A recently released study tested 259 water bottles from 11 brands sold across nine countries, including the United States, and found that 93% of those tested contained microplastic contamination. The research, which was conducted by researchers at the State University of New York at Fredonia and non-profit journalism organization Orb Media, found an average of 10.4 plastic particles per liter of water, which is twice the amount of contamination found in tap water, according to another Orb Media investigation.
Researcher Sherri Mason of the State University of New York at Fredonia told AFP that 65% of the plastic particles found were "fragments" of plastic, and included the plastic used to make some bottle caps.
The International Bottled Water Association President and CEO Joe Doss said in a statement that the "non-peer reviewed study" isn't based on sound science, and the "study's findings do nothing more than unnecessarily scare consumers."
"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."
