayes of the University of East Anglia.
However, in the statement of the International Bottled Water Association, representatives from bottled water producers questioned the results of the study, claiming that these results have not been peer-reviewed, and that 'not based on sound scientific methods'.
A scientific study published in the peer-reviewed journal Water Research in February 2018 concluded that no statistically significant number of microplastics was found in disposable plastic bottled water,' added the statement. Road, 'There is no scientific consensus on the potential health risks of microplastics. The data of this topic has limitations, and the conclusions of different studies are very different.'
Jacqueline Savitz, chief policy officer of the marine conservation organization Oceana North America, did not participate in the study, but she said that the study provides more evidence that we must stop the widespread use of plastic water bottles. "We know that plastic particles are accumulating in marine animals, and that means we are also exposed to plastic pollution. Some people even do this every day, ' she said. 'The situation is more pressing now than ever before. Plastic bottles have become history.
