<strong>More than 90 percent of some of the world’s most popular bottled water brands contain tiny pieces of plastic, according to <a href="http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/14_03_13_finalbottled.pdf">a new study</a>. Scientists from the State University of New York wrote that they “found roughly twice as many plastic particles within bottled water,” compared with their <a href="https://orbmedia.org/stories/Invisibles_plastics">previous study</a> of tap water. </strong> <strong>More than 90 percent of some of the world’s most popular bottled water brands contain tiny pieces of plastic, according to <a href="http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/14_03_13_finalbottled.pdf">a new study</a>.

The National Ocean Service, an office within the U.S. Department,<a href="https://oceanservice.noaa.gov/facts/microplastics.html"> defines microplastics</a> as pieces of plastic less than five millimeters long and the effects of ingesting them are unknown.  The U.S. government National Ocean Service<a href="https://oceanservice.noaa.gov/facts/microplastics.html"> defines microplastics</a> as pieces of plastic less than five millimeters long and the effects of ingesting them are unknown.
"When we think about the composition of the plastic ... what actually the particles might do in the body – there's just not the research there to tell us," <a href="http://www.bbc.co.uk/news/science-environment-43389031">said</a> Bruce Gordon, coordinator of the World Health Organization’s (WHO) global work on water and sanitation. "When we think about the composition of the plastic ... what actually the particles might do in the body – there's just not the research there to tell us," <a href="http://www.bbc.co.uk/news/science-environment-43389031">said</a> Bruce Gordon, coordinator of the World Health Organization’s (WHO) global work on water and sanitation.
Gordon also stressed that in countries where tap water is contaminated with sewage this is a far greater known risk than microplastics. <a href="http://www.bbc.co.uk/news/science-environment-43389031">The WHO announced</a> it is launching a review into the potential risks of plastic in drinking water.

The new study, commissioned by not-for-profit journalism organization <a href="https://orbmedia.org/stories/plus-plastic/text">Orb Media</a>, used a dye called Nile Red which binds to pieces of plastic, and can be seen under particular light wavelengths. After screening 259 bottles of water from 11 brands, Professor Sherri Mason, who supervised the study, <a href="http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/14_03_13_finalbottled.pdf">found</a> an average of 10 plastic particles per liter of water, each larger than a human hair, and 93 percent showed some sign of microplastic contamination. Only 17 of the bottles had no plastic particles at all, while one bottle contained more than 10,000 particles per liter. The new study, commissioned by not-for-profit journalism organization <a href="https://orbmedia.org/stories/plus-plastic/text">Orb Media</a>, used a dye called Nile Red which binds to pieces of plastic, and can be seen under particular light wavelengths.

Nestlé, which produces several bottled water brands, responded by saying that the Nile Red dye method could “generate false positives,” because it did include a step in which biological substances are removed from the sample, in a statement to <a class="u-underline" href="http://www.cbc.ca/news/technology/bottled-water-microplastics-1.4575045" data-link-name="in body link"><em>CBC News</em>.</a> "The research results do not correspond to the internal analyses that we conduct on a regular basis." However, <a href="https://orbmedia.org/stories/plus-plastic/text">the study's</a> counter argument to this is Mason noting that the 'digestion step', used on debris-filled samples from the ocean or beaches, wasn't needed for bottled water. She said: "Certainly they are not suggesting that pure, filtered, pristine water is likely to have wood, algae, or chitin [prawn shells] in it?"  Nestlé, which produces several bottled water brands, responded by saying that the Nile Red dye method could “generate false positives,” because it did include a step in which biological substances are removed from the sample, in a statement to <a class="u-underline" href="http://www.cbc.ca/news/technology/bottled-water-microplastics-1.4575045" data-link-name="in body link"><em>CBC News</em>.</a> "The research results do not correspond to the internal analyses that we conduct on a regular basis," it continued.
  However, Mason <a href="https://orbmedia.org/stories/plus-plastic/text">told</a> Orb Media that a so-called "digestion step," applied to debris-filled samples from the ocean or beaches, wasn't needed for bottled water. "Certainly they are not suggesting that pure, filtered, pristine water is likely to have wood, algae, or chitin [from crustacean shells] in it?" she said.
Orb media's<a href="https://orbmedia.org/stories/plus-plastic/text"> study</a> says that polypropylene, which is used in bottle caps, made up 54 percent of the larger particles found in the bottled water. However, it is not clear whether 54 percent of the larger particles found were coming from the plastic in those bottle caps.  The<a href="https://orbmedia.org/stories/plus-plastic/text"> study</a> says that polypropylene plastic, which is used in bottle caps, made up 54 percent of the larger particles found in the bottled water. It is not clear, however, whether these particles actually came from the caps.
