Recent research has raised the alarm over the potential health impacts of consuming water from plastic bottles, with scientists concerned over the chemicals that can leach into the liquid with unknown impacts on human health. A new study has investigated this phenomenon with regard to bottles of the reusable variety, revealing that they release hundreds of chemicals into the water and why putting them through the dishwasher may be a bad idea.

The study was carried out by researchers at the University of Copenhagen and focused on the type of soft and squeezy bottles used in sports. While these are incredibly commonplace around the world, the authors say there is a big gap in our knowledge around how chemicals from these plastics can migrate into the drinking water they hold, so they conducted experiments to fill in some of the blanks.
