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, Nestle Pure Life and San Pellegrino.
Beijing time on March 21, according to foreign media reports, a recent survey conducted in nine countries said that many world-renowned brands of bottled water were contaminated by micro-plastic particles. These plastic granules may penetrate into the water during the bottling process.
The study was moderated by Sherri Mason, a researcher at the State University of New York at Fredonia, and the US non-profit media Orb Media released a research press release. The researchers tested a total of 250 bottles of water in Brazil, India, Indonesia, Kenya, Lebanon, Mexico, Thailand, and the United States, and plastic particles were detected in 93% of the water samples, including Aqua, Aquafina. ), Dasani, Evian, Nestle Pure Life, and San Pellegrino.
The detected plastic materials include nylon, polyethylene terephthalate (PET) and polypropylene (mainly used for making caps). “In this study, 65% of the plastic particles we found were actually fragments, not fibers,†Mason said in an interview. “I think most of the plastic we see comes from the bottles themselves, including the caps. They It is infiltrated during the industrial bottling process."
According to the report, the amount of plastic particulate contaminants can range from “0 to over 10,000†in a bottle of drinking water. In this study, plastic pellets with an average size of 100 microns - considered "microplastic" - were approximately 10.4 per liter of water. Smaller plastic pellets are higher, with an average of 325 per liter of water.
Other brands that have been found to contain plastic contaminants include Bisleri, Epura, Gerolsteiner, and Minalba. Researchers say it is not yet possible to determine the health risks of these pollutants.
"These (plastic contaminants) are linked to an increase in certain cancers, as well as a decline in the number of sperm and an increase in problems such as ADHD and ADHD," Mason said. "These problems are all related to chemically synthesized substances in the environment. And plastic pollution is just some way to bring these compounds into our bodies."
Is it time to abandon the plastic bottle?
In previous studies, Orb Media also found plastic particles in tap water, but on a smaller scale. “The tap water is generally safer than bottled water,†Mason said. In this three-month study, researchers at the School of Chemistry at the University of East Anglia in the United Kingdom used fluorescent Nile red dyes (which fluoresce under blue light) to "see" microplastic particles in water. . “We conducted an independent review of test results and methodologies to ensure their authenticity,†said Andrew Mayes, head of research at the University of East Anglia.
However, in the International Bottled Water Association's statement, representatives from bottled water producers questioned the results, claiming that the results were not peer-reviewed and “not based on sound scientific methodsâ€.
“A scientific study published in the peer-reviewed journal Water Research in February 2018 concluded that no statistically significant amount of microplastics was found in disposable plastic bottled water,†the statement added. “There is no scientific consensus on the potential health risks of microplastics. The data on this topic has limitations, and the conclusions of different studies are very different.â€
Jacqueline Savitz, chief policy officer for ocean protection organization Oceana North America, did not participate in the study, but she said the study provided 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 it every day,†she said. “The situation is now more urgent than ever, it’s time to get plastic The bottle has become history."
