The world’s leading brands of bottled water are contaminated wit
h tiny pl
astic particles that are likely seeping in during the packaging process, according to a major
study across nine countries published Wednesday.
‘Widespread contamination’ with pl
astic was found in the study, led by micropl
astic researcher Sherri Mason of the State University of New York at Fredonia, according to a summary released by Orb Media, a US-based non-profit media collective.
Researchers tested 250 bottles of water in Brazil, China, India, Indonesia, Kenya, Lebanon, Mexico, Thailand, and the United States.
Pl
astic was identified in 93 percent of the samples, which included major name brands such as Aqua, Aquafina, Dasani, Evian, Nestle Pure Life and San Pellegrino.
The pl
astic debris included polypropylene, nylon, and polyethylene terephthalate (PET), which is used to make bottle caps. “In this study, 65 percent of the particles we found were actually fragments and not fibres,” Mason said.
“I think it is coming through the process of bottling the water. I think that most of the pl
astic that we are seeing is coming fr
om the bottle itself, it is coming fr
om the cap, it is coming fr
om the industrial process of bottling the water.”
Particle concentration ranged from zero to more than 10,000 likely pl
astic particles in a single bottle, said the report.
On average, pl
astic particles in the 100 micron (0.10 millimeter) size range – considered microplastics – were found at an average rate of 10.4 pl
astic particles per litre.
Even smaller particles were more common – averaging about 325 per litre.
Oth
er brands that were found to contain pl
astic contaminated included Bisleri, Epura, Gerolsteiner, Minalba and Wahaha.
Experts cautioned that the extent of the risk to human health posed by such contamination remains unclear. “There are connections to increases in certain kinds of cancer to lower sperm count to increases in conditions like ADHD and autism,” said Mason. “We know that they are connected to these synthetic chemicals in the environment and we know that plastics are providing kind of a means to get those chemicals into our bodies.”
Previous research by Orb Media has found pl
astic particles in tap water, too, but on a smaller scale. “Tap water, by and large, is much safer than bottled water,” said Mason.
The three-month
study used a technique developed by the University of East Anglia’s School of Chemistry to see micropl
astic particles by staining them using fluorescent Nile Red dye, which makes pl
astic fluorescent when irradiated with blue light. “We have been involved with independently reviewing the findings and methodology to ensure the
study is robust and credible,” said lead researcher Andrew Mayes, from UEA’s School of Chemistry. “The results stack up.”
Jacqueline Savitz, chief policy officer for North America at Oceana, a marine advocacy group that was not involved in the research, said the
study provides more evidence that society must abandon the ubiquitous use of pl
astic water bottles.
“We know plastics are building-up in marine animals, and this means we too are being exposed, some of us, every day,” she said. “It’s more urgent now than ever before to make pl
astic water bottles a thing of the past.”
