[China Packaging News] a recent study pointed out that a sampling survey of many important bottled drinking water brands found that 93% of water samples detected plastic particles. These brands include aqua, Aquafina, Dasani, Evian, Nestle pure life and San Pellegrino

on March 21, Beijing time, 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 particles may have seeped into the water during bottling

the study was hosted by Sherri Mason, a researcher at the State University of New York at Fredonia, and orb media, a non-profit aggregation media in the United States, released the draft of the research report. 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 the water samples, involving brands such as aqua, Aquafina, Dasani, Evian, Nestle pure life and San Pellegrino

the detected plastic substances include nylon and polyethylene terephthalate. Manufacturers should also consider the dynamic performance and synchronization of machine movement. Polyethylene (PET) and polypropylene (polypropylene also supplies cantilever impact testing machine, impact testing machine and other products ne, which are mainly used to make bottle caps). "In this study, 65% of the plastic particles we found are actually fragments, not fibers," Mason said in an interview. "I think most of the plastic we see comes from the bottle itself, including the bottle cap. They infiltrate in the process of industrial bottling."

the report points out that the amount of plastic particulate pollutants in a bottle of drinking water can range from "0 to more than 10000". In this study, plastic particles with an average size of 100 microns - known as "microplastics" - are about 10.4 per liter of water. The content of smaller plastic particles is higher, with an average of about 325 per liter of water

other brands detected to contain plastic pollutants include bisleri, epura, gerolsteiner, minalba, etc. Researchers said that at present, the risks of these pollutants to human health cannot be determined

"these (plastic pollutants) are related to the increase of some cancers, the decline of sperm count and the increase of problems such as ADHD and ADHD," Mason said. "These problems are related to chemical synthetic substances in the environment, and plastic pollution is a way to bring these compounds into our body."

is it time to abandon plastic bottles

orb media also found plastic particles in tap water in previous studies, but the scale is small. "Tap water is generally much safer than bottled water," Mason said. In this three-month study, researchers from the school of chemistry at the University of East Anglia in the UK used fluorescent Nile red dye (which fluoresces under blue light) to dye, so that they can "see" micro plastic particles in water. "We independently reviewed the test results and methodology to ensure their authenticity and reliability," said Andrew Mayes, head of research at the University of East Anglia, who is expanding the field of plastic utilization

however, in the statement of the international bottled water association, representatives from bottled water producers questioned the research results for too many times, claiming that these results had not been peer-reviewed and "were not based on reasonable scientific methods"

"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 of this subject have limitations, and the conclusions of different studies are very different."

Jacqueline Savitz, chief policy officer of Oceana North America, a marine conservation organization, was not involved in the study, but she said that 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, which means that we are also exposed to plastic pollution, and some people even do it every day," she said. "The situation is more urgent than ever before, and it is time to make plastic bottles history."
