A new study by scientists from the State University of New York has found that more than 90 percent of bottled water worldwide is contaminated with tiny pieces of plastic.
The researchers tested 259 individuals bottles across 11 brands from 9 countries including Brazil, China, India, Indonesia and the United States. Top global brands including Aquafina and Evian were tested.
Although bottling companies are insisting that they enforce strict quality control, finding indicating presence of carcinogenic substance in the water raise concerns about the long-term implications for public health. Polypropylene, used to make plastic bottle caps, was the most common polymeric material found in the samples while nylon was the second most abundant.
After accounting for possible laboratory contamination, 93 percent of bottled water showed some presence of micro plastics. Researchers found an average of 10.4 micro plastic particles per liter of bottled water using spectroscopic analysis. The data indicated the contamination is at least partially coming from the packaging or bottling process itself.
