A recent study pointed out that a sampling 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, Nestle Pure Life and San Pellegrino.
Beijing March 21 news, according to foreign media reports, a recent survey conducted in nine countries said that many of the world famous brand of bottled water has been contaminated by micro-plastic particles. These plastic particles may be infiltrated into the water during bottling.
The study was chaired by Sherri Mason, a researcher at the State University of New York at Fredonia. The American nonprofit media agency Orb Media released a press release. The researchers tested a total of 250 bottles of water in Brazil, India, Indonesia, Kenya, Lebanon, Mexico, Thailand, and the United States. Plastic particles were detected in 93% of water samples. Brands involved include Aqua and Aquafina. ), Dasani, Evian, Nestle Pure Life and San Pellegrino.
The plastic materials detected include nylon, polyethylene terephthalate (PET), and polypropylene (mainly used for bottle caps). "In this study, we found that 65% of the plastic pellets were actually pieces, not fibers," Mason said in an interview. "I think most of the plastic we see comes from the bottle itself, including caps. It is infiltrated during the industrial bottling process."
The report pointed out that in a bottle of drinking water, the number of plastic particulate contaminants can range from "0 to 10,000." In this study, plastic particles with an average size of 100 μm are considered to be “microplastics”—about 10.4 per litre of water. Smaller plastic particles are higher in content, averaging about 325 per liter of water.
Other brands that have detected plastic contamination include Bisleri, Epura, Gerolsteiner, and Minalba. Researchers said that at present it is impossible to determine the risk of these pollutants to human health.
"These (plastic contaminants) have been 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 compounds in the environment. And plastic contamination is just some way to bring these compounds into our bodies.”
Is it time to abandon plastic bottles?
Orb Media also found plastic particles in tap water in previous studies, but on a smaller scale. "Tap water is generally safer than bottled water," said Mason. In this three-month study, researchers at the School of Chemistry at the University of East Anglia in the United Kingdom used fluorescent Nile dyes (which fluoresce under blue light) to dye, so that they could "see" micro plastic particles in water. . "We conducted an independent review of test results and methodologies to ensure that they were reliable," said 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 "not based on sound scientific methods."
“A scientific study published in the peer review journal Water Research (Water Research) in February 2018 concluded that no statistically significant number of microplastics was found in disposable plastic bottled water,” the statement added. "There is no scientific consensus on the potential health risks of microplastics. There are limitations in the data of this topic, and the conclusions of different studies are quite different."
Jacqueline Savitz, the 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 universal use of plastic water bottles. . “We know that plastic granules are accumulating in marine animals, and that means we are also exposed to plastic pollution, and some people even do it every day,” she said. “The situation is more urgent than ever and it is time for plastic. The bottle has become history."
