Many leading brands of water supplied in plastic bottles are contaminated with tiny particles that are seeping in during bottling, according to a major study involving samples from nine countries.
Researchers tested 250 bottles of water in Brazil, China, India, Indonesia, Kenya, Lebanon, Mexico, Thailand, and the United States.
Plastic was identified in 93% of the samples of water from Aqua, Aquafina, Dasani, Evian, Nestle Pure Life, and major brands available in Portugal, Evian and San Pellegrino.
“Widespread contamination” with plastic was found in the study, led by microplastic 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.
The plastic debris included polypropylene, nylon, and polyethylene terephthalate (PET), which is used to make bottle caps.
“In this study, 65% of the particles we found were actually fragments and not fibers,” Mason said.
“I think it is coming through the process of bottling the water. I think that most of the plastic that we are seeing is coming from the bottle itself, it is coming from the cap, it is coming from the industrial process of bottling the water.”
Particle concentration ranged from “zero to more than 10,000 likely plastic particles in a single bottle,” reads the report.
On average, plastic particles in the 100 micron (0.10 millimeter) size range - considered “microplastics,” - were found at an average rate of 10.4 plastic particles per litre.
Even smaller particles were more common — averaging about 325 per litre.
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.”
“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” microplastic particles by staining them using fluorescent Nile Red dye, which makes plastic 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 plastic 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 plastic water bottles a thing of the past.”

WAS in GLASS. Whatever happen to change that?
Water filters are a possibility.
A good particle filter would remove offending plastics from bottles water and RO filters apparently render tap water safe.
aren't we lucky little beggars to live in a modern European state in 2018
What is the alternative to plastic bottles with plastic bottle caps?
