The bottled water of many major brands around the world is contaminated by tiny plastic particles whose health hazards are unknown, says a study published Wednesday.
Researchers have tested the water of more than 250 bottles in nine countries including Lebanon, India and the United States, led by Sherri Mason, a professor at the State University of New York at Fredonia, according to a summary of the published study on the media platform Orb Media
Plastic was found in 93% of these bottled water samples from several brands such as Aqua, Aquafina, Dasani, Evian, Nestle Pure Life or San Pellegrino.
These included polypropylene, nylon and polyethylene terephthalate (PET). On average, the researchers found, in each liter of water, 10.4 particles with a surrounding size of 0.10 millimeters
"I think this comes from the bottling process." I think most of plastic comes from the bottle itself, from its cork, from the industrial bottling process, "Sherri Mason told AFP
" Water in glass bottles also contained microplastics ", reports
A previous study published by Orb Media had shown that plastic particles were also present in smaller quantities in tap water.
The extent of the risks posed by these particles on human health is unknown.
Jacqueline Savitz, North America leader for Oceana, an NGO that fights against pollution of the oceans, said the study provided one more reason to limit the production of water bottles plastic.
"It is more urgent than ever to make plastic water bottles a thing of the past, "said the NGO representative who did not participate in the study.
