The study was the largest one of its kind with over 250 bottles from 11 brands being tested, the bottles came from 19 locations across nine countries. More than 90% contained plastic with levels twice as high as those in tap water.
What this study has really highlighted though, is the amount of uncertainty when it comes to the safety of bottled water. The implications that these particles may pose is unknown and as a result the World Health Organization (WHO) has announced a review of the risk of plastic in drinking water. There are also no regulations or standardised testing concerning microplastics.
As water scarcity is becoming a more prominent issue around the globe, especially in places like Cape Town, not only is the future availability of water a concern but also the quality and subsequent implications to people and the environment alike.
